Conductor Hole & Mousehole Equipment

United Drilling’s fleet of Ingersoll Rand T4W Drilling Rigs and Watson Augers allows us to bring powerful, versatile, state-of-the-art equipment to every job we perform. Our fleet includes specialized equipment for all types of site and ground conditions. If a complication arises we have customized tooling and a fully staffed shop to solve all problems encountered. United Drilling's rigs are all mounted on rubber tire vehicles; the majority of our equipment does not require any special permitting. This flexibility allows us to move from jobsite to jobsite quickly as there is no downtime while ordering or waiting for permits.

Our support equipment, in combination with our T4W and Watson Auger, is available for every project. This includes a boom truck for transportation and setting of casings, a skid steer to assist in spoils placement, and a 1600 air compressor to increase our speed when drilling through rock.

Mousehole drilling can be provided on the same mobilization, or a separate mobilization as the conductor hole. Pricing is based on the depth and required diameter. United Drilling coordinates the concreting of the mousehole, if required, at completion of drilling or at a later date. Our rigs that are utilized for mousehole drilling have State of Pennsylvania blanket permits, eliminating the downtime associated with ordering and waiting for DOT permits.
