PILING INFORMATION

Extensions

When any of the following occur: The excavation for an extension’s foundations approaches the water table The excavation for an extension’s foundations approaches 2.5 metres in depth The foundation trench is collapsing Excavations are undermining adjacent structures   Then piling will probably be a more economical method of providing foundation than trench fill or under-building.  Piles can be concrete, steel, and sometimes wooden columns, which carry all the weight of a building down through poor materials onto good ground.    All piling work is carried out above ground level and  generally requires little or no preparation prior to the arrival of the rig on site.   Advantages of the driven piling method we use for pile installation include: No spoil production and hence no material to remove from the site We use no wet materials; hence it is a clean operation, no need for wet concrete and the associates spillages All our piling machines are much smaller than conventional machines, enabling us to both:   1. Pile very close to and inside buildings, and 2. Travel over lawns and gardens with minimum disturbance. (If lawns are not to be landscaped after construction, we can work on plywood sheets)   For economy, piles are normally less than 6 metres apart.  If the existing foundation of the house is suitable, conservatories or extensions can be supported between the existing walls and 2 or more piles. Often to minimise disturbance to the existing structure the extension will be wholly sitting on new piles, with some driven close to the wall rather than put extra load on the existing foundations.   The ground beams that then span between the piles are like ordinary foundations, but with steel reinforcement.
