Scope
What we test in Des Moines
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 Des Moines
Des Moines sits on a glacially deposited landscape of loess and till soils that can vary significantly in load-bearing capacity and moisture sensitivity across a single project site. Iowa's wide seasonal temperature swings — from hard freezes that extend well into spring to humid summer heat — create real scheduling and specification challenges for concrete placement and soil compaction work. Developers building the metro's expanding logistics facilities, multifamily housing, and road infrastructure need test data prepared for third-party review and in the field. We dispatch certified technicians to Des Moines project sites through our regional network, performing ASTM-compliant field and laboratory testing of concrete, aggregate, and soil. Fresh concrete testing, cylinder breaks, Proctor compaction, nuclear density, aggregate gradation, soil classification, and corrosivity testing are all covered under a documented quality system, with clear, defensible reports delivered to keep your project moving.
Iowa's glacially derived soils — including moisture-sensitive loess deposits common across the central part of the state — warrant careful Proctor testing and compaction verification before structural fill or pavement subgrade is accepted. Cold-weather concrete placement is a recurring concern in Des Moines, where freezing temperatures can arrive early in fall and persist into late spring, making fresh concrete temperature monitoring and protection plan compliance a practical necessity on most projects.
FAQ · Des Moines
Iowa DOT or city of Des Moines projects require specific compaction standards — can you test to those?
Yes. Field density testing can be performed by nuclear gauge per ASTM D6938 or by sand cone per ASTM D1556, with results referenced against the Proctor maximum dry density established under ASTM D698 (standard) or ASTM D1557 (modified), depending on what your project specification or the governing agency requires. Our technicians document the applicable reference test and acceptance criteria in every report.
How do you handle cold-weather concrete testing during a Des Moines winter pour?
During cold-weather placements, our field technicians record concrete temperature at point of discharge per ASTM C1064 alongside standard fresh concrete testing — slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138). Temperature readings are logged and reported so your team can verify compliance with ACI 306R cold-weather protection requirements and your project specification before cylinders are cast and cured.
Can you perform aggregate testing for a local ready-mix supplier or concrete producer in the Des Moines area?
Yes. Aggregate testing includes sieve analysis for gradation per ASTM C136, material finer than No. 200 sieve per ASTM C117, and aggregate quality evaluation. Results are documented under our laboratory's quality system. Producers can use the data to support mix design development or verify that material from a given source meets project or IDOT specification requirements.
How fast can a technician be on site in Des Moines?
Des Moines work is dispatched through our Kansas City, MO 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 Des Moines, IA?
Field work in Des Moines is dispatched through the Kansas City, MO regional hub, about 179 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Des Moines projects.
Are the technicians you send to Des Moines 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 Iowa agencies or owners require state-specific certifications, those are confirmed in the proposal.
