Construction Materials Testing in Sugar Land, TX

Sugar Land builds on some of the most expansive clay in the region, which means the select fill pad under a building is not filler material, it is structure. We test it that way. Gradation, plasticity index, and Proctor establish what the fill is supposed to be, then in-place density testing per ASTM D6938 documents that every lift actually got there. On the concrete side, our technicians handle sampling, slump, air, temperature, and cylinder casting per ASTM C172, C143, C231, C1064, and C31, with cylinders returning to a laboratory that operates under a documented quality system. Fort Bend County inspectors and structural engineers ask for the paperwork. It is easier when the paperwork is already right.

High-PVR Fort Bend clays put unusual weight on select fill acceptance and moisture conditioning. Fill that passes gradation but arrives too dry or too wet is a common and expensive source of rework.

• Concrete field testing: slump, air content, temperature, and cylinder casting per ASTM C31
