Lateral Load Testing evaluates pile performance under horizontal forces caused by wind, seismic activity, soil pressure, or operational loads. It provides critical information about lateral stiffness, deflection, and load-bearing capacity. In Sri Lanka, where infrastructure is often exposed to cyclones or seismic zones, this testing ensures stability and safety.

The test involves installing a lateral reaction system, applying incremental horizontal loads, and measuring lateral displacements and rotations using sensors. The behavior of the pile under load is observed and analyzed against design criteria. Load is applied until the design or ultimate lateral capacity is reached.

Reports provide load-displacement curves, lateral stiffness values, and performance evaluations. This allows engineers to verify pile suitability for horizontal loads, make design adjustments if necessary, and ensure long-term stability of the structure.
