What is SCD Piling?
SCD (Steel Cased Driven) Piling is a bottom-driven piling using a vibrating mole or a drop hammer piling rig driven into a soft unstable ground until a competent load-bearing level is reached. Once the set target is achieved, the pile is reinforced with steel, ensuring no groundwater enters the pile casing.

Process of SCD Piling
Steel Cased Driven Piling method is as follows:
Drop hammer pilling rig has a cylindrical shape used within the casting.
Once the tube is positioned in the right place, a plug is formed to seal the bottom of the tube.
The ground compacts as the weight goes down the tube and strikes the bottom shoe, driving the case deeper into the ground.
Next, additional tube elements of limited strength are added.
These tubes are driven to the required and appropriate installation depth.
Next, the concrete is cast.
Lastly, the weight is drawn to place a single steel bar within the pile for additional reinforcement.
As the pile is filled with strength, it is left to set.
Steel Case Piles: Fields of Application
SCD piling is used in confined and narrow places, including hard-to-reach areas with restricted headroom.
Ideal for contaminated and aggressive soil conditions.
This type of piling is suitable and appropriate for soils with a strong water flow where the casing protects the newly laid concrete.
Suitable for piling through cavities.
Works great in situations where the cut-off level is higher than the ground level.
Additionally, SCD piling is used in industrial projects, railway works, infrastructures, housing constructions, renovations and hydraulic engineering.

The steel cased piles provide strength, security and high degree of timeliness.
Weather conditions cannot limit the use of steel sheet piles.
FAQ
Frequently Asked Questions
Piling is the process of inserting structural piles into the ground that will become the base of the building. Piles are required where soil and earth are performing poorly and are used to spread the load of a building and firm the ground. They are a cost-effective approach to combating corrosion and are proven to significantly improve the life expectancy of a structure
The size of the trench depends on the size of the ground beam to be installed. For our typical ground beams to an extension an excavation of 600mm deep and 450mm wide is sufficient. Please ring for advice.
There are a number of reasons it may be: A site investigation has highlighted that the ground is unsuitable and un-useable to a depth of more than 2 metres. Removal costs for the excavation of traditional deep trench foundations are too expensive. Foundation trenches are not stable and health and safety, therefore, becomes an issue. There is a high-water table. Where there are soils such as clay that are likely to swell or shrink excessively depending on the amount of water content.

- Our team takes time to comprehensively understand your needs and requirement for the project.
- Our team will pay a visit to the construction site and discuss all the important details.
- Our SCD piling services are of the highest quality along with competitive market rates, thereby always delivering value for money.
The job of the pile is to distribute the weight of the structure evenly. They are placed into the ground using a pile driver. Holding the piles perfectly vertical, this machine hammers each structure into the ground and also acts as a crane.
For a typical house extension, the work can take around 2-3 days, depending on the depth driven and services requested. For more complex projects, contact us for a more specific time frame.
Mini piling in Essex and Colchester is a type of specialist piling that incorporates a specific arrangement and number of driven pile and screw pile varieties. It allows for the expansion or extension of a building, while also safeguarding against ground heave and subsidence. Crucially, mini piling is often a cheaper, faster option than traditional deep trench foundations.
