A series of tests (tensile, bend, chemical, and dimensional) conducted on steel reinforcement bars to verify they meet structural strength and ductility requirements. To ensure the steel skeleton of concrete structures is strong enough to carry loads and ductile enough to bend without breaking (critical for earthquake resistance).
The fundamental first step in responsible construction. It transforms the unknown, variable ground into a known, quantifiable engineering material, allowing for the creation of safe, durable, and cost-effective structures.
A test that measures the force required to pull a rebar or anchor out of concrete, evaluating either the bond strength between steel and concrete or estimating in-place concrete strength to verify bond quality, check embedment effectiveness, test post-installed anchors, or estimate concrete strength.
An in-situ field test where a rigid steel plate is loaded incrementally at the foundation level to measure soil settlement and determine bearing capacity to determine the ultimate bearing capacity, settlement behavior, and modulus of subgrade reaction of soil for shallow foundation design.
A portable, impact-driven in-situ test where a steel cone is driven into the ground by a dropped hammer to measure soil resistance and profile strength with depth to rapidly assess soil strength, estimate California Bearing Ratio (CBR) for pavement design, evaluate compaction quality, and profile shallow subsurface conditions.
The test is usually done for borrow pits to determine its shrinkage or swell and compacted earth fill to determine if compaction effort has been adequately done.
A portable, non-destructive device that measures the surface hardness of concrete by striking it with a spring-loaded mass and recording the rebound distance. To quickly assess concrete uniformity, locate weak or deteriorated areas, and provide an indirect estimate of in-place compressive strength.
