With over 10 years’ experience in the rail industry, Gateway Drainage Services have delivered a vast array of drainage projects on time and in budget with no adverse effect of the operational railway. From UV Lining, Robotic cutting, Hydro cutting, pipe laying, catch pit installation, jetting and CCTV surveys. Our list of services is not only all-encompassing, it’s always growing as we look for initiative ways to deliver projects more cheaply and efficiently including trenchless technology. Trenchless Technology is the science of installing, repairing, maintaining or renewing underground pipes, ducts and cables using techniques that minimise or eliminate the need for expensive and time consuming excavations. The use of such techniques has a reduced environmental impact when compared to other methods, decreased on site costs and at the same time provide efficient alternatives to traditional open cut methods of installation, renewal or repair.
