The initial lateral load test for piles shall be conducted after 28 days of lateral load test pile casting by obtaining a reaction from the concrete block.

Lateral load test for piles may be carried out by introducing a hydraulic jack with a power pack between the pile and the horizontal support beam or truss. The load increment for lateral load test pile should be 20% of the estimated safe lateral load.

Lateral capacity of these piles depends on the properties of soil. Pile behaves as a transversely loaded beam in case of lateral loads and they transfer lateral load to surrounding soil by means of lateral resistance of the soil.
