Bituthene® 6000

Heavy duty, preformed composite membrane combining a self-adhesive rubber/bitumen compound and a tough, puncture-resistant 4 ply polyethylene waterproof laminate for waterproofing critical sub-structures and civil works

Product Description

Bituthene® 6000 is ideal for waterproofing structural concrete and civil works such as airports, rapid transit systems, power plants, environmental projects and earth sheltered structures and may be used in lieu of Bituthene 3000 on basements and substructures that require extra tough waterproofing protection.

Features

  • Waterproof — capable of resisting a hydrostatic head when fully supported.

  • Cross laminated — provides dimensional stability, high tear strength, puncture and impact resistance.

  • Single layer — simple, reliable, low labour cost with benefit of site programmed installation.

  • Cold applied — no heating, self-adhesive overlaps ensure continuity.

  • Chemically resistant — provides effective external protection against aggressive soils and ground water.

  • Flexible — accommodates minor settlement and shrinkage movement.

  • Controlled thickness — factory-made sheet ensures constant, non-variable site application.

  • Tanking security — combined flexible membrane and waterstop system for security.

Applications

Bituthene 6000 is a heavy duty, advanced, cold applied, flexible preformed waterproof membrane combining a special high performance 4 ply cross-laminated, HDPE carrier film with a self-adhesive rubber bitumen compound. The heavy duty advanced carrier film is manufactured by cross laminating and chemically bonding the layers together, to produce a film with greatly improved physical characteristics compared with traditional low density polyethylene films. Tear strength, puncture resistance and impact resistance are all increased to give a better factor of safety against accidental damage. When used in conjunction with Preprufe® membranes in reverse tanking applications and waterstops, cast into the concrete shell, it will provide a continuous waterproofing/ tanking system for sub-structures and civil works.

It is supplied to sites in rolls 1.6mm thick, 1m wide and 20m long (20 sq metres) and 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.

Applied to walls and to underground roof slabs, Bituthene 6000 will provide a continuous heavy duty moisture-waterproof barrier.

Being factory made, thickness of membrane is constant throughout and is not subjected to variations by site labour such as occur with brush applied materials. Bituthene 6000 is extremely flexible and well capable of bridging shrinkage cracks in the concrete and will accommodate minor differential movement throughout the service life of the structure.

Bituthene membranes should never be taken through load bearing brick/blockwork walls and must be linked with the damp-proof course to prevent extrusion under load.

Installation

Sloping or vertical faces shall be smooth, regular, dry and free from nails and primed with one coat of Primer WP-3000 applied by brush or roller, at a rate of 12 ~ 15 sq metre / litre depending on the porosity of the surface, and allowed to dry completely before the application of the Bituthene. Brickwork shall be flush pointed or rendered to provide a smooth surface before priming.

Where Bituthene is to be left temporarily exposed on vertical surfaces, batten fixing may be necessary to prevent slippage. Prior to backfilling remove battening and cover fully with a subsequent layer of Bituthene.

Bituthene 6000 shall be laid by peeling back the protective release paper and applying the adhesive face onto the prepared surface. The material 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 Bituthene Lap Roller to ensure complete adhesion and continuity between the layers. Damaged areas to be repaired by patching with an oversized patch applied to a clean dry surface and firmly rolled.

Following the application, care should be taken to prevent damage by following trades by using Servipak 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 Servipak or Korkpak spot bonded with Pak adhesive.Backfill material should be compacted in layers to prevent settlement and dragging forces being transferred to the waterproofing systems
