Scope
What we test in Kent 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 Kent County
Kent County sits at the heart of Delaware's growth corridor, where state agency projects, light industrial development along the US-13 corridor, and residential expansion are putting sustained demand on construction schedules. The Coastal Plain soils common to central Delaware — often fine-grained, moisture-sensitive, and variable in bearing capacity — mean that fill placement, subgrade preparation, and foundation concrete all carry real risk if testing is skipped or poorly documented. Our firm dispatches certified field technicians to Kent County project sites for ASTM-compliant concrete, aggregate, and soil testing, with reporting prepared for third-party review. Work is coordinated through our Philadelphia regional hub. Field technicians carry ACI and NICET certifications, and laboratory analysis runs under a documented quality system. From Proctor and nuclear density on earthwork to fresh concrete testing and cylinder breaks on structural pours, every service is tied to a defensible, traceable test record.
Central Delaware's Coastal Plain soils are frequently silty or fine-grained and can be highly sensitive to moisture fluctuations, making compaction curve selection and field density verification critical on any graded site. Concrete placements during Delaware's humid summers and freezing shoulder seasons both carry specification-driven requirements for temperature monitoring and curing that technicians document at the point of placement.
FAQ · Kent County
Kent County has a lot of state-funded roadway and site work — what soil testing does my project likely require for DelDOT or county agency submittals?
State and county agency specifications typically require moisture-density relationship testing per ASTM D698 or D1557, field compaction verification by nuclear gauge per ASTM D6938, and soil classification per ASTM D2487. Plasticity index testing (ASTM D4318) is commonly required for subgrade acceptance. We provide test reports formatted for project documentation and agency review. Confirm the exact specification edition with the agency's project engineer before work begins.
How far out should I schedule a technician for a concrete pour in the Dover area?
Coverage for Kent County is dispatched from our Philadelphia regional hub, approximately 58 miles away. Scheduling at least 48 to 72 hours ahead of a confirmed pour time is strongly recommended to guarantee technician availability. Fresh concrete testing — slump, air content, temperature, and unit weight per ASTM C143, C231, and C138 — must occur at the point of discharge, so pour timing and access details should be confirmed when you schedule.
Delaware summers are hot and humid. What concrete testing requirements apply to hot-weather pours on my project?
ACI 305R addresses hot-weather concreting and establishes thresholds for concrete temperature at discharge. ASTM C1064 governs field temperature measurement. When ambient and material conditions approach specification limits, technicians document concrete temperature alongside standard fresh property tests. If your project specification sets a maximum concrete temperature at delivery — commonly 90°F or 95°F — those readings become part of the acceptance record for each load tested.
How fast can a technician be on site in Kent County?
Kent County work is dispatched through our Philadelphia, PA 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 Kent County, DE?
Field work in Kent County is dispatched through the Philadelphia, PA regional hub, about 58 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Kent County projects.
Are the technicians you send to Kent 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 Delaware agencies or owners require state-specific certifications, those are confirmed in the proposal.
