Scope
What we test in Lewiston
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 Lewiston
Lewiston sits at the confluence of the Androscoggin River valley, where a continental climate delivers hard freeze-thaw cycles, wet spring ground conditions, and construction windows that demand precise timing. Concrete placed during Maine's shoulder seasons — spring and fall — faces early-age thermal risk that only consistent fresh concrete testing can catch before cylinders tell a bad story at 28 days. Glacially derived soils common across central Maine vary in bearing capacity and moisture sensitivity, making Proctor compaction and field density verification essential on any earthwork-dependent project. Our firm dispatches certified field technicians to Lewiston through our Boston regional hub to handle concrete, aggregate, and soil testing on a scheduled or project-call basis. Field work follows applicable ASTM standards; the laboratory operates under a documented quality system. Reports are written to be defensible at the design-team, agency, and contractor level — straightforward documentation that keeps your project moving.
Central Maine's glacially influenced soils can include silty or fine-grained material that is sensitive to moisture changes, making accurate Proctor moisture-density relationships and consistent field compaction verification particularly important during the wet spring construction period. Freeze-thaw exposure class considerations under ACI 318 are relevant for any exterior concrete in Lewiston's climate, and air-entrainment verification during fresh concrete testing is a practical front-line check on durability.
FAQ · Lewiston
How do you schedule technician dispatch to Lewiston from your nearest hub?
Lewiston is covered through our Boston regional hub, approximately 128 miles away. Coverage is coordinated on a scheduled or project-call basis — we work with your superintendent or project engineer to align technician arrival with concrete pours, earthwork phases, or inspection milestones. Advance notice of at least one business day is recommended to confirm availability. We do not promise same-day response for this location.
What air-entrainment and temperature requirements apply to concrete placed during a Maine winter or cold-weather period?
ACI 306R provides cold-weather concrete guidance, and your project specification will define minimum placement and protection temperatures. Our technicians measure fresh concrete temperature per ASTM C1064 and air content per ASTM C231 at every tested load. If readings fall outside specification limits, the technician documents the nonconformance immediately so the contractor and engineer can act before concrete is placed or finishing begins.
Can you perform soil classification testing relevant to Maine DOT or municipal project submittals in Lewiston?
Yes. Laboratory soil classification follows ASTM D2487 (Unified Soil Classification System). Grain-size distribution is performed per ASTM D6913 and, where fines content warrants, hydrometer analysis per ASTM D7928. Atterberg limits follow ASTM D4318. These classifications support geotechnical reports, subgrade evaluations, and fill-material acceptance documentation consistent with the data formats Maine DOT and local agency submittals typically require.
How fast can a technician be on site in Lewiston?
Lewiston 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 Lewiston, ME?
Field work in Lewiston is dispatched through the Boston, MA regional hub, about 128 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Lewiston projects.
Are the technicians you send to Lewiston 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 Maine agencies or owners require state-specific certifications, those are confirmed in the proposal.
