Jun 16, 2019· Pile driving is often a cost-effective and time-efficient method of driving support posts (piles) into the earth. But because you're working with soil and other hidden features in the earth, there is an element of the unknown, and things don't always go as planned. Whether you are driving concrete, steel, or wood piles, any number of problems are common.
The cost for secant piling typically exceeds that of deep soil mix, sheet pile or similar watertight shoring systems; however, the versatility offered by secant piling allows effective construction through highly variable ground profiles ranging from saturated cohesionless soils to hard rock, including advance through cobbles and boulders, and ...

Pile foundations are used in the following situations: When there is a layer of weak soil at the surface. This layer cannot support the weight of the building, so the loads of the building have to bypass this layer and be transferred to the layer of stronger soil or rock that is below the weak layer.

Piles can either be driven into the ground (driven piles) or be installed in a predrilled hole (bored piles or drilled shafts). The construction of bore cast in situ concrete pile consists of 4 primary phases 1.Pile boring, 2.Reinforcement cage lowering, 3.Flushing 4.Pile concreting. Now we will discuss each phase one by one. 1. Pile […]
The spoil is replaced by the pile, hence 'replacement' piles as opposed to displacement piles where soil is forced away by driving or screwing the pile. Bored piles are used primarily in cohesive subsoils for the formation of friction piles and when forming pile foundations close to existing buildings.
