Scope
What we test in Silver Spring
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 Silver Spring
Silver Spring sits at the edge of the Piedmont Plateau, where weathered crystalline rock transitions to the Atlantic Coastal Plain soils just miles to the south and east. That geology — combined with Montgomery County's active redevelopment pipeline of mixed-use, transit-oriented, and institutional projects — means construction teams regularly encounter variable subsurface conditions, fill of uncertain origin, and schedules that cannot absorb testing delays or disputed results. Maryland's climate adds its own demands: summer heat and humidity compress concrete workability windows, while freeze-thaw cycles through the winter months make early-strength data critical for form-strip and loading decisions. Our Washington, DC regional hub, approximately six miles from Silver Spring, dispatches ACI- and NICET-certified technicians for scheduled field testing and laboratory analysis of concrete, aggregate, and soil. Every result is produced under a documented quality system and delivered in reports written to support your spec compliance, agency submittals, and project record.
Soils in the Silver Spring area can shift within a single site from residual Piedmont materials — often silty or clayey weathered rock — to fill or alluvial deposits, making Proctor calibration and in-place density verification important at each distinct stratum. Maryland's hot, humid summers warrant particular attention to concrete temperature, slump, and air content at point of discharge, as conditions can move a mix outside specification limits between the plant and the pour.
FAQ · Silver Spring
Montgomery County and the City of Silver Spring have active special inspection programs — how do your reports support those requirements?
Our field reports are structured to satisfy IBC Chapter 17 special inspection documentation requirements, recording test identification, location, sample source, and technician credentials on every form. Reports reference the applicable ASTM designation and project specification section, giving the building official and project engineer of record a clear, defensible paper trail for permit closeout and certificate of occupancy submittals in Montgomery County.
We're pouring concrete in July in Silver Spring — what field tests do you perform to catch heat-related issues before they become a deficiency?
At each truck, our technicians measure concrete temperature per ASTM C1064, slump per ASTM C143, air content per ASTM C231, and unit weight per ASTM C138, then cast cylinders per ASTM C31 with attention to initial curing conditions in hot weather. These fresh-property results flag mixes approaching ACI 305 hot-weather limits before placement, giving your team time to reject or condition the load.
Many Silver Spring projects involve demolition and redevelopment of older sites — can you classify soils and identify fill conditions during subgrade work?
Yes. Our technicians collect samples for laboratory classification per ASTM D2487 (Unified Soil Classification System) and ASTM D4318 for Atterberg limits, which together characterize whether material is a competent bearing soil or suspect fill. Proctor curves per ASTM D698 or D1557 are then established for each distinct soil type, providing the density standard against which nuclear gauge or sand-cone field readings are evaluated.
How fast can a technician be on site in Silver Spring?
Silver Spring work is dispatched through our Washington, DC 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 Silver Spring, MD?
Field work in Silver Spring is dispatched through the Washington, DC regional hub, about 6 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Silver Spring projects.
Are the technicians you send to Silver Spring 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 Maryland agencies or owners require state-specific certifications, those are confirmed in the proposal.
