Scope
What we test in St. Tammany Parish
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 St. Tammany Parish
St. Tammany Parish sits on some of the most geotechnically complex ground in the Gulf South. Shallow water tables, expansive clays, and the residual effects of coastal lowlands mean that soil behavior and concrete performance cannot be assumed — they have to be measured. Add Louisiana's prolonged heat and humidity, which compress workable windows for fresh concrete placement and accelerate moisture-related degradation in structural fills, and the case for rigorous materials testing becomes straightforward. Our firm dispatches ACI- and NICET-certified field technicians to St. Tammany Parish projects through our regional hub network to perform ASTM-compliant testing of concrete, aggregate, and soil from groundbreaking through structural pour. The laboratory operates under a documented quality system, and every report is formatted to support plan review, special inspection programs, and contractor quality records. Whether you are managing a commercial development along the US-190 corridor or a residential subdivision closer to the lake, defensible data starts in the field.
St. Tammany Parish soils commonly include high-plasticity clays and silts that are sensitive to moisture fluctuation, making Proctor compaction standards and in-place density verification critical at every lift. Louisiana's heat and humidity also require close attention to concrete mix temperature, slump, and air content at the point of placement, particularly during summer months when rapid setting can compromise consolidation and early strength gain.
FAQ · St. Tammany Parish
How does the high water table in St. Tammany Parish affect soil compaction testing on my project?
A high or fluctuating water table limits how much moisture can be driven out of fine-grained soils during compaction, which can make it difficult to achieve target densities established by ASTM D698 or D1557 Proctor testing. Nuclear density gauge readings per ASTM D6938 must be interpreted with the existing moisture condition in mind. A qualified technician will flag when field conditions are pushing a fill material past its practical compaction range, allowing your team to make timely decisions about over-excavation, stabilization, or material substitution.
What soil classification testing is typically required before we begin earthwork on a St. Tammany Parish site?
Pre-construction soil classification typically involves Atterberg limits testing per ASTM D4318, grain-size analysis per ASTM D6913 or D7928 for fine-grained fractions, and moisture-density relationship testing. In St. Tammany Parish, where high-plasticity clays are common, classification data directly informs subgrade preparation decisions, fill acceptability criteria, and whether lime or cement stabilization is warranted. Results are reported with USCS classification per ASTM D2487 and referenced against your project geotechnical specifications.
Louisiana summers are brutal. How does hot weather affect concrete cylinder sampling and curing on my job site?
ACI 305R addresses hot-weather concreting, and field technicians follow ASTM C31 initial curing requirements strictly in high-temperature conditions. Freshly cast cylinders must be maintained between 60°F and 80°F during the first 24 hours; in Louisiana summer heat, that often requires insulated curing boxes or shaded, temperature-controlled storage on site. Failure to protect cylinders during initial curing can suppress 28-day break results independently of actual in-place strength, which creates unnecessary disputes and potential core-drilling requests.
How fast can a technician be on site in St. Tammany Parish?
St. Tammany Parish work is dispatched through our Houston, TX 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 St. Tammany Parish, LA?
Field work in St. Tammany Parish is dispatched through the Houston, TX regional hub, about 321 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large St. Tammany Parish projects.
Are the technicians you send to St. Tammany Parish 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 Louisiana agencies or owners require state-specific certifications, those are confirmed in the proposal.
