Bituthene® 2000 Pre-formed Self-adhesive Rubber Bitumen/High ...

Grace Building Envelope SystemsBituthene ® 2000Pre-formed Self-adhesive Rubber Bitumen/HighDensity Polyethylene Damp Proof Membrane.Features•Damp proof - moisture/vapour proof barriercapable of resisting hydrostatic head conditionsup to 5 metres.Flexible - accommodates minor settlement andshrinkage movement.Cold applied - no heating, simple, low labourcost.Self-adhesive - full continuity at overlaps.Factory controlled thickness - no variation bysite labour.Rubber/bitumen - flexibility and resistance tomost dilute acids and alkalis.Preformed film surface - immediate access forsame day screeding.••••••ApplicationsBituthene ® 2000 is a combination of a high densitypolyethylene film and a self-adhesive rubber/bitumencompound. It is supplied in rolls 1 mm thick overall,1 m wide and 30 m long (30 sq metres) and isunrolled sticky side down on to blinded hardcore orstructural concrete slabs. Waterproof joints are madeby overlapping 50 mm and firmly rolling surfaces.Applied to top of concrete slab or blinded hardcore,Bituthene 2000 will provide a moisture/vapour proofbarrier and radon gas barrier.Being factory made, thickness of membraneis constant throughout and is not subjected tovariations by site labour such as occurs with brushapplied materials. Bituthene 2000 is flexible andwell capable of bridging shrinkage cracks in theconcrete.SkirtingBituthene 2000Unbonded screedMoisture/vapour proof barrier at slabs on gradeBituthene 2000 with 50 mm laps onsuspended slab primed with Bituthene PrimerAerofilBituthene 2000Bituthene LMBituthene LMMoisture/vapour proof barrier for suspended slabs

Verticalfaces shall be smooth, regular, dry and free from nailsand primed with one coat of Bituthene Primer appliedby brush or roller, at a rate depending on the porosity ofthe surface and allowed to dry before the application ofthe Bituthene 2000. Brickwork must be flush pointed orrendered to provide a smooth surface. Bituthene 2000shall be laid by peeling back the protective release paperand applying the adhesive face on to the prepared surface.The material should be brushed on to the surface toexclude air. Adjacent rolls are aligned and overlapped 50mm minimum at side and ends and well rolled with a firmpressure using a Bituthene Lap Roller to ensure completedadhesion and continuity between the layers. A guidelineis printed on the membrane. Following the applicationcare should be taken to prevent damage by followingtrades. Damaged areas can be repaired by patching withan oversize patch applied to a clean dry surface and firmlyrolled.Health and SafetyRefer to relevant Material Health and Safety data sheets.Quality AssuranceW.
