The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density.
Since moving into our current office, the added space has allowed us to develop an in-house soils and construction materials testing laboratory. The ability to store and test soils and construction materials at our facility, in lieu of using a third party laboratory, has greatly decreased the turnaround time for obtaining and reporting test results while reducing the overall cost of these services. We are currently equipped with a walk-in cure room for storing concrete, mortar and grout samples. We also have several lime-water submersion tanks to accommodate compressive strength specimens when necessary. We utilize a Forney, digital readout compression machine to verify the compressive strength of concrete, mortar and grout samples. Our Concrete laboratory is CCRL (Cement and Concrete Reference Laboratory) certified and our Soils laboratory in AMRL (AASHTO Materials Reference Laboratory) certified. Our in-house laboratory equipment and staff meet the standards of excellence set forth by the CCRL and AMRL which ensures our clients will receive concise, accurate test results in a timely manner.
