A secondary waterproofing layer was achieved by lining the inside face of the retaining wall with Platon P8 – a BBA certified cavity drain membrane manufactured from HDPE. Because of the suspended concrete block and beam floor construction, the P8 was taken down to the foundation without the need for any additional drainage channels. The internal application of Platon P8 membrane enabled a Grade 3 dryness level to be achieved.
After completion of all the waterproofing works, Triton Systems signed off a Certificate of Completion and Watertight Homes Ltd provided the client with a 10 year insurance backed guarantee.
