CMT Engineering Inc. offers permeability testing in unsaturated soils to determine in-situ infiltration and/or field saturated hydraulic conductivity rates. The in-situ permeability testing can be completed in a test pit or down boreholes up to depths of 30 feet. The down borehole method allows for rate determination deep below the ground surface without creating a large, accessible excavation.
Applications for this testing include determination of infiltration rates and overall feasibility of the infiltration of clean run off water for proposed infiltration galleries for residential, commercial and industrial developments. Other applications include compacted clay liner permeability verification and T-Time determinations.
