BITUTHENE® 4000
Self-adhesive waterproofing membrane with enhanced bonding characteristics for use with B2 moisture tolerant primer
Product Description
BITUTHENE® 4000 is a flexible, preformed waterproof membrane combining a high performance, cross-laminated, HDPE carrier film with a unique, super sticky, self-adhesive rubber bitumen compound.
Ancillary Products
Primer B2
Primer B2 is used to prepare vertical and sloping surfaces and suspended slabs. It is moisture-tolerant and can be used on “green” concrete or damp-to-touch substrates.
Bituthene LM
Waterproof continuity at angles and at penetrations is provided by Bituthene LM two-component, chemically-curing, liquid-applied waterproof membrane..
Bituthene Protection Board
Damage from following trades and backfill is prevented by Bituthene Protection Boards. Located with BitustikTM 4000 double-sided tape.
Product Advantages
-
Cold-applied — simple application to substrates especially at low temperatures.
-
Suitable for application to “green” concrete — reduces programme schedules.
-
Moisture-tolerant primer system — allows application in damp or marginal weather conditions.
-
Wide application temperature range — excellent bond to self and substrate from -10°C to +35°C.
-
Overlap security — enhanced bond provides additional security.
-
Cross-laminated high density polyethylene carrier film — provides high tear strength, puncture and impact resistance.
-
Flexible — accommodates concrete shrinkage cracks.
-
Gas-resistant — methane, carbon dioxide and radon gas protection in excess of the standard membrane requirements in BRE Reports 211 (radon) and 212 (methane and carbon dioxide).

Bituthene 4000 should be brushed onto the surface 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, using a lap roller to ensure complete adhesion and continuity between the layers. On high walls it may be necessary to batten fix the membrane to prevent slippage.
Repairs
Damaged areas to be repaired by patching with an oversize patch applied to a clean dry surface and firmly rolled.

Installation
At air temperatures below +4°C measures should be taken to ensure that all surfaces are free from ice or frost.All surfaces except those below ground bearing slabs and PREPRUFE® R membranes should be primed with one coat of Primer B2 applied at a rate of approx. 10m2 / L. Bituthene 4000 shall be laid by peeling back the protective release paper and applying the adhesive face onto the prepared surface, free from ice, frost, condensation or any contaminants which could adversely effect adhesion. Bituthene LM to be applied at all internal and external corners, penetrations etc. prior to applying the overall membrane.
