Building foundations are usually too frail to carry the weight of a superstructure on their own. There are various methods to lower the intensity of loads and fortify the soil. One of the most widely used deep foundation techniques worldwide is piling. Modern piling solutions are very advantageous to the construction project because they are the most efficient method for deep foundation. How Are Piles Utilised in Construction Techniques? In order to convey and transfer loads to the soil, piles are driven or drilled through the ground along a specific length of the land. In general, piles are typically used when the soil’s load capacity is insufficient to support the structural weight of the building. Through piling, the loads are transferred by the piles to a depth of solid earth. For deep foundation projects, piling is utilised to ensure that the building structure is supported both above and below ground. Piling rigs are simply inserted into the earth up to bedrock. The weight of what is above ground can then be safely and firmly supported by the pile. In general, additional attachments like conical tips are frequently added to the pile in order to drive it more effectively. According to the design requirements of the contractor in charge of the project, these attachments are welded to the end of the pile. The Birth of Piling Pile construction has a long history. It started with the construction of foundations on flimsy peat soils next to rivers in prehistoric times. In order to ensure adequate protection of the land as well as the supply of water, many villages and cities were situated close to lakes and rivers. As a result, timber piles that were either driven into the ground manually or fastened into holes that were filled with stones and sand were used to strengthen the poor bearing ground. There were numerous instances in Britain where timber piles were used. Throughout history, piling has been mentioned in numerous books of various genres. Swiss settlers and lake dwellers used piling years ago and built structures on piled foundations to elevate their homes. The constant demand for buying land has compelled governments and development organisations to use property with poor soil qualities. Piling is essential to the modern construction sectors. What Kinds of Pilings Are There? Building engineers must evaluate the parameters of their construction site, including the soil, climate, and other elements, before deciding between piling types. In order to comprehend the scope of their infrastructure project, they will also need to engage with architects. With the use of this knowledge, they can plan for building solutions and select the ideal piling type. Friction piles and end-bearing piles are the two primary forms of piling that are used in construction. Friction Piles The way friction piles withstand the loads placed on buildings is by growing their capacity to support loads through skin shear stresses. Skin friction develops when the pile surface and the surrounding dirt adhere to one another or rub against one another. All of the pile surfaces efficiently resist the load due to friction or adhesion, which also lowers the bulb pressure on the pile surface. When using friction piles, a pressure zone of cylindrical shape forms around the pile surface. End Bearing Piles End bearing piles are used to transmit superstructure load from a weak stratum, (such as rock or extremely dense sand and gravel) to a strong stratum with a higher bearing capacity. The resistance of the dense soil layer at the pile’s end serves as the primary indicator of their load-bearing capabilities. At least three times the pile’s diameter must be inserted from the pile’s end into the hard strata. This action is thought to fully exploit the layer’s ultimate strength beneath the pile tip. End-bearing piles can be constructed using prefabricated piles. Pile Construction Techniques A broad variety of pile types are available for applications with diverse soil types and structural requirements. Pile techniques can be determined by their fundamental design purpose. Driven Piles Aggregate Piles Bore Piles Screw Piles Driven Piles Displacement piles, often referred to as driven piles, are a popular kind of deep foundation that supports structures by transferring their weight to strata of rock or soil that are strong enough to hold the weight and have the suitable settlement properties. Driven piles are frequently employed as the most economical deep foundation method in order to support buildings, walls, towers, and bridges. They can also be used for projects like cofferdams and anchorage structures. Driven piles are used for retaining walls, bulkheads, and embankments. Bore Piles Replacement piles, also known as bore piles, are widely used for building foundations. They can support structures by shifting their weight to the soil that is suited for settling and have a sufficient bearing capacity. Bore heaps are piles where the removal of debris creates a hole. Then reinforced concrete is poured into that hole. In contrast to displacement piles, which are driven or screwed into the ground to push the soil away, replacement piles are used to replenish spoil. Bore piles are typically used in cohesive subsoils in order to create friction piles and build pile foundations adjacent to existing structures. There are two frequently utilised kinds of bored pile foundations known as rotary bore and CFA piling. Piling Fitted with a Rotary Bore Rotary bore piling is utilised by construction companies when there are severe impediments on the earth. This piling rig installs a temporary shell to act as support for the structure. A revolving cage is inserted into the ground to reinforce unstable soil, and the pile is then extracted using an auger unit. After the bore has been carefully cleaned to the proper depth and the pile has been inserted, the casing is removed, leaving the finished pile behind. Rotary Bore Piles are used to fortify the ground. That way, the ground can hold the load of the structure that will be erected on top of it. In this method, drilling is done

Piling is a broad term and refers to numerous foundation-building & reinforcing techniques. Foundations of any construction project must be flawless to ensure that the superstructure and all that traverse it are safe. The type and measurements of foundations are decided by engineers who perform a series of calculations and carry out a detailed study of the site soil. Depending on these factors, it is determined whether a project should have a shallow or a deep foundation. Engineers usually go for shallow foundations if the site soil is suitable and has adequate load-bearing capacity. However, engineers will go for deep foundations if the LBV (load-bearing value) of the surface layers and the soil characteristics are not ideal. There are numerous methods of building deep foundations, and piling is one of them. Once it is understood that piling is the preferable method, engineers must sit together to identify the type of piling required. Several factors must be considered, including cost, time, regulations, and site conditions, before they agree on the method. Let us read about five of the most common piling techniques used by construction companies for residential, commercial, industrial, and public projects. Bored Piling Replacement piles/ Bored pile foundations are usually poured in place for supporting infrastructure by transferring their weight/load to rock or soil layers with good settlement characteristics and high load-bearing capacity. The process involves drilling vertical holes into the ground with the help of a piling machine. Steel cylinders or sleeves are drilled into the ground, followed by concrete pouring. SFA (Sectional flight auger) and CFA (Continuous Flight Auger) are the two most common methods for preparing bored foundations. Applications of Bored Piles Bored pile foundations are ideal for challenging soil conditions and well suited to tolerating considerably heavy loads. Apart from being used for building foundations, they are often used for building structural underground walls for earth retention. Secant pile walls (overlapping piles) are often used for controlling groundwater migration. Bored Pile Advantages Different lengths of piles can be created for passing through compressible, soft, and unsuitable soil to stronger bearing strata. They can be extended much deeper to protect from moisture variation and frost penetration. Less disruptive to nearby soil. Minimal disturbance to nearby structures because of low vibration. High capacity and economics. Driven Piling Driven piles are built using vibration by driving or hammering steel casings (permanent or temporary) into the ground. They are ideal for building foundations at construction sites with highly cohesive or contaminated soil and for areas with high water tables. They can be prepared both on-site and off-site. The former uses pre-cast piles and can be fabricated from concrete, wood, composite, or steel. Steel-driven piles are of several types, including H-section (used for marine structures), screw piles (sand and soft silt), and tube piles (soft subsoils, marine structures). Concrete-driven piles can have several shapes, including sheets, cylindrical, octagonal, or square. They are driven into the ground using percussion. They are highly suitable for extremely loose soils and soils with running water. Timber piles are also percussion driven and available in various shapes. They are used for construction near estuaries and river banks.   Advantages of Driven Piles Driven Piles can be prepared off-site, reducing chances of errors and installation time. Driven piles do not require soil extraction and do not lead to structural problems or subsidence. Their installation displaces and compacts the soil, which enhances the pile’s bearing capacity. They are highly cost-effective as they can be constructed in different shapes from different materials. They have high structural strength. They have high bending and lateral resistance, which makes them suitable for complex conditions such as seismic loading, water, wind, etc. Screw Piling Screw piles look like huge screws with helices attached to them. The pile shafts are usually circular and hollow and are mainly constructed from galvanised steel. Just like the screws you use, screw piles are fastened into the soil with the help of rotary hydraulic tools fitted on earthmoving machines. Screw piles are ground anchoring systems highly suitable for deep foundations, and they transfer the infrastructure’s load onto the pile. Screw piles minimise the spoil (excavated soil), usually created using other methods. This makes it more cost-effective in several situations. Screw pile foundations for various projects, including roads, telecommunications, rail, retaining structures, masts, and several others. Advantages of Screw Piles The installation time of screw piles is much lower than many other piling methods. The installation cost is much lower than other piling methods A range of screw sizes can be used. Screw piles leave a much lower carbon footprint. Their usage eliminates the need for excavation and therefore backfilling. They can be installed close to other structures without causing any damage. They can be easily removed if they are not required. Sheet Piling Sheet piling is a type of drive piling. The sheets are usually constructed from steel and have interlocking edges. Sheets can also be built from concrete or timber. The sheets are driven into the earth to provide excavation support. They are also often used for creating temporary or permanent retaining walls at construction sites where extensive excavations must be carried out. Other applications include building underground structures such as car parking, basements, and tunnels., They are also used for land reclamation, cofferdams, seawalls, and many more. Timber sheets are mainly used temporarily or for resisting mild lateral loads. Reinforced concrete sheets are manufactured by linking together pre-cast concrete. Steel sheets are preferred when a higher resistance is required. They are available in several forms, including straight web sections, box sections, composite and normal sections. Advantages of Sheet Piling Sheet piles are reusable and recyclable. They come in a wide variety of lengths and sizes. Both permanent and temporary structures can be built. Low-vibration methods can be used to install them in highly populated areas. The construction site remains clean, as there is no spoilage. Sheet piling installation time and cost are considerably low. They are highly suitable for both below and above-water usage.

Piles are structural elements that transfer loads of a building or structure to deeper, more stable layers of soil or rock. These are typically long, slender columns made of different materials such as steel, concrete, or timber. They are bored or driven into the ground to support the structure’s weight. Pile foundations are commonly used in situations where the soil near the surface is not strong enough to support the structure’s weight or where the structure must be supported on soft, compressible soils or slopes. This blog will discuss the brief history of piling along with its types and materials. Evolution History of Piling The use of pile foundations can be traced back to ancient times when wooden piles were used to support structures built on soft soil or marshy ground. In fact, the oldest known pile-supported structure is 6000 years old in Switzerland, where wooden piles were used to support buildings made of brick and stone. In the Roman era, piles made of stone or timber were used to support bridges, aqueducts, and other structures. The Romans also used piles to support their famous Colosseum, which was built in the first century AD. During the Middle Ages, pile foundations were commonly used in Europe to support structures such as cathedrals and castles. Wooden piles were used extensively and were often driven into the ground using a heavy hammer or a pile driver. In the 19th Century, pile foundations became more common and sophisticated with the advent of new materials such as concrete and steel. The introduction of steam-powered pile drivers made it possible to drive piles deeper into the ground and to support much heavier loads. In the 20th Century, the development of hydraulic pile drivers and other specialised equipment further improved the efficiency and effectiveness of pile foundations. Today, pile foundations are widely used in the construction of buildings, bridges, highways, and other structures that require a solid foundation on soft or unstable soil. Types of Pile Foundations End-Bearing Piles: These piles are designed to transfer the load of the structure to a hard layer of rock or very dense soil at the bottom of the pile. End-bearing piles are usually made of concrete or steel and are often used for structures with heavy loads, such as high-rise buildings, bridges, and transmission towers. The piles are usually driven into the ground by hammering them with a pile driver until they reach the hard layer. Friction Piles: These piles are designed to transfer the load of the structure to the surrounding soil by frictional forces between the soil and the surface of the pile. Friction piles are typically used in soft soils or where the soil layer is not thick enough to support the structure. They can be made of concrete or steel and are usually driven into the ground by a pile driver until the desired depth is reached. Compaction Piles: These piles are designed to improve the load-bearing capacity of loose or weak soils by compacting the soil around the pile. Compaction piles are usually made of pre-cast concrete or steel and are driven into the ground by a pile driver until they reach the desired depth. After driving the pile, the soil around it is compacted using a vibrating hammer to increase its density. Anchor Piles: These piles are designed to support structures subject to uplift forces, such as tall buildings or bridges. Anchor piles are typically made of steel and anchored to a solid rock or dense soil layer using a steel cable or rod. A pile driver drives the anchor pile into the ground, and the cable or rod is attached to the structure to provide additional support. Sheet Piles: These piles are designed to provide lateral support to excavations, retaining walls, and cofferdams. Sheet piles are usually made of steel or concrete and are driven into the ground to form a continuous wall. They are often used in areas with limited space for excavation, and they can be installed quickly and efficiently. Bored Piles: These piles are created by drilling a hole in the soil and pouring concrete into it. Bored piles are often used in soils that are difficult to drive piles into or in areas with restricted headroom. They are typically made of reinforced concrete and can be used for both end-bearing and friction piles. Different Materials for Piling Some of the materials commonly used for pile foundations include: Concrete Piles: These are made of reinforced concrete and are suitable for heavy structures and difficult soil conditions. They can be pre-cast or cast-in-situ and can be either driven or drilled into the ground. Steel Piles: These are made of steel and are used for both small and large structures. They are suitable for soils that are difficult to penetrate and offer high resistance to corrosion. Timber Piles: These are made of wood and are suitable for light structures and soft soil conditions. They are easy to handle and can be easily cut to any length. Composite Piles: These are made of a combination of materials, such as concrete and steel or steel and fibreglass. They offer the advantages of both materials, such as high strength and resistance to corrosion. Screw Piles: These are made of steel and screwed into the ground using a piling rig or other equipment. They are suitable for light structures and soils that are easy to penetrate.   Classification of Piles According to the British Standard Code of Practice for Foundations Large Displacement Piles (Driven Types) Round or square timber Piles Pre-cast concrete piles with solid or tubular sections Prestressed concrete piles Steel tube Piles driven with closed end Fluted and tapered steel tube Steel box piles driven with closed end Jacked-down solid concrete cylinder Jacked-down steel tube with closed end Large Displacement Piles (Driven and Cast-in-situ types) Pre-cast concrete shell filled with concrete Steel tube driven and withdrawn after placing concrete Thin-walled steel shell driven by the withdrawable mandrel and filled with concrete Small Displacement Piles Prestressed concrete piles

What are Grundomat Piles? First, Grundomat is a word that refers to a tool to drive the piles. Grundomat pile is a method of driving piles using condensed and compressed air. This compressed air is generated through a small machine outside where the piles are being driven. This makes it an appropriate solution and technique for confined, restricted areas and underground environments. To drive Grundomat piles, steel tubes ranging from 100 mm to 150 mm are driven deep into the ground until the required depth is achieved. Additionally, extra tube sections are also added, they are then welded to achieve the right design depth. Technical specifications Standard diameters 100 up to 150 mm Allowable bearing capacity up to 90 kN What are Grundomat Piles Used For? They are suitable for domestic construction projects such as underpinnings or extensions. They are also used in the industrial sectors Grundomat piles are appropriate for lightweight construction projects. Fields of Application and its Environmental Impact The following are the fields where grundomat piles are successfully applied: Grundomat piling is used in areas with narrow, confined and difficult access – such as underground sites and basement Areas where less vibration and noise are required. Small house extensions projects like orangeries, gardening rooms, porches in a residential area and conservatoires. The environmental impact of grundomat piling: There is limited noise pollution No loud vibration is generated while driving piles There is no need to remove soil One does not need a piling rig The compressed air can be provided and generated afar from the construction site. The Construction Process of Grundomat Piling The thin wall tube that emits air is positioned precisely over the required area. This tube is filled with a dry mix or limestone plug. Then, at the base of the tube, a pneumonic mole is used to compact a plug. Grundomat is attached and connected to an air compressor from the other end. Additional tube portions are welded when necessary, and bottom driving is continued while the welding is repeated as driving progresses. When the required design depth is achieved, the pile driving ends. Next, the steel cylinders are lined with reinforcement. In the end, concrete or grout is used to fill the steel tubs. Benefits of Grundomat piling Using lightweight machinery generates minimal vibration, which makes this technique great for an environmentally sensitive area. There is no need for piling rigs or heavy-weight machinery. Grundomat piles are easily driven with restricted access and limited headroom. The installation process is swift yet efficient and accurate. It can be fit through doorways if to be used internally.

Grouting is the process of inserting a fluid material into voids, cracks, or spaces to either fill or seal them. The fluid material, known as grout, can be made from cementitious, chemical, or bentonite materials depending on the application. It is an essential process in construction and maintenance activities, providing structural stability and durability to buildings, bridges, tunnels, and other infrastructure. Grouting also helps prevent water intrusion, soil erosion, and subsidence for a structure, prolonging its service life. Without grouting, many structures would be vulnerable to damage and collapse, making it a critical component in ensuring the safety and integrity of the building during and after construction. Let’s uncover more about grouting to understand it more deeply. History of Grouting According to some sources, grouting has a long history dating back to ancient civilisations, where it was used to fill the gaps between stones in masonry structures. But, the modern era of grouting began in the 19th century with the development of Portland cement, which enabled the production of cementitious grouts. During World War II, grouting was critical in constructing military infrastructure such as airfields, bunkers, and tunnels. The post-war period saw a significant expansion of grouting applications in civil engineering, including the construction of dams, bridges, and high-rise buildings. Grouting has become more advanced in recent years with computer-controlled injection systems, enabling precise injection control and real-time grout distribution monitoring. It is now essential for construction, maintenance, and repair and is a crucial factor in ensuring the safety and durability of the building environment. Types of Grouting Cement Grouting Cement grouting is a process of injecting a mixture of cement, sand, water, or other additives, into voids, cracks, or fractures in various construction materials such as concrete, masonry, or rock. The grout mixture is pumped into the cavities under pressure to fill the space and create a solid, homogeneous mass. This grouting method is commonly used for repairing and strengthening structures such as buildings, bridges, dams, tunnels, and underground pipelines. The grouting material can also be used for soil stabilisation and ground improvement, as it can provide increased bearing capacity and improve the stability of the soil. Chemical Grouting In chemical grouting, a chemical grout material is injected into voids, fractures, or gaps in construction materials to create a solid and stable structure. The grout material is a specialised chemical compound that sets and hardens, creating a strong and durable mass. Two techniques are commonly used for efficient chemical grouting: One-Shot Process: A pre-mixed grout is pumped into the material under pressure, causing it to flow through the pores. This method is used for boreholes. Two-Shot Process: The pipe is inserted first into the ground with the help of a drill, followed by the chemical material pumped via the pipe. Resin Grouting A resin material is injected into voids, fractures, or gaps in construction materials such as concrete, masonry, or rock. It is used in worktops, hospitals, food production facilities, and kitchen counters. The resin material is a two-part mixture that sets and hardens, creating a strong and durable bond between the material and the surrounding structure. Bentonite Grouting A bentonite clay mixture is injected into the ground to seal and stabilise soil and prevent water infiltration. Bentonite is a natural clay that expands when wet and forms a waterproof barrier, making it ideal for grouting applications. Bentonite grouting is commonly used in geotechnical engineering, such as for the construction of dams, tunnels, and underground pipelines, as well as for the stabilisation of soil and excavation sites. Bituminous Grouting A bitumen-based material is inserted into cracks, voids, and gaps in construction materials to seal and waterproof them. Bitumen is a petroleum-based material that is viscous and adhesive, making it ideal for grouting applications. Bituminous grouting is commonly used for sealing and waterproofing concrete and masonry structures and filling gaps and cracks in asphalt pavements. It is an effective and durable solution for preventing water infiltration and protecting structures from water damage. Structural Grouting Structural grouting is commonly used for foundation repair, bridge strengthening, and other applications where the stability and safety of the structure are critical. It is an effective and long-lasting solution for improving the structural integrity of buildings and other infrastructure. A specialised grout material is inserted in the gaps in construction materials to improve their load-bearing capacity and stability. The grout material is a mixture of cement, sand, and water or other additives that sets and hardens, creating a solid mass that strengthens and stabilises the structure. The Process of Grouting The grouting process consists of three main stages: preparation, injection, and post-injection. Preparation Surface Preparation: The surface to be grouted is cleaned and prepared to ensure optimal adhesion and penetration of the grout material. Equipment Preparation: The injection equipment is inspected, calibrated, and set up according to the grouting specifications. Mix Preparation: The grout material is mixed according to the manufacturer’s instructions and checked for consistency and flowability. Note: These are the most commonly used ratios for mixing grouting powder and water. For Pourable Grouting – Powder: Water= 0.12 to 0.14 by weight: 3.6 to 4.2 litres of water/ 30 kg bag. For Flowable Grouting – Powder: Water = 0.14 to 0.16 by weight: 4.2 to 4.8 litres of water/ 30 kg bag. Injection Grouting Techniques: The injection technique depends on the grout type, the application, and the desired results. The common techniques include permeation, pressure, and compaction grouting. Injection Pressure: The injection pressure is set according to the specifications and adjusted during the injection process to ensure optimal grout penetration and distribution. Grout Flow Rate: The grout flow rate is controlled to ensure the desired volume of grout is injected and to prevent excess grout from escaping. Post-Injection Curing: The grout can cure according to the manufacturer’s instructions to achieve the desired strength and stiffness. Cleaning: Excess grout and any debris are removed from the injection area to prevent interference with the grouted structure’s performance. Inspection: The grouted area is inspected for defects or voids and re-grouted if necessary. The performance of the grouted structure
