Concrete Core Testing Services in Chennai

Rebound Hammer only tests the outer surface hardness. A Core Test is a partially destructive test that extracts actual concrete from deep inside the structure and physically crushes it in a lab. It provides the most accurate, legally accepted proof of concrete strength.

No. The core diameter is typically small (75mm-100mm). More importantly, we always perform Rebar Scanning first to avoid cutting the steel reinforcement. Once the core is extracted, the hole is immediately packed with non-shrink, high-strength epoxy grout.

If the core strength is significantly lower than the designed grade, our structural engineers will perform a load analysis. If the member is unsafe, we will provide retrofitting solutions (like column jacketing or carbon fiber wrapping) to strengthen the structure.

Costs involve site mobilization, drilling, and NABL lab crushing. It generally ranges from ₹4,000 to ₹7,000 per core, depending on the location and number of cores required.
