When faced with hard-standing ground, we offer coring services. Our diamond core barrels cut quickly and cleanly and are able to penetrate concrete, brickwork and rebar. These are deployed from either the rig or through the use of out separate Hilti diamond concrete coring drill. With both methods, we can achieve depths of up to 800mm, through the use of extension bars and are able to offer barrel sizes ranging from 100mm to 350mm depending on the client's needs.
