Scope
What we test in Androscoggin 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 Androscoggin County
Construction in Androscoggin County moves through genuine seasonal extremes — hard freezes that arrive early, spring thaw cycles that destabilize subgrades, and a short reliable concrete placement window that makes every pour count. The Androscoggin River valley supports a mix of commercial development, institutional construction, and infrastructure work, much of it on glacially derived soils that can vary significantly in gradation and bearing character over short distances. Getting materials testing right here is not a formality; it is how contractors document that concrete placed in marginal temperature conditions met mix design intent, and how earthwork passes spec on fills that may include variable glacial till. We dispatch certified ACI and NICET field technicians to Androscoggin County project sites, performing fresh concrete testing, cylinder fabrication and breaks, aggregate gradation and quality, Proctor compaction, nuclear density gauge testing, soil classification, and soil corrosivity — all under a documented quality system with reporting prepared for third-party review.
Androscoggin County soils frequently reflect glacial depositional history, meaning fill and subgrade materials can shift between dense till and looser stratified drift within a single project footprint — conditions that make Proctor curve verification and in-place density testing particularly important on any grading or utility work. Maine's extended cold season also requires documented attention to concrete temperature at placement and during curing, consistent with ACI 306R cold-weather concreting guidance.
FAQ · Androscoggin County
We're pouring in October or November in Lewiston — what concrete testing documentation do we need for cold-weather conditions?
Technicians record concrete temperature at point of discharge per ASTM C1064 and slump per ASTM C143 on every load tested. For cold-weather pours, those field measurements combined with dated cylinder fabrication records under ASTM C31 give you and the owner documentation that mix temperature met project specification minimums at time of placement — critical if a dispute arises over curing conditions later in the season.
How do you handle cylinder pickup and transport to the lab when you're dispatching from the Boston hub?
Cylinders are fabricated and initially cured on site per ASTM C31 field-curing requirements, then retrieved and transported to the laboratory under conditions that protect them from shock and temperature extremes. Chain-of-custody is maintained through our reporting system. Projects with break schedules at 7, 28, or other spec-required ages should account for scheduled dispatch logistics when planning pour dates and notification lead times.
Our spec requires aggregate gradation testing on crushed gravel from a local Maine quarry — what does that involve?
Aggregate gradation is performed by sieve analysis per ASTM C136 for coarse aggregate and ASTM C117 combined with C136 for material including fines. Samples are taken from stockpile or conveyor per sampling protocols and tested against the gradation limits in your project specification. If durability or soundness properties are also required, those tests — such as ASTM C131 Los Angeles abrasion — are scoped separately.
How fast can a technician be on site in Androscoggin County?
Androscoggin County 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 Androscoggin County, ME?
Field work in Androscoggin County 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 Androscoggin County projects.
Are the technicians you send to Androscoggin 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 Maine agencies or owners require state-specific certifications, those are confirmed in the proposal.
