Driven concrete piles are displacement piles where no (or minimal) spoil arises at the surface from their installation. Prestressed concrete piles offer several benefits compared to other driven pile systems. Tensile stresses, which can arise in a pile during driving, can be better resisted due to the prestressing forces, and the pile is less likely to be damaged during handling. Bending stresses during driving are also less likely to produce cracking than in conventional precast concrete piles.
Prestressed pilings are generally less permeable than cast reinforced concrete piles and offer superior performance in a marine environment.
