Intrusive Site Investigation
ERS adds further value by providing seamless site investigation, supervision and sample handling where required. We aim to represent our clients to the highest possible standard, using the latest techniques to offer a full range of site investigation services. We can advise on the most appropriate use of an extensive range of open hole and cased site investigation plant including rotary flight auger and down-hole hammer techinques including Odex and Symmatrix, all of which we offer on a subcontracted basis. ERS also owns and operates drilling equipment including:
Windowless sampling
Low impact, rubber-tracked percussive rigs capable of recovering high quality samples from depths up to eight metres. Core samples are recovered in plastic tubes, logged by qualified engineers and packed for transit before testing and storage.
Rotary drilling
Our rubber-tracked rig is equipped with adaptations to facilitate rotary open-hole and rock coring and is suitable for rapid drilling to depths of up to twenty metres. This rig is particularly suited for use on narrow access or low clearance sites.
Cable percussive drilling
Our cable percussive rigs enable us to retrieve and log disturbed and undisturbed samples and carry out on-site geotechnical tests, including standard penetration testing (SPT). Low apex height option is available.
