Steel Bearing Piles
Driven steel bearing piles can offer an economic solution in certain circumstances, particularly where soft strata overlay the dense load bearing strata or where a high water table poses problems for concrete cast in-situ systems.
Steel piles have a very high load bearing capacity, which can be further enhanced by the use of high yield steel.
These piles can be in the form of either H piles or interlocking sheet piles. Where sheet piles are used to provide the retaining walls of an underground structure, such as a basement, these piles can be utilised to carry vertical loadings, thus reducing or even elimination the need for any other bearing piles under the structure.
Steel bearing piles are of the low displacement type and therefore there is no soil arising to dispose of, which is of particular benefit in contaminated soils.
When considering environmental impacts steel bearing piles can be extracted at the end of the life cycle of the structure and will result in an enhanced site value as there will be no old foundations that could obstruct future developments.
