Scope
What we test in York 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 York County
York County's construction landscape spans coastal resort communities, year-round residential neighborhoods, and light commercial corridors — all subject to Maine's demanding freeze-thaw climate and a coastal geology that frequently presents variable glacial till, ledge, and marine-influenced soils within the same project footprint. Those conditions make reliable materials testing more than a compliance checkbox: proper concrete mix verification, accurate soil classification, and compaction confirmation directly affect long-term structural performance when ground conditions shift and when concrete placed in shoulder seasons faces early thermal stress. Our firm dispatches ACI- and NICET-certified field technicians to York County project sites from our Boston regional hub, covering scheduled and project-based testing for concrete, aggregate, and soil under a documented quality system. From fresh concrete testing and cylinder breaks to Proctor compaction and soil corrosivity, every test is tied to the correct ASTM designation and delivered in a report your engineer of record, general contractor, or owner can use with confidence.
Glacially deposited soils across York County can transition quickly between granular outwash and finer-grained material, making soil classification and compaction testing particularly important for earthwork QC. Maine's extended freeze-thaw season also places real demands on concrete placed in spring and fall, where fresh concrete temperature monitoring and protection planning — consistent with ACI 305 and ACI 306 guidance — should be part of any project quality program.
FAQ · York County
We're building a foundation near the York County coast — should we expect soil corrosivity to be a concern for embedded steel or utilities?
Coastal and near-coastal soils in Maine can exhibit elevated chloride content and variable pH levels that accelerate corrosion of embedded metals and utility conduit. Soil corrosivity testing — measuring resistivity, pH, sulfate content, and chloride content — provides the data needed to specify appropriate pipe coatings, concrete admixtures, or protective measures before installation. Results are reported alongside the relevant method references for your engineer to evaluate.
What soil classification methods do you use, and are they sufficient for Maine DOT submittal packages?
We perform classification using ASTM D2487 (Unified Soil Classification System) and ASTM D3282 (AASHTO system), which are the methods most commonly referenced in state and municipal geotechnical specifications. Gradation testing follows ASTM D6913 for sieve analysis and ASTM D1140 for material finer than the No. 200 sieve. Your project engineer or owner's representative should confirm which classification system your specific submittal requires.
How far in advance do we need to schedule a technician for concrete pours in York County?
Technician coverage in York County is dispatched from our Boston regional hub, approximately 78 miles away. We recommend scheduling at least 48 to 72 hours ahead for routine concrete field testing visits to ensure proper routing and technician availability. For projects with recurring pour schedules, establishing a standing dispatch plan at the start of the project typically reduces last-minute coordination and helps keep your inspection log current.
How fast can a technician be on site in York County?
York 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 York County, ME?
Field work in York County is dispatched through the Boston, MA regional hub, about 78 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large York County projects.
Are the technicians you send to York 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.
