Construction Materials Testing in Columbia, SC

Columbia sits on the fall line, and its earthwork does too: Piedmont residual clays through the north of the metro giving way to coastal plain sands through the south, sometimes on the same project. The materials program follows the transition, Proctors matched to clay or sand as actually placed, density per ASTM D6938 with moisture discipline on the clays and gradation attention on the sands, and base course verification where the sandy subgrades demand confinement to perform. Concrete runs the full scope per ASTM C172, C143, C231, C1064, and C31 with strength per C39. Coverage for South Carolina work is project-based, proposed from the specification and schedule.

Fall-line sites around Columbia can transition from clay to sand within a single grading plan, and the fill program needs curves and acceptance criteria for both, assigned to where each material actually went.

• Concrete field testing: slump, air content, temperature, and cylinder casting per ASTM C31
• Compressive strength testing of cylinders and cores per ASTM C39
• Soil compaction and in-place density by nuclear gauge per ASTM D6938
• Proctor moisture-density relationships per ASTM D698 / D1557
• Aggregate gradation, quality, and source testing per ASTM C136
