Usage

VisqueenPro Single Sided Tape is used to seal lap joints on damp proof membranes. It can be used internally and externally and is suitable in compressed load applications. The tape can also be used for patch work - when membranes are punctured - and sealing around pipe penetrations.

To be used in conjunction with VisqueenPro Double Sided Jointing tape which bonds the membranes together.

Storage and handling

Store in warm, dry and clean environment in its current packaging. The tape should not be exposed to long periods of ultraviolet light. In very cold weather, prior to use ensure that the material is stored in warm conditions above 5°C.

Preparation

Ensure all surfaces are clean and dry. The membrane joint surfaces should be dry and free from contamination such as dust or sand. Ensure the surface and working area is not water logged. Avoid areas of unsupported jointing.

Installation

Jointing - Apply VisqueenPro Double SIded Jointing tape tape to the lap area of the laid sheet starting approximately 50mm from the membrane edge. Apply pressure to the tape to ensure the tape has adhered to the membrane. Remove quick release paper from the tape and overlap the adjoining membrane by minimum 150mm. The membrane lap joints should then be sealed using the VisqueenPro Single Sided Jointing tape lap tape. Once the tape is applied, the completed lap should be well rolled with frm pressure to ensure a complete seal joint has occurred, and continuity with the adjacent sheet has been achieved.

If the membrane is punctured or perforated a patch of the same material should be lapped at least 150mm beyond the limits of the puncture and bonded with Visqueen Pro Double Sided Jointing Tape and sealed with the Pro single sided tape.

Airtight seals should be formed around all service entry points. Visqueen preformed Top Hat Units should be used for sealing service entry pipes. The base of the top hat and the upstand should be bonded using VisqueenPro Double Sided Jointing Tape and sealed with VisqueenPro Single Sided Tape. The upstand should be secured with the supplied jubilee clip.

Usable temperature range

It is recommended that VisqueenPro single sided jointing tape and other system components should be used above 5°C.
