Construction Materials Testing in Houston, TX
Houston construction runs on fill placed over soft, high-plasticity Gulf Coast clays, which makes density and moisture control the difference between a slab that performs and one that moves. Our technicians cover the Houston metro daily with calibrated nuclear gauges, concrete field kits, and same-day scheduling for pours and earthwork. Cylinders come back to a laboratory operating under a documented quality system, and reports are issued fast enough to keep placement schedules moving. From Beltway 8 tilt-wall to inside-the-loop mid-rise, the testing scope is matched to the project specification, not padded past it.
Expansive Beaumont and Lake Charles formation clays dominate much of the metro; select fill verification and moisture conditioning checks are routine requirements on commercial sites.
- Fresh concrete field testing: sampling (ASTM C172), slump (C143), air content by pressure and volumetric methods (C231, C173), unit weight and yield (C138), temperature (C1064), and cylinder and beam casting (C31)
- Hardened concrete laboratory testing: compressive strength of cylinders (ASTM C39) with unbonded caps (C1231), flexural strength of beams (C78), drilled cores (C42), and petrographic examination (C856), cured per ASTM C511
- Aggregate testing: sampling (ASTM D75), sieve analysis (C136), minus No. 200 by washing (C117), coarse and fine specific gravity and absorption (C127, C128), unit weight and voids (C29), LA abrasion (C131), and stockpile moisture (C566)
- Soil compaction and earthwork: standard and modified Proctor (ASTM D698, D1557), soil-cement moisture-density (D558), oversize correction (D4718), and in-place density by nuclear gauge (D6938)
- Soil classification and index testing: sieve and hydrometer gradation (ASTM D6913, D7928, D422), fines content (D1140), Atterberg limits (D4318), moisture content (D2216), specific gravity (D854), and USCS classification (D2487)

FAQ · Houston
Can you cover multiple Houston pours in one day?
Yes. Metro coverage is dispatched by zone, so concurrent pours across the Houston area can each get a dedicated certified technician with coordinated cylinder pickup.
Do you test select fill for Houston commercial pads?
Yes — gradation, plasticity index, Proctor, and in-place density testing are bundled so select fill acceptance is documented lift by lift.
