Scope
What we test in New Orleans
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 New Orleans
Building in New Orleans means contending with some of the most challenging subsurface conditions in North America. Expansive, high-plasticity clays, organic-rich fills, and a high water table compress and shift under load in ways that can compromise structural performance well before a project reaches occupancy. Above grade, the subtropical climate — long hot summers, significant annual rainfall, and periodic tropical weather — creates concrete placement windows that demand careful attention to water-cement ratios, admixture use, and curing practice. Our construction materials testing services are designed for these conditions. Certified field technicians dispatched through our Houston regional hub conduct ASTM-compliant fresh concrete testing, cylinder fabrication and compressive strength testing, aggregate gradation and quality evaluation, Proctor compaction and nuclear density testing, and soil classification and corrosivity analysis. Every service is backed by a documented quality system and delivered with clear, defensible reports built to support project documentation, pay applications, and regulatory submittals.
New Orleans area soils frequently include soft, compressible clays and organic materials that respond poorly to load without proper subgrade preparation and verification — making Proctor and in-place density testing essential on virtually every earthwork scope. High ambient temperatures and humidity during Louisiana summers can accelerate concrete hydration, making timely fresh concrete testing under ASTM C172 and C1064 critical to capturing representative field conditions.
FAQ · New Orleans
Our project is in the New Orleans metro and uses pile-supported slabs because of soft soils. Do you still perform subgrade and fill testing on these projects?
Yes. Even on pile-supported structures, granular fill placed for utility bedding, slab-on-grade areas, or parking courts typically requires compaction verification. We perform in-place density testing per ASTM D6938 (nuclear gauge) or ASTM D1556 (sand-cone) and compare results against a laboratory-established maximum density from ASTM D698 or D1557, documenting compliance with the project specification.
How does the high water table in the New Orleans area affect Proctor and compaction testing?
A shallow water table can make achieving and verifying target compaction difficult, particularly in cohesive or organic soils. Our technicians establish the moisture-density relationship in the laboratory per ASTM D698 or D1557, then test field moisture carefully during in-place density work. When soils are near or above optimum moisture, we document conditions so the geotechnical engineer of record can evaluate whether additional lifts or drying are required before testing continues.
Louisiana heat is hard on fresh concrete. What tests do you perform to document conditions at placement?
On every fresh concrete visit, technicians record concrete temperature per ASTM C1064 alongside ambient temperature and time of sampling. Slump is measured per ASTM C143, air content per ASTM C231 or C173, and unit weight per ASTM C138. Cylinders are fabricated per ASTM C31, including field-curing documentation. All data is tied to the specific load and placement location, giving you a defensible record if temperature compliance is questioned.
How fast can a technician be on site in New Orleans?
New Orleans 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 New Orleans, LA?
Field work in New Orleans is dispatched through the Houston, TX regional hub, about 318 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large New Orleans projects.
Are the technicians you send to New Orleans 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.
