Scope
What we test in Colorado Springs
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 Colorado Springs
Construction in Colorado Springs sits at elevations generally ranging from about 6,000 to over 7,000 feet, where thin air, intense UV exposure, and wide daily temperature swings create conditions that directly affect concrete workability, set time, and cure strength. Add the region's expansive and variable soils—ranging from clay-rich bentonitic formations to sandy decomposed granite—and the margin for error in materials testing narrows considerably. Structural fills, foundation subgrades, flatwork, and concrete placed during shoulder seasons all need documented, defensible test data to meet project specifications and protect your schedule. Our firm dispatches certified field technicians to Colorado Springs through our Denver regional hub, providing scheduled and project-based coverage for fresh concrete testing, compressive strength cylinder breaks, aggregate gradation and quality, Proctor compaction testing, nuclear density gauge field verification, soil classification, and soil corrosivity analysis. The laboratory operates under a documented quality system, and every report is prepared for third-party review.
Colorado Springs area soils frequently include expansive clays and highly variable native materials that can produce significant plasticity index variation across a single site, making soil classification and Proctor testing critical inputs before any structural fill or pavement subgrade work begins. High-altitude concrete placements also require close attention to ambient temperature fluctuations—both low overnight temperatures in spring and fall and rapid evaporation conditions in summer—which affect fresh concrete performance under ACI 305R and ACI 306R guidance.
FAQ · Colorado Springs
My project is at high elevation in Colorado Springs—do temperature and evaporation conditions affect how you schedule concrete testing?
Yes. At elevations above 6,000 feet, lower atmospheric pressure and low relative humidity accelerate surface evaporation, raising plastic shrinkage cracking risk, while morning or evening pours in spring and fall can approach cold-weather thresholds covered by ACI 306R. Technicians monitor ambient temperature, concrete temperature, and slump at point of placement per ASTM C172 and C1064, and flag conditions that your mix design or project spec requires you to document and act on.
We have soils with high plasticity on a Colorado Springs site. What classification and compaction testing do you perform?
Technicians collect representative samples for Atterberg limits testing per ASTM D4318 and gradation per ASTM C136 and D6913, enabling USCS or AASHTO classification. Proctor curves are developed under ASTM D698 (Standard) or D1557 (Modified), matched to your specification. Field density is verified with nuclear gauge testing per ASTM D6938 or sand-cone per ASTM D1556, with each result compared directly against the established compaction curve for the material on site.
Pikes Peak-area projects sometimes involve decomposed granite subgrades. Does that material behave differently in testing?
Decomposed granite is generally a low-plasticity granular material, but particle breakdown during compaction and variable fines content can cause density test results to differ from what contractors expect from a 'granular' soil. Proctor and field density testing per ASTM D1557 and D6938 remain the required steps. If the specification calls for R-value or CBR for pavement design, we can include that sampling in the same site visit.
How fast can a technician be on site in Colorado Springs?
Colorado Springs work is dispatched through our Denver, CO 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 Colorado Springs, CO?
Field work in Colorado Springs is dispatched through the Denver, CO regional hub, about 63 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Colorado Springs projects.
Are the technicians you send to Colorado Springs 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 Colorado agencies or owners require state-specific certifications, those are confirmed in the proposal.
