The works were undertaken At Arpley Landfill site located in Warrington. The works comprised the installation of 118,500m2 of 1mm LLDPE and HDPE (25,000m2 LLDPE and 93,000m2 HDPE). The site was an historic disposal location for the Manchester ship canal dredgings. The silts and dredgings are now utilised as the restoration soils on the site. This in itself poses many challenges due to their high moisture content and silty nature. The 100,000m3 of soils were required to be hauled circa 2km from point of excavation to capping location, which results in several haul roads having to be constructed and managed throughout the project.
The site is located in close proximity to several housing estates so it was of paramount importance to the client that DXI liaised with the leachate and Gas teams to ensure minimal infrastructure was removed during the capping this involved working next to live gas and leachate infrastructure on a daily basis.
The capping system comprises:-
• 300mm thick regulating layer (site won dredgings).
• 1mm LLDPE and HDPE double textured welded geomembrane cap.
• The geomembrane cap is overlain by 1200mm thickness of restoration soils.

I have arrived on the Ulverston site for PM Group as a Health & Safety Advisor, in building 11. Last Thursday I had an issue, that was not getting sorted for me, I was close to going for lots of beers. For one reason or another the DXI Lads came to me and said they would take care of it for me.
It wasn’t a small job by any means, it completely took me back, that it wasn’t even their job to do, the flexibility they showed and willingness to help, with a smile on their face I might add.
