Scope
What we test in Lakewood
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 Lakewood
Lakewood sits at the edge of the Front Range, where construction projects contend with expansive and variably compressible soils, dramatic freeze-thaw cycles, and concrete placement windows narrowed by high-altitude temperature swings and afternoon weather. A failing compaction lift or an out-of-spec concrete mix discovered after the fact can mean costly rework, schedule delays, and disputes that stall a project in a tight regulatory environment. Our construction materials testing service brings ASTM-compliant field and laboratory testing to Lakewood projects — fresh concrete sampling and cylinder fabrication, aggregate gradation and quality, Proctor compaction curves, nuclear density gauge testing, soil classification, and soil corrosivity evaluation. Technicians hold ACI and NICET certifications. The laboratory operates under a documented quality system. Coverage is dispatched through our Denver regional hub, roughly five miles from Lakewood, with scheduling coordinated around your pour schedule, lift sequence, and submittals.
Colorado's Front Range soils frequently include clays with expansion potential and granular fills that respond sharply to moisture variation, making accurate Proctor moisture-density relationships and field compaction verification critical before placing flatwork, foundations, or pavements. High-altitude afternoon temperature drops and strong sun exposure can affect concrete workability and set time, reinforcing the need for timely fresh concrete testing at the point of placement.
FAQ · Lakewood
Colorado winters can push concrete placement into cold-weather conditions — what testing is performed to verify mix performance during those pours?
During cold-weather placements, technicians measure fresh concrete temperature alongside slump (ASTM C143), air content (ASTM C231), and unit weight (ASTM C138) at the point of discharge. Cylinder sets are fabricated per ASTM C31 and protected from freezing during initial curing. Results document whether the mix and placement conditions met ACI 306 cold-weather requirements — providing defensible records if curing adequacy is later questioned.
How do you establish the correct compaction standard for the fill material being used on my Lakewood site?
We run a Standard or Modified Proctor compaction test — ASTM D698 or ASTM D1557, respectively — on a representative sample of the fill material. The resulting moisture-density curve establishes the maximum dry density and optimum moisture content that field nuclear gauge readings are then compared against. Selecting the correct Proctor method matters: D1557 is common for pavement subgrade and structures where higher load is anticipated.
Lakewood projects often involve Jefferson County or CDOT review — can your reports support those agency submittals?
Reports identify the applicable ASTM test method, sample location, test date, specification requirement, and pass-or-fail status in a clear, consistent format. That structure is designed to support geotechnical engineer review, project record submittals, and third-party agency review. We do not prepare agency-specific forms on your behalf, but the data the reports contain is formatted to be directly usable in those submittals.
How fast can a technician be on site in Lakewood?
Lakewood 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 Lakewood, CO?
Field work in Lakewood is dispatched through the Denver, CO regional hub, about 5 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Lakewood projects.
Are the technicians you send to Lakewood 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.
