transient dynamic response methods to evaluate pile length, continuity and structural anomalies in pre-cast and cast-in-situ concrete piles. The team also performs light weight deflectometer testing to measure surface stiffness, deformation and compaction characteristics of subsoils, granular layers and backfill materials. These services support the design of road pavements, parking and loading areas, temporary foundations, crane working platforms and deep foundations, and provide data for engineering verification and compliance decisions.
