We know how to help you get the data quickly and effectively reduce assessment costs.

CDS provides geotechnical drilling as a stand-alone service, or in conjunction with environmental assessments as part of environmental construction and Brownfield development.

CDS employs the AMS automatic drop hammer. The auto-drop hammer is a hydraulic system that works on a chain system with adjustable cylinder for easy calibration.  Hammer is operated from an electronic pendant control box. This allows the operator to control the advancement of the sampler while remaining a safe distance from the hammer.

We are experienced using the ASTM Standard D1586 Standard Test Method for Standard Penetration Test (SPT) and Split-Barrel Sampling of Soils.
