Premseal 100 Self-Adhesive Tanking Membrane is used primarily as an external tanking membrane when waterproofing below ground structures. In these instances, it should be used in conjunction with PermaSEAL 8 Geodrain Membrane.
Premseal 100 can also be used as a tanking membrane or a self-adhesive damp proof membrane in vertical and horizontal applications.
The self-adhesive membrane is tough and durable, with an overall thickness of 1.5 mm. It is constructed from a cross laminated high-density polyethylene sheeting and a bitumen-polymer adhesive compound.
Installing a Self-Adhesive Membrane
Make sure that the vertical surfaces that you are applying the tanking membrane to have a smooth finish. They must also be free of loose mortar and dust. Brickwork and blockwork should be dry and pointed or rendered.
The surface would need to be sealed with our self-adhesive bitumen primer. You then need to allow the primer to dry thoroughly prior to installation.
When installing the self-adhesive membrane make sure you apply pressure to the entire surface of the membrane. This ensures good adhesion. All laps and joints must be a minimum of 150mm and rolled to ensure a continuous watertight bond.
When installing the self-adhesive membrane externally, you should use protection boards or PermaSEAL 8 Geo Drain Membrane. This will protect the membrane from damage during backfilling.
Important Note: Premseal 100 Self-Adhesive Tanking Membrane should not be applied in temperatures below 5 degrees, or in wet or misty conditions.
Premseal 100 Self-Adhesive Tanking Membrane conforms to BS 8102:2009 as 'Type A' Waterproofing 'barrier protection'. The product has BBA certification and is CE approved.
