FOSROC PROOFEX SHEETDRAIN 80 40M2

Uses:
◇ Proofex Sheetdrain 80 is an HDPE cuspated drainage sheet. It is located against buried walls ansd roofs of structures for below ground depths of up to 6mm to provide a filtered, drainage void that will route percolating water away from the structure in conjuction with an effective drainage system.
◇ Proofex Sheetdrain 80 can also be used as protection layer for Type A membranes from physical damage during backfill operations.
◇ It is an effective alternative to traditional stone 'French' drains providing improved drainage performance.
◇ Where directly cast concrete sub-structure walls need to be drained, Proofex Sheetdrain 80 may be used as a lost shuttering liner.
◇ Proofex Sheetdrain 80 provides filtered drainage and enhanced protection when used with Proofex waterproof membranes on reservoirs, podium decks and elevated slabs.
◇ It can be utilised in conjuction with the required ancillaries to provide a gas pressure relief pathway as part of a BS8485 compliant ground gas protection solution.

Advantages:
◇ Cost effective - no need for up to 500mm thick stone drainage layer behind retaining walls
◇ Easy site application
◇ Reduced environmental impact - no need for vehicular removal and transportation of spoil off site and subsequent replacing with expensive stone drainage layer
◇ High flow rate (water and gas)
◇ High impact resistance, HDPE cuspated core with a compressive strength of up to 200kN/m² provides drainage void around structures under backfill and long term loadings
◇ Cost effective alternative to 'French Drains'
