Precast Concrete Piles
Description
Description
Precast piles exertextra strength to resist bending moment during pile pick up, transportation, vertical loads, and bending moment as a result of lateral loads.
MAIN LONGITUDINAL REINFORCEMENT is designed for lifting, handling and pitching. It is also been taken into consideration for contributing to the axial load capacity.
LATERAL REINFORCEMENT in the form of links is provided to prevent shattering or splitting of pile during driving.

General Considerations when Choosing Pile Type
-
Poor quality of upper soil layer
-
Costly soil in construction site
-
To withstandlateral loads (horizontal)
-
To withstanduplift forces
-
Bridge abutment and piers
