Scope
What we test in Kennebec 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 Kennebec County
Kennebec County's construction environment presents real technical demands. Maine's freeze-thaw cycle — among the most aggressive in the northeastern United States — puts concrete durability under sustained stress, and the county's mix of glacially deposited soils, variable till, and areas of organic material creates compaction and bearing challenges that require verified field data, not assumptions. Seasonal temperature swings also compress usable pour windows and complicate curing conditions. Our firm dispatches ACI- and NICET-certified field technicians from our Boston regional hub to support contractors, developers, and engineers working across Kennebec County. We perform ASTM-compliant fresh concrete testing and cylinder breaks, aggregate gradation and quality testing, Proctor compaction and nuclear density, soil classification, and soil corrosivity testing — all documented under a formal quality system and reported in formats your project file and your engineer of record can rely on.
Glacially derived soils common to central Maine can vary significantly over short distances, making Proctor reference testing and field density verification important on earthwork-intensive projects. Cold-weather concrete placement in Kennebec County requires close attention to fresh concrete temperatures and curing conditions consistent with ACI 306R guidance.
FAQ · Kennebec County
Maine winters often push projects into cold-weather concrete conditions. What testing is involved, and how does it affect the cylinder break program?
During cold-weather placements, fresh concrete temperature is measured at the point of discharge per ASTM C1064. Cylinders must be protected from freezing during the initial 24-hour curing period; field-cured cylinders may also be requested alongside standard lab-cured sets to reflect actual in-place conditions. Results from both sets help the engineer of record make informed decisions about form removal and load application timing consistent with ACI 306R practice.
We're grading a site in Kennebec County that has pockets of organic material. How does that affect your soil testing approach?
Organic soils generally cannot be compacted to reliable bearing capacity and must be identified and removed or managed before structural fill placement. We perform soil classification testing per ASTM D2487, which includes Atterberg limits and gradation, to characterize material encountered. If organics are present, that documentation supports the geotechnical engineer's recommendation for over-excavation or subgrade treatment and protects the contractor's record against future settlement disputes.
What Proctor standard applies to our project, and how does working in Maine affect the testing schedule?
Standard Proctor testing follows ASTM D698 and modified Proctor follows ASTM D1557; which applies depends on your project specification or geotechnical report requirements. In Kennebec County, scheduling Proctor reference tests early in the project is advisable — if borrow material sources change, a new reference test is required. Coordinating sample shipment to the laboratory ahead of active earthwork avoids compaction holds during the short Maine construction season.
How fast can a technician be on site in Kennebec County?
Kennebec 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 Kennebec County, ME?
Field work in Kennebec County is dispatched through the Boston, MA regional hub, about 149 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Kennebec County projects.
Are the technicians you send to Kennebec 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.
