LABRATORY TESTING
Our in-house laboratory provides rigorous materials testing and quality assurance services to support construction, design, and regulatory compliance throughout Pennsylvania, Maryland, New Jersey, and Delaware. By combining field inspection, geotechnical insight, and our own in-house soil science laboratory, we deliver a seamless pathway from site to specification by keeping many processes under one roof.
We are equipped to perform a broad suite of tests on construction materials and site samples, delivering reliable data to inform design, quality control, and compliance.
- Compressive strength testing (cylinders, cubes)
- Flexural strength, tensile splitting tests
- Mortar compressive strength
- Grout compressive strength
- Masonry unit absorption, dimensional tolerances (upon request)
- Grain size distribution / sieve analysis
- Atterberg limits (liquid & plastic limits)
- Proctor (standard & modified) and relative density tests
- Specific gravity, absorption, voids, bulk and dry density
- Gradation, moisture content, organic content
- Gradation, bitumen content, binder testing
- Marshall mix design, volumetrics (upon request)
- Compaction curves, density, stability tests (upon request)
- Performance tests (rutting, fatigue, etc.) (upon request)
- Chloride and sulfate content for concrete exposure assessment
- pH, resistivity, permeability for corrosion risk evaluations
- Freeze-thaw resistance, absorption / porosity tests
- Petrographic examination, material condition assessment
- Supplementary lab support for investigations, failure analysis, rehabilitation
- Durability testing: per ASTM protocols (e.g. freeze-thaw, rapid chloride permeability, sulfate)
- Supplementary cementitious material characterization (fly ash, slag, silica fume)
This process includes examining the substrate, evaluating ambient conditions, and reviewing the completed application. Field tests are conducted to measure thickness, density, and bond strength, ensuring the SFRM is correctly applied and meets the required fire-resistance rating.
