Mini Piling / restricted access piling
Mini-Piling is a piling solution for restricted access or smaller sites and where noise and vibration may be an issue. It is also particularly useful in areas of variable ground conditions or where structural movements in service must be minimal. Mini-piling equipment can be used for work inside buildings where height is restricted and prevents the use of larger equipment rigs.
Hollow stem piling
Hollow stem piles are constructed with sectional hollow stemmed augers where the ground conditions will not allow normal auger piles, once the depth has been reached grout is then pumped through the centre of the augers to the bottom of the pile, the augers are then extracted whilst the grouting continues to ground level. This piling solution is suitable for wet ground or unstable bores.
A piled raft foundation combines two foundation-building techniques into a hybrid design suitable for specialized circumstances. The raft, or spread, foundation spreads the load of the building across the ground. Think of it as a raft floating on the ground supporting a structure. Piles are columns extending below the ground surface that connect at the top of the building. A piled raft foundation uses both methods to support the building.
Reinforced ground beam
A ground beam is a reinforced concrete beam for supporting walls, joists, at ground level, itself either resting directly upon the ground or supported at both ends by piers. A ground bean is the most common method used to link the piles together.
Traditional and piled underpinning
Underpinning is strengthening the foundation of an existing building or other structure. Underpinning may be accomplished by extending the foundation in depth, so it rests on a more supportive structure and distributes its load across a greater area. Use of piles are common methods in underpinning.
Despite not being visible when the house is complete, the foundations are one of the most important elements of a building project. It is not only essential that you choose the right foundation system for the soil type but also that measurements are made very carefully and as planned.
Strip foundations (or footings)
Strip foundations provide a continuous strip of support to a linear structure such as a wall.
Trench fill foundations are a variation of strip foundations, in which the trench excavation is almost completely filled with concrete.
Rubble trench foundations are a further variation of trench fill foundations, and are a traditional construction method which uses loose stone or rubble to minimise the use of concrete and improve drainage.
A slabs that cover a wide area, often the entire footprint of a building, and are suitable where ground conditions are poor, settlement is likely, or where it may be impractical to create individual strip or pad foundations for a large number of individual loads. Raft foundations may incorporate beams or thickened areas to provide additional support for specific loads.
Retaining walls are relatively rigid walls used for supporting the soil mass laterally so that the soil can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to.
