Scope
What we test in Knoxville
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.

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 Knoxville
Knoxville's construction market spans university expansion, mixed-use infill along its river corridors, and continuing industrial and logistics development across the broader East Tennessee region. The area's variable residual soils — products of weathered shale, limestone, and sandstone — require careful characterization before earthwork begins, and the region's humid climate means concrete placement windows can shift quickly with summer heat or late-season temperature drops. Getting materials testing right from the first lift of fill to the final cylinder break matters on every one of these projects. Our certified technicians dispatch to Knoxville job sites on a scheduled and project-based basis through our Atlanta regional hub, performing ASTM-compliant field and laboratory testing of concrete, soil, and aggregate under a documented quality system. Reports are structured to meet engineer, owner, and agency review requirements — giving every party on a Knoxville project defensible documentation at each critical phase of construction.
East Tennessee's residual soils — derived from the weathering of sedimentary and metamorphic rock common to the Ridge and Valley physiographic province — frequently show significant variability in plasticity and bearing capacity across a single site, making thorough soil classification and Proctor testing especially important before establishing compaction acceptance criteria. Knoxville's warm, humid summers also shorten workable concrete placement windows, and cold snaps from late October through early spring can require monitoring of concrete temperatures in accordance with ACI 306 cold-weather guidelines.
FAQ · Knoxville
What soil classification testing do you perform, and why does it matter on a Knoxville site?
We perform grain-size analysis (ASTM D6913, D7928), Atterberg limits (ASTM D4318), and USCS classification (ASTM D2487). On Knoxville-area sites underlain by residual soils from weathered limestone or shale, plasticity and fines content can shift significantly across short distances. Classification data lets the geotechnical engineer set realistic compaction specifications and flag any material that needs moisture conditioning or replacement before structural fill placement begins.
How do you establish compaction acceptance criteria for fill on a Knoxville project?
We run standard or modified Proctor tests (ASTM D698 or D1557) on representative samples of each fill material to determine optimum moisture content and maximum dry density. Those values become the reference point for every nuclear gauge or sand-cone density test taken in the field. The specification governing your project — typically the project geotechnical report or DOT earthwork spec — determines which Proctor method applies and what percent compaction is required.
Tennessee summers are hot and humid. How does that affect concrete sampling and cylinder curing on our project?
High ambient temperatures accelerate hydration and can cause rapid slump loss between the truck and the point of placement. Our technicians record concrete temperature (ASTM C1064) alongside slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138) at each sample. When temperatures are elevated, ACI 305 hot-weather provisions apply. Field-cured cylinders are protected from heat exposure; standard-cured sets go to the laboratory within the window required by ASTM C31.
How fast can a technician be on site in Knoxville?
Knoxville work is dispatched through our Atlanta, GA 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 Knoxville, TN?
Field work in Knoxville is dispatched through the Atlanta, GA regional hub, about 155 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Knoxville projects.
Are the technicians you send to Knoxville 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 Tennessee agencies or owners require state-specific certifications, those are confirmed in the proposal.
