Scope
What we test in Mount Pleasant
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 Mount Pleasant
Mount Pleasant's construction landscape spans high-humidity coastal residential communities, commercial corridors along US-17, and infrastructure projects crossing tidal creek systems — all on soils that can shift from loose fill near reclaimed land to variably saturated clays a few feet down. In that environment, materials testing is not a formality. Concrete placed in South Carolina's summer heat needs to meet slump, air content, and temperature limits at the point of deposit before cylinders are cast, or strength data becomes difficult to defend. Subgrade conditions change across a single pad, and compaction acceptance based on guesswork creates liability. Our certified technicians — dispatched through our regional hub and scheduled around your project phases — perform ASTM-compliant field and laboratory testing of concrete, soil, and aggregate. Results are documented under a structured quality system and delivered in clear, defensible reports that satisfy engineer-of-record and building department requirements in Charleston County.
Mount Pleasant's proximity to tidal marshes and the coastal plain means fill soils and native clays often present variable moisture conditions and low bearing capacity, making accurate Proctor baseline data and consistent density verification critical before any slab or foundation work proceeds. South Carolina's hot, humid summers create real risk of rapid slump loss and elevated concrete temperatures in the field, so fresh concrete testing must be performed promptly at the point of discharge in accordance with ASTM C172.
FAQ · Mount Pleasant
My project is near a tidal creek in Mount Pleasant — what soil testing should I expect the geotechnical spec to require before foundation work?
Coastal plain soils near tidal areas frequently include soft clays, organic material, and engineered fill of variable quality. Expect the specification to call for soil classification under ASTM D2487, moisture-density relationships (ASTM D1557 or D698), and in-place density verification by nuclear gauge (ASTM D6938) or sand cone (ASTM D1556). Soil corrosivity testing may also be required if utilities or structural elements are buried.
Concrete pours in the Charleston area get hot fast in summer. What field limits apply, and how do you document compliance?
ACI 305R identifies 90°F as a commonly specified maximum concrete temperature at point of delivery; project specifications may set tighter limits. Our technicians measure concrete temperature per ASTM C1064, slump per ASTM C143, and air content per ASTM C231 immediately at discharge. Time-stamped field data is recorded on each test report, giving the engineer-of-record a documented record of conditions at placement.
How far out does scheduling need to happen for a technician to reach a Mount Pleasant job site?
Mount Pleasant is covered through our Charlotte, NC regional hub. We coordinate scheduled coverage around your project phases — concrete pours, compaction lifts, and aggregate sampling — with advance notice. We do not guarantee same-day response, so sharing your pour schedule or earthwork timeline as early as possible ensures technician availability and avoids delays in testing and acceptance.
How fast can a technician be on site in Mount Pleasant?
Mount Pleasant work is dispatched through our Charlotte, NC 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 Mount Pleasant, SC?
Field work in Mount Pleasant is dispatched through the Charlotte, NC regional hub, about 175 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Mount Pleasant projects.
Are the technicians you send to Mount Pleasant 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 South Carolina agencies or owners require state-specific certifications, those are confirmed in the proposal.
