Lanthwaite House, Buttermere

This luxury, state of the art, residential home in the beautiful but very wet Lake District, has a large habitable basement with an indoor swimming pool, changing rooms, and cinema room. Basement specification was for a Grade 3 completely dry habitable living space (BS 8102:1990) However because of the unique way Xypex Admix works & because the structural thickness of the concrete was in excess of 300mm Xypex automatically produced a Grade 4 (BS 8102:1990) ‘Paper Archive’ level of protection.

Xypex Admix was used in over 1200m2 of waterproof concrete in the basement slab, walls, the indoor swimming pool shell and accompanying balance tanks that are all located in the basement.

Additionally Xypex Patch'n Plug and Xypex Concentrate were used to seal the 21 cored penetrations in the pool shell, which house the underwater lights.
