Scope
What we test in Caddo 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 Caddo Parish
Caddo Parish sits in the Red River lowlands of northwest Louisiana, where expansive clays, high groundwater tables, and a humid subtropical climate create real challenges for foundation design, earthwork, and concrete placement. Seasonal heat and humidity accelerate concrete set times and demand careful attention to water-cement ratios and curing — while the region's soft, plastic soils require thorough compaction verification before any structural load is applied. Our firm provides ASTM-compliant construction materials testing across Caddo Parish, covering fresh concrete testing and cylinder breaks, aggregate gradation and quality, Proctor and nuclear density compaction testing, soil classification, and soil corrosivity evaluation. Technicians holding ACI and NICET certifications are dispatched on a scheduled or project-based basis, and all laboratory work runs under a documented quality system. Reports are written to be defensible to engineers, owners, and inspectors — clear on method, result, and specification compliance.
The clay-rich soils common to the Red River floodplain in Caddo Parish are prone to shrink-swell behavior and low bearing capacity, making moisture-density relationship testing (ASTM D1557 or D698) and in-place density verification critical steps before paving, foundation, or fill work proceeds. Northwest Louisiana's extended hot, humid summers also compress the window for ambient-temperature concrete placement and make post-pour curing monitoring a practical concern on larger pours.
FAQ · Caddo Parish
Caddo Parish soils are notoriously expansive — what soil tests should I be requiring on a commercial site here?
At minimum, specify Atterberg limits (ASTM D4318) and soil classification (ASTM D2487) to characterize plasticity and shrink-swell potential. Moisture-density testing per ASTM D1557 or D698 establishes the compaction target, and in-place density testing using a nuclear gauge (ASTM D6938) confirms field compliance. For sites with deep fill or poor native material, hydrometer analysis (ASTM D7928) can further define fines content and behavior.
How far out do I need to schedule a technician for a concrete pour in Shreveport or Bossier City?
Coverage for Caddo Parish is dispatched through our Dallas regional hub, approximately 178 miles away. We recommend scheduling at least 48 to 72 hours in advance for routine concrete field testing visits to confirm technician availability and travel logistics. Project-based standing schedules for larger jobs can reduce lead-time pressure. Contact the dispatch team to set up recurring coverage aligned to your pour calendar.
Louisiana summers are brutal — does heat affect how concrete cylinders need to be handled in the field?
Yes. ACI 305R addresses hot-weather concreting, and field cylinder handling is directly affected. Cylinders must be stored in insulated curing boxes immediately after casting to prevent thermal shock and moisture loss, particularly when ambient temperatures exceed 90°F. ASTM C31 governs initial curing requirements — cylinders held outside those temperature bands can yield non-representative breaks. Our technicians carry appropriate field curing equipment and document ambient and concrete temperatures at time of casting.
How fast can a technician be on site in Caddo Parish?
Caddo Parish work is dispatched through our Dallas, 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 Caddo Parish, LA?
Field work in Caddo Parish is dispatched through the Dallas, TX regional hub, about 178 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Caddo Parish projects.
Are the technicians you send to Caddo 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.
