System Components

Membrane

BITUTHENE^® 6000 membrane:  heavy duty, advanced, cold applied, flexible preformed waterproofing membrane. The membrane is unrolled sticky side down on to primed concrete slabs or vertical concrete faces. Continuity is achieved by overlapping 50mm and firmly rolling the joint. A guideline is printed on the membrane.

Limitations of Use

• Approved uses only include those uses specifically detailed in this product data sheet and other current product data sheets that can be found at gcpat.com.
• BITUTHENE^® membranes are not intended for any other use. Contact GCP Technical Services where any other use is anticipated or intended.
• BITUTHENE^® membranes are designed where in-service temperatures will not exceed 130 °F (54°C).
• Do not use BITUTHENE^® Mastic to terminate BITUTHENE^® membranes to PREPRUFE^® pre-applied waterproofing membrabe system. Terminations to PREPRUFE^® membrane should only be done with BITUTHENE^® Liquid Membrane.
• BITUTHENE^® membranes should never be installed through load bearing brick/blockwork walls and must be linked with the damp-proof course to prevent extrusion under load.

Safety  and Handeling

Users must read and understand the product label and safety data sheet (SDS) for each system component. All users should acquaint themselves with this information prior to working with the products and follow the precautionary statements. SDSs can be obtained by contacting your local GCP representative or office, and in some cases from our web site at gcpat.com.au.

Storage

• All BITUTHENE^® membranes should be stored upright
• Observe one-year shelf life and use on a first in, first out basis.
• Store in dry conditions between 4.5°C and 32°C.
• Store off ground, under tarps or otherwise protected from rain and ground moisture.

Installation

Temperature

• Apply BITUTHENE^® 3000 membrane only in dry weather and when air and surface temperatures are 5°C or above.
• Where temperatures are above XXXX prime with BITUTHENE^® Solvent Primer
• Where temperatures are above 5ºC but below XXXX prime with BITUTHENE^® Solvent Primer Vertical

Substrate Preparation

Sloping or vertical faces shall be smooth, regular, dry and free from grease and primed with the appropriate BITUTHENE^® Primer with brush or roller. Type and consumption rate of primer  depends on the porosity of the surface. Allowed surface to  dry completely before the application of the BITUTHENE^®. Brickwork and/or blockwork shall be flush pointed or rendered to provide a smooth surface before priming. 

Priming¹

• All surfaces to which BITUTUENE^® 6000 membrane is to be applied require priming prior to installation of the BITUTUENE® 6000 Membrane
• When temperatures exceed XXXºC apply BITUTHENE^® Solvent Primer by brush or roller to the substrate at a coverage rate of 6 - 7m²/L. Allow to dry one hour or until concrete returns to original color.
• In cold weather conditions (below XXXºC apply BITUTHENE^® Solvent Primer Vertical to the substrate by brush or  lamb’s wool roller at a coverage rate of 6-7m²/L). Allow primer to dry one hour or until tack-free.
• Dry time may be longer in cold temperatures. Re-prime areas if contaminated by dust. If the work area is dusty, apply membrane as soon as the primer is dry. In general, priming should be limited to what can be covered within 24-hours
• Do not apply any primer directly onto any BITUTHENE^® membranes.

Note 1: Where surfaces are pourous more than one coat of primer may be required. It is important to check to be sure proper BITUTHENE^® adhesion is being obtained.

Membrane Application

BITUTHENE^® 6000 shall be laid by peeling back the protective release paper and applying the adhesive face onto the prepared surface. A wide floor brush can be used to press across the surface of the BITUTHENE^® 6000 to ensure good initial bond and exclude air. Adjacent rolls are aligned and overlapped 50mm minimum at side and ends and well rolled with a firm pressure to ensure complete adhesion and continuity between the layers. Use a linoleum roller or standard water-filled garden roller less than 760 mm wide, weighing a minimum of 34 kg when filled. Cover the face of the roller with a resilient material such as a 13 mm plastic foam or two wraps of indoor-outdoor carpet to allow the membrane to fully contact the primed substrate. Seal all T-joints and membrane terminations with BITUTHENE^® Liquid Membrane (LM) by the end of the day. Damaged areas to be repaired by patching with an oversized patch applied to a clean dry surface and firmly rolled (see membrane repairs below).

Top Terminations  

Where the membrane will be terminated (on vertical walls) the exposed upper edge of the membrane must be terminated with a K Flashing or a pressure bar. 

Membrane Repair

Patch tears and inadequately lapped seams with the same membrane as used on the surrounding surface. Clean the in place membrane with a damp cloth and completely dry. Slit fishmouths and repair with a patch extending 150 mm in all directions from the slit and seal edges of the patch with BITUTHENE^® Liquid Membrane. Inspect the membrane thoroughly before covering and make all repairs prior to testing, covering or backfilling.

Membrane Protection

Following the application, care should be taken to prevent damage by following trades by using PROTECTBOARD™ spot bonded with Pak Adhesive or a 25mm screed as horizontal protection. Vertical faces to be protected against damage from backfilling and reinforcement by using PROTECTBOARD™ spot bonded with BITUSTIK™ Tape Super Backfill material should be compacted in layers to prevent settlement and dragging forces being transferred to the waterproofing systems.

NOTE: See PREPRUFE^® data sheet for waterproofing under slabs and vertical reverse tanking applications
