Protecto Wall is a self-adhering sheet waterproofing
membrane system designed to prevent water vapour
penetrating through basement retaining walls. Protecto
Wall consists of a tough fabric reinforcement laminated
between two layers of aggressive adhesive membrane.
Protecto Wall is tacky on both sides of the membrane
providing adhesion to the substrate and an adhesive face
to hold the protection board in place. Protecto Wall is used
in conjunction with Protecto Wrap Detail Tape, JS160 H
Mastic and Protecto Wrap Primer. It will adhere to
concrete, timber, steel, polystyrene and fibre cement
sheeting to provide a durable water vapour barrier.
Install of the ProtectoWall membrane must be done by Marshall Innovations
Limited trained & approved installers.
All surfaces to receive the membrane shall be smooth, clean &
free from any defects or irregularities that may affect adhesion or damage the
