Mesh Waterproofing Membrane

PermaSEAL 8 Plaster Membrane is a high quality basement wall waterproofing membrane. It benefits from a mesh welded to the surface to allow for direct rendering or dot and dab finishing. PermaSEAL 8 Plaster Mesh is one of the toughest and thickest wall memrbanes on the market today. It is made from 0.65mm high density polyethylene meaning it can withstand everyday site impact damage.

Installing a mesh membrane

PermaSEAL Plaster Membrane is fixed to the basement wall with either PermaSEAL Quick PlugsPermaSEAL Plaster Plugs or PermaSEAL Brick Plugs. It is important that the plugs used are sealed either with Brick Plug Sealing Washers or PermaSEAL Butyl Rope wrapped around the head of the plug before hammering home.

To fix PermaSEAL 8 Plaster Membrane to the wall you will require approximately 15 plugs per m² (300 per roll). Fixing centres internally must not be greater than 250mm horizontally or vertically. On curved or uneven surfaces, closer fixings should be used.

Jointing mesh membranes

Jointing of PermaSEAL 8 Plaster Mesh is achieved by overlapping two membranes and interlocking the studs from the original piece into the new sheet. The overlap should be a minimum of three studs. PermaSEAL Jointing Tape is used to achieve a flat joint. Tape the PermaSEAL Tape to the flat area between the last two studs of the previous sheet of membrane with the backing tape still adhered. Carefully remove the backing tape and push the next sheet studs into the previous sheet studs to create the flat joint.

PermaSEAL 8 Plaster Membrane has a 30 year guarantee against deterioration with a life expectancy of at least 50 years (DIN 9001:2000)
