G&D developed extensive in-house construction materials testing capabilities in response to the needs of our construction observation services clients. As a result, we have the capability to provide the materials testing services required to ensure all work meets the material specifications on most public works and private sector development projects. Our team is capable of performing a wide range of field construction materials tests on 24 hours notice, or less, in the Charlotte-metro area.
Among the tests we commonly perform are:
- Field density and moisture (nuclear density gauge, sand cone, drive cylinder, modified DCP);
- Soil bearing capacity using the DCP;
- Concrete sampling for compressive strength; slump; entrained air; temperature, as well as
- Asphalt density, thickness, and temperature.
