Scope
What we test in Cambridge
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 Cambridge
Cambridge sits on glacially deposited soils — a mix of fill, organics, and variable glaciofluvial deposits overlying bedrock at inconsistent depths — that make subsurface conditions genuinely unpredictable from block to block. Add Massachusetts' wide temperature swings, which compress and extend concrete placement windows throughout the year, and the density of institutional, life-sciences, and mixed-use construction demanding tight specification compliance, and the stakes for materials testing are real. Our technicians, dispatched from a hub three miles away in Boston, perform ASTM-compliant testing on concrete, aggregate, and soil at every project phase — from Proctor compaction curves and subgrade verification through fresh concrete testing and cylinder breaks. The laboratory operates under a documented quality system. Reports are prepared for third-party review, special inspection programs, and owner QA audits. Whether you're working under a geotechnical specification with strict density requirements or a structural concrete spec tied to ACI 318, we deliver results that are clear, documented, and defensible.
Cambridge's near-surface soils frequently include historic fill and soft organic material that can produce inconsistent compaction results and require careful lift-by-lift density verification. Seasonal temperature extremes — cold winters with extended freeze risk and humid summers — make concrete placement temperature monitoring under ACI 305R and ACI 306R a practical necessity on many local projects.
FAQ · Cambridge
Cambridge has a lot of historic fill near the riverfront. How do you handle compaction testing on variable or suspect fill material?
When fill composition is inconsistent, we establish a reference density using ASTM D698 or D1557 on representative samples, then verify field density lift by lift using nuclear gauge methods per ASTM D6938 or sand cone per ASTM D1556. If material type changes significantly across the site, additional Proctor tests may be warranted to maintain a valid reference density for each fill zone.
Massachusetts winters can push concrete placement temperatures below ACI limits. What field testing do you perform to document cold-weather compliance?
During cold-weather placements, our ACI-certified technicians measure and record fresh concrete temperature per ASTM C1064 at the point of discharge. That data, combined with slump, air content, and unit weight results, provides documentation that the mix met project temperature limits at time of placement — supporting compliance with ACI 306R cold-weather concreting provisions referenced in your specification.
Life-sciences and institutional projects in Cambridge often require early-age cylinder break data. What break schedules are available?
Cylinders are cast per ASTM C31 and can be scheduled for breaks at 1, 3, 7, 28 days, or any project-specified age. Compressive strength testing follows ASTM C39. Early-age breaks at 1 or 3 days can provide useful trend data for form-stripping or post-tensioning decisions, though 28-day results remain the standard acceptance criterion under ACI 318.
How fast can a technician be on site in Cambridge?
Cambridge work is dispatched through our Boston, MA 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 Cambridge, MA?
Field work in Cambridge is dispatched through the Boston, MA regional hub. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Cambridge projects.
Are the technicians you send to Cambridge 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 Massachusetts agencies or owners require state-specific certifications, those are confirmed in the proposal.
