SOILS TESTING
Tests performed by the GeoSystems geotechnical laboratory include both standard and specialized procedures for determination of physical and engineering properties of soil and rock. All laboratory staff receive test performance training based on American Standards for Testing Materials (ASTM), U.S. Army Corps of Engineers, and GeoSystems' own in-house quality assurance standards. GeoSystems is approved by the U.S. Army Corps of Engineers.

Permeability:

Permeability testing equipment provides both constant and falling head testing conditions. Routine application of high back pressure insures and maintains sample saturation. Gradients can be applied and controlled independently, and permeant can be changed without sample disruption. The lab's equipment is ideally suited for rapid turn-around of permeability test results on clay liners, with preliminary results in 24 hours. Tests include:

ASTM D 5084   Undisturbed Sample in Triaxial Cell
ASTM D 5084   Compacted Sample in Triaxial Cell
            -             Permeability consolidation in oedometer triaxial cell
ASTM D 2434   Permeability Test in Fixed Wall Permeameter
ASTM D 2434   Permeability Test in 12 inch Fixed Wall

GeoSystems uses a state-of-the-art "closed loop, constant volume, variable head" triaxial permeameter system. Triaxial permeameter testing is recommended by the New Jersey Department of Environmental Protection (NJDEP) and the U.S. Army Corps of Engineers (COE) for testing clay soils. When evaluating the permeability coefficient of drainage materials such as sands or gravel, the laboratory conducts tests in accordance with ASTM D 2434. GeoSystems designed its permeameters with over-sized ports and tubing to accommodate high permeant in-flow and out-flow and minimize hydraulic head losses. A "Mariotte tube" controls hydraulic gradient and maintains it to a minimum (usually less than 5) to reduce the migration of soil particles.
