High Pressure Water Jetting has many uses within the Industrial Services sector, from graffiti removal, surface prep, de-scaling tube bundles, tank cleaning, cutting of sewage screenings, clearing blocked drains, moss and seaweed removal, amongst many other applications.
The fleet of HPWJ Units in Enviro-Clean range from standard HP Jetting pumps rated from 2500psi up to 10,000psi and produced by Harben. The Harben jetting pump is widely regarded as being one of the most efficient and reliable pumps on the market today and has the ability to cover all types of work mentioned above due to the flexible nature of its design.
All Enviro-Clean operators are trained in the use of HPWJ and meet the requirements set out by the HPWJ Association, whom we are members of.
A recent project saw us complete the annual cleaning of the Charing Cross Tunnel in Glasgow. The Tunnel is located on the busy City Centre interchange section of the M8 and is operated by Scotland TranServ, the joint venture between Balfour Beatty and Mouchel.
Completed in 1972, the Tunnel was the final link which brought together all the major routes on the West Coast of Scotland that converged on the City Centre. This allowed travellers quick access from route to route. The Tunnel now allows the easy movement of over 150,000 vehicles per day, way in excess of the original figures produced in 1961. Back then, this section of the M8 was designed originally as a ring road for Greater Glasgow, but today it is the main arterial route from Edinburgh to the West Coast and beyond.
Given the extremely high levels of dirt and grime which come from the 150,000 vehicles and stick to the tiled walls of the Tunnel, a heavy duty degreaser is required to be sprayed on and left to soak in and loosen the greasy surface. This makes the use of the High-pressure Water Jetting to be more effective and remove more of the grime and engine particulates.
Our transit crane-mounted MEWP allows our Operations Department to schedule our own labour to complete all the work without having to rely on sub-contract companies to provide access solutions for working at height.
The two carriageways of the tunnel cover an area of over 7000m2 and it takes 5 full nights to complete the cleaning of the walls, ensuring that Glasgow’s famous tunnel sparkles again.
