BITUTHENE® 3000/3000 HC

Product Description

BITUTHENE® 3000/3000 HC is a high performance, cold-applied, flexible, preformed waterproof membrane combining a special high performance, cross-laminated, HDPE carrier film with a unique self-adhesive rubber bitumen compound.

Product Advantages

• Waterproof — high hydrostatic head resistance
• High density cross-laminated polyethylene film
• Provides dimensional stability
• Provides puncture resistance
• Single layer — simple, reliable, low labour cost with the benefit of site programmed installation
• 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)
• Cold-applied
  • No flame hazard
  • No heating required
• Self-adhesive rubberised asphalt
  • Continuity ensured at overlaps
  • Unique rubber/bitumen formulation allows healing of small punctures
• Factory controlled thickness — no variation by site practices
• Chemically-resistant — provides effective external protection against aggressive environments and ozone attack
• Flexible — accommodates minor settlement and shrinkage movement
• Tanking security — combined flexible membrane and waterstop system for security

Applications

• Basement
• Sub-structures
• Flat decks
• Roof assemblies
• Elevated or grade level podiums
• Plaza decks / Roof gardens / Terraces

Installation

Sub-structure Assembly

Measures should be taken to ensure that all surfaces are free from ice, frost or condensation. Roof slab surfaces must be dry, and free from sharp protrusions, and any hollows to be filled with high strength mortar.

Horizontal and vertical faces must be smooth, regular, dry and free from nails. Prime the horizontal and vertical surfaces with one coat of BITUTHENE® Primer applied by brush or roller at a rate of 6-8sq m per litre depending on the porosity of the surface, and allow to dry completely before the application of BITUTHENE® 3000/3000 HC.

BITUTHENE® 3000/3000 HC should be laid by peeling back the protective silicone release paper and applying the self-adhesive face on to the surface to ensure good initial bond.

Adjacent rolls are aligned and overlapped 50mm minimum at side and 50mm*** at ends, and the overlaps well rolled with a firm pressure using a lap roller to ensure complete adhesion and continuity between the layers.

Following the application and inspection, care should be taken to prevent damage by following trades. As soon as practicable after the application, BITUTHENE® 3000/3000 HC should be protected from exposure to the weather and physical damage using BITUTHENE® protection boards, insulation or HYDRODUCT® drainage composites laid dry.

Any punctured or damaged areas should be cleaned and patched using Bituthene 3000/3000 HC with minimum 50mm laps all around.

Following the application, care should be taken to prevent damage by following trades by using Bituthene protection boards 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 Bituthene protection boards spot bonded with Pak Adhesive.

The junction between the slab and parapet shall have a fillet of Bituthene Liquid Membrane or other acceptable methods placed firmly into position before using 300mm wide reinforcing corner strips of Bituthene 3000/3000 HC placed centrally over the axis of the change of direction.

Always apply Bituthene membrane directly to primed or conditioned structural substrates. Insulation, if used, must be applied over the membrane. Do not apply Bituthene membranes over lightweight insulating concrete.

^{*** For usage in China mainland, please follow China GB code requirement for lapping. For more details, please contact your local GCP representative.}
