Barns Croft
The supply and installation of Gas and waterproofing membranes for the prestigious new build, Barns Croft, located in Ampney Crucis.
The Challenge
CCL were employed by Cranatt construction to supply and install a combined gas and waterproof membrane solution to the luxury new build dwelling, Barns Croft, inclusive of a basement and buried roof deck.
A gas characteristic of CS2 was identified within ground report, therefore the solution needed to protect against methane, carbon dioxide and hydrocarbons.
The Solution
Working closely with RIW, CCL supplied and installed RIW’s Structureseal GPT gas/ water resistant pre-applied membrane, prior to other contractors within the project forming the reinforced concrete retaining walls and basement slab.
This was followed by the application of RIW Flexiseal 500HG waterproof coating and protective drainage sheet to the concrete roof decks above the basement areas. Including Sheetseal GR reinforcement, linking onto RIW Structureseal GPT.
In addition to this, CCL supplied and installed RIW’s Cavity Drain Membrane as a second form of waterproofing, including the provision of a mechanical sump pump system.
CCL utilised automated thermal heat welding technology to ensure a robust seal for the joints across the whole system. The entire installation was then verified by a certified independent specialist, in accordance with BS8485:2015+A1:2019, whilst also meeting the requirements of CIRA C735
Client Testimonial
