Spanish: pretensar

Italian: presollecitazione, precompresso

A precast concrete pile which is prestressed or post-tensioned to reduce or eliminate cracking caused by the tensile stresses to which piles are subjected during transportation, pile driving, and in service.

French: pieu précontraint

Compressing a concrete member with tensioned cables or bars running through it to achieve higher strength for less weight, and to counteract handling stresses.

French: précontrainte

A precast, prestressed concrete pile where the form is spun as the concrete sets. Spinning results in denser concrete, reduces water cement ratio, and hence increases the concrete strength and durability of the pile.

French: pieu béton filé précontraint
