Scope
What we test in Lake 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 Lake County
Lake County sits at the southern end of the Chicago metropolitan region, where heavy industrial development, intermodal logistics facilities, and large-scale residential construction place demanding requirements on the soils, concrete, and aggregate that go into every project. The glacially deposited soils common to northwest Indiana can vary significantly in bearing capacity and compressibility across short distances, making field verification more than a formality — it is a project risk-management tool. Environmental and municipal agencies in the region routinely require documented test data before approving fills, foundations, and pavement sections. Our firm dispatches certified field technicians to Lake County from our Chicago regional hub to perform ASTM-compliant testing of fresh and hardened concrete, aggregate quality and gradation, soil classification, compaction, and corrosivity. The laboratory operates under a documented quality system, and every report is formatted to withstand scrutiny from project engineers, building officials, and owner representatives.
Glacially derived fine-grained soils in northwest Indiana — including silts and clays with variable plasticity — can be moisture-sensitive and prone to seasonal frost disruption, which affects both compaction windows and the scheduling of concrete placement during spring and late-autumn temperature swings.
FAQ · Lake County
Lake County projects often encounter clay-heavy fill and native soils. What testing do you perform to establish compaction standards for those materials?
For cohesive or mixed soils, technicians run ASTM D698 (Standard Proctor) or ASTM D1557 (Modified Proctor) to establish maximum dry density and optimum moisture content. That baseline is then used to evaluate field compaction via nuclear gauge per ASTM D6938. Where soils are variable across a site — common with glacially derived material in northwest Indiana — multiple Proctor curves may be required to represent each distinct soil type.
Indiana DOT and local agencies sometimes have their own testing frequency requirements. Do your reports satisfy those specs alongside project specifications?
Yes. Reports reference the governing ASTM designation, test date, location, lift number, and in-place density results in a format usable for INDOT submittals and local agency review. If your project specification or the authority having jurisdiction calls out a specific ASTM edition or a minimum testing frequency per lift or per square footage, technicians follow that cadence and the reports document compliance against the stated requirement.
How does cold weather in Lake County affect concrete cylinder handling, and what precautions do you take?
ACI 306R guidance informs cold-weather concrete practice. When ambient or concrete temperatures approach thresholds that could affect initial curing, technicians record fresh concrete temperature per ASTM C1064 and note conditions that may require protected curing. Field-cured cylinders, when specified, are stored in insulated containers on-site. Standard cylinders are transported to the laboratory in padded carriers and maintained at 60–80°F per ASTM C31 initial curing requirements.
How fast can a technician be on site in Lake County?
Lake County work is dispatched through our Chicago, IL 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 Lake County, IN?
Field work in Lake County is dispatched through the Chicago, IL regional hub, about 31 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Lake County projects.
Are the technicians you send to Lake 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 Indiana agencies or owners require state-specific certifications, those are confirmed in the proposal.
