System Components




Storage and Handling


Visqueen Self Adhesive Membrane should be stored vertically under cover in its original packaging. Care should be taken when handling the product in line with current manual handling regulations.



Preparation


All surfaces to which Visqueen Self Adhesive Membrane are to be applied should be free from cavities or projections, have a smooth finish, be dry and free from dust, loose particles and frost. Masonry, concrete or metal surfaces should be primed using Visqueen HP Tanking Primer and allowed to dry thoroughly.

When applying to blockwork or brickwork the joints must be flush pointed or the masonry rendered prior to applying the membrane.

The membrane can be cut with a sharp retractable safety knife.



Installation


Visqueen Self Adhesive Membrane lap joints should be a minimum of 150mm and should be pressed and rollered to form a continuous bond and to ensure watertightness.

At 90 degree changes of direction a Visqueen Axiom UniSeal fillet should be formed prior to membrane installation.

For vertical applications cut the membrane to a suitable length allowing an additional 150mm for laps. Position and peal back release film and apply the self adhesive face to the substrate. Apply pressure to ensure a full bond is achieved. Commence at the top of the wall and work downwards, progressively removing the release film.

For horizontal applications unroll the membrane where required allowing an additional 150mm for laps. Re-roll one half of the membrane and cut release film taking care not to damage the membrane. Roll out the membrane progressively removing the release film.

Use a soft broom over the top of the membrane to ensure full adhesion to the substrate. Repeat for the other half of the roll. Watertight seals should be formed around all service entry points.

Visqueen Preformed Top Hat Units should be used for sealing service entry pipes. If the membrane is punctured or perforated, a patch of the same material should be lapped and bonded at least 150mm beyond the extents of the puncture. The membrane should always be fully protected immediately after it is installed.

When used externally on a retaining wall, the membrane should be protected from backfill with Visqueen TreadGUARD 1500. Alternatively, where external drainage is also required the membrane can be protected with Visqueen Protect and Drain. When forming day joints, the upper edge of the membrane should be adequately secured e.g. bonding onto the top of the retaining wall, or if terminated on a vertical face, the upper edge should be secured with Visqueen Fixing Strip and Visqueen Fixings Pins for Masonry.
