Scope
What we test in Fort Collins
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 Fort Collins
Fort Collins sits at the base of the Front Range foothills, where construction teams contend with expansive and variable soils, wide seasonal temperature swings, and a construction calendar compressed by late-spring weather and early-fall frost risk. Those conditions make defensible materials testing more than a paperwork exercise — concrete placed in afternoon heat or near-freezing mornings can fail to reach design strength without proper field monitoring, and subgrade soils that look uniform at the surface often require classification and compaction verification before a slab or pavement section goes down. Our firm dispatches certified field technicians to Fort Collins project sites through our Denver regional hub, providing fresh concrete testing and cylinder breaks, aggregate gradation and quality testing, Proctor compaction, nuclear density gauge testing, soil classification, and soil corrosivity evaluation — all performed to applicable ASTM standards, under a documented quality system, with reports prepared for third-party review.
The Colorado Front Range corridor commonly exhibits soils with swelling potential and variable moisture content with elevation and season change, making proper soil classification, moisture-density relationships, and compaction verification routine project requirements rather than optional steps. Concrete work in the Fort Collins area must also account for freeze-thaw exposure conditions that directly inform mix design review and field air content testing per ASTM C231.
FAQ · Fort Collins
Fort Collins winters can be brutal — what concrete tests are most critical when we're pouring in cold or marginal weather?
In cold-weather conditions, air content (ASTM C231), slump (ASTM C143), and concrete temperature (ASTM C1064) are the most time-sensitive field tests. Temperature must be documented at point of discharge to verify compliance with ACI 306R cold-weather guidelines. Cylinder samples are transported and stored per ASTM C31 to prevent early freezing that would compromise break results.
Our Fort Collins project has a geotechnical report flagging potentially expansive soils — what testing do you provide to support subgrade preparation?
We perform soil classification testing including Atterberg limits (ASTM D4318) and grain-size analysis (ASTM D6913 / D7928) to characterize plasticity and swell potential. Moisture-density relationships are established via standard or modified Proctor (ASTM D698 or D1557), and field compaction is verified with a nuclear density gauge (ASTM D6938) or sand cone (ASTM D1556).
How do you schedule a technician for a Fort Collins site when you're based out of Denver?
Fort Collins project coverage is dispatched from our Denver regional hub, approximately 59 miles away. We coordinate scheduled visits around your pour times, compaction lifts, or inspection windows. We ask that requests be submitted with reasonable lead time; we do not guarantee same-day dispatch. Contact us to discuss your project schedule and set up recurring or milestone-based coverage.
How fast can a technician be on site in Fort Collins?
Fort Collins 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 Fort Collins, CO?
Field work in Fort Collins is dispatched through the Denver, CO regional hub, about 59 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Fort Collins projects.
Are the technicians you send to Fort Collins 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.
