Scope
What we test in Washington County
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 Washington County
Washington County is one of the fastest-growing counties in the United States, and the construction pace along the St. George corridor reflects that directly. Residential subdivisions, commercial pads, and infrastructure projects are going vertical on desert soils that can vary sharply in bearing capacity, expansiveness, and moisture sensitivity — characteristics that make systematic materials testing a project-management necessity, not an afterthought. Concrete work here also faces a demanding thermal environment: high summer temperatures accelerate hydration and compress the window for compliant placement, while cooler desert nights in shoulder seasons can affect early-strength gain. Our firm dispatches certified field technicians to Washington County through our Las Vegas regional hub, providing ASTM-compliant testing of concrete, aggregate, and soil from early earthwork through structural concrete placement — backed by a laboratory operating under a documented quality system and reporting built to hold up in the field and on the record.
Desert soils across the St. George area can include expansive clays, collapsible soils, and caliche-bearing profiles that respond unpredictably to moisture changes — making Proctor baseline testing and in-place density verification especially important for slab and pavement subgrades. High ambient temperatures during summer months require close attention to concrete mix temperature at point of delivery, water-cementitious materials ratio, and evaporation rates, all of which are captured during fresh concrete field testing.
FAQ · Washington County
Washington County summers are extremely hot. How does that affect fresh concrete testing and what do your technicians check at the truck?
ACI 305R sets guidance for hot-weather concreting, and field technicians measure concrete temperature at point of discharge per ASTM C1064 on every load sampled. When temperatures push mix water demand up or accelerate slump loss, those readings become contract-critical documentation. Technicians also record ambient temperature, time of batching, and time of placement to give the engineer of record a complete thermal picture for each set of cylinders cast.
The soils on our Washington County site look reddish and variable. What classification and compaction testing do you perform before we place fill?
Field technicians classify soils in accordance with ASTM D2487 (Unified Soil Classification System) using Atterberg limits and gradation data. Moisture-density relationships are established by ASTM D1557 (Modified Proctor) or ASTM D698 (Standard Proctor) per specification. In-place density is then verified by nuclear gauge per ASTM D6938 or sand-cone per ASTM D1556, giving the compaction curve reference your geotechnical report requires before structural fill lifts are accepted.
Our structural engineer is requiring special inspections under IBC Chapter 17 for a tilt-up building in St. George. Can your technicians fulfill that role for concrete?
IBC Chapter 17 requires that special inspectors be approved by the authority having jurisdiction and hold recognized credentials. Our field technicians hold ACI certifications relevant to concrete field testing and inspection. Concrete special inspection work includes verifying mix design approval, sampling and testing fresh concrete per ASTM C172, casting strength specimens per ASTM C31, and documenting placement conditions — all reported in formats that support the Statement of Special Inspection your project requires.
How fast can a technician be on site in Washington County?
Washington County work is dispatched through our Las Vegas, NV 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 Washington County, UT?
Field work in Washington County is dispatched through the Las Vegas, NV regional hub, about 108 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Washington County projects.
Are the technicians you send to Washington County 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 Utah agencies or owners require state-specific certifications, those are confirmed in the proposal.
