Scope
What we test in Charleston
Concrete testing services
Fresh concrete sampled and tested at the pour — slump, air content, unit weight, and temperature — with cylinders and beams cast on site and broken in the laboratory on the schedule your specification calls for.
ASTM C172ASTM C143ASTM C231ASTM C173ASTM C138ASTM C1064ASTM C31ASTM C39
Aggregate testing services
Gradation, fines content, specific gravity and absorption, unit weight, abrasion resistance, and stockpile moisture for concrete, base course, and backfill aggregates.
ASTM D75ASTM C136ASTM C117ASTM C127ASTM C128ASTM C29ASTM C131ASTM C566
Soil compaction and density testing
Standard and modified Proctor curves in the laboratory and in-place density by nuclear gauge on every lift, so fill, subgrade, and trench backfill are documented against the specified percent compaction.
Soil classification and index testing
Sieve and hydrometer gradation, Atterberg limits, moisture content, specific gravity, and USCS classification for earthwork acceptance, select-fill verification, and geotechnical reports.
ASTM D6913ASTM D7928ASTM D1140ASTM D4318ASTM D2216ASTM D854ASTM D2487
Soil corrosivity testing
pH and electrical resistivity of backfill for MSE walls, pipelines, and buried structures, reported against the specification limits for metallic and geosynthetic reinforcement.
Special inspection (IBC Chapter 17)
ICC-certified special inspectors for reinforced concrete and soils, reporting to the building official alongside the materials test results, so one agency covers both requirements.

Local conditions
Construction materials testing conditions in Charleston
West Virginia's rugged Appalachian terrain and the Kanawha Valley's mix of residual and alluvial soils create real geotechnical variability that shows up on every project — from hillside cut-and-fill work to riverfront foundation pads. Concrete work here is also subject to meaningful seasonal swings: humid summers push water-cement ratios and set times, while cold winters require close attention to placement temperatures and protection periods. Getting materials testing right in that environment is not a formality — it is a core quality-control function. Our Charleston, WV regional dispatch hub puts ACI- and NICET-certified field technicians on your site for ASTM-compliant testing of concrete, soil, and aggregate. Fresh concrete properties, compressive strength cylinders, Proctor compaction, nuclear density, gradation, soil classification, and corrosivity testing are all covered under a documented quality system, with reports prepared for third-party review.
The Kanawha Valley's residual soils derived from shale and sandstone parent material can vary significantly in plasticity and compaction behavior across short distances, making field density verification and accurate Proctor baselines particularly important on graded sites. Charleston's climate — with freeze-thaw cycles in late fall and early spring — warrants consistent monitoring of concrete placement temperatures and curing conditions in accordance with ACI 306R cold-weather and ACI 305R hot-weather guidance.
FAQ · Charleston
What Proctor method should we specify for fill compaction on a hillside site in the Charleston area?
Method selection depends on the predominant grain size of the fill material. ASTM D698 (Standard Proctor) and ASTM D1557 (Modified Proctor) cover the two most common compactive effort levels. For coarser or mixed Appalachian residual soils, your geotechnical engineer of record should designate the appropriate method and target relative compaction percentage in the project specifications before field density testing begins under ASTM D6938 or ASTM D1556.
How do you handle concrete cylinder curing when temperatures drop in late fall or winter on a Charleston project?
Field-cured and standard-cured cylinders are both options under ASTM C31. For cold-weather pours, initial curing temperature of cylinders must be maintained between 60°F and 80°F for the first 24 hours. Our technicians document ambient and concrete temperatures at time of sampling, note any protection measures in place, and flag conditions relevant to ACI 306R requirements so the record is defensible if strength results are questioned later.
Can you perform soil classification testing to help our geotechnical engineer characterize Kanawha Valley fill or residual soils?
Yes. Our laboratory runs Atterberg limits (ASTM D4318), particle-size analysis by sieve (ASTM D6913) and hydrometer (ASTM D7928), and moisture-density relationships to support USCS or AASHTO classification. These tests give the geotechnical engineer of record the data needed to assign appropriate compaction specifications and assess suitability of on-site or import fill material before earthwork proceeds.
How fast can a technician be on site in Charleston?
Charleston work is dispatched through our Charleston, WV regional hub. Scheduled visits are set up by phone at (346) 420-5425; multi-day placements and full-time project assignments are scheduled through a proposal request.
Which office covers materials testing in Charleston, WV?
Field work in Charleston is dispatched through the Charleston, WV regional hub. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Charleston projects.
Are the technicians you send to Charleston certified?
Yes. Concrete technicians hold ACI Concrete Field Testing Technician Grade I; soils and laboratory technicians hold NICET Construction Materials Testing certifications; special inspection is performed by ICC-certified special inspectors. Where West Virginia agencies or owners require state-specific certifications, those are confirmed in the proposal.
