Cross Laminated Polyester Reinforced Self Adhesive Waterproofing Membrane


Bitustick R 3000 is a high performance self adhesive bituminous waterproofing membrane strengthened with a central core of heavy-duty, non woven polyester fabric with outstanding physical/mechanical characteristics and high puncture resistance laminated onto a top surfacing high density, cross laminated polyethylene film (for excellent dimensional stability and high tensile/tear resistance). The self adhesive side is a SBS modified bitumen compound which is protected with a silicon coated release film. A selvedge is provided on one side of the membrane to give a bitumen to bitumen contact on the overlaps.


  • Excellent puncture resistance and mechanical properties.
  • Cold applied self adhesive and easy to apply.
  • Excellent adhesion to vertical and horizontal surfaces. Improved heat resistance.
  • Excellent resistance to aggressive soil conditions, ground water / salts and contaminated water.
  • Excellent tear and tensile strength in both longitudinal and transverse directions.
  • Water and vapor proof.

Step by Step

Substrate preparation

As with any waterproofing membranes, proper application is of paramount importance to obtain optimum product performance. A smooth regular and dry surface is always a must for good application. The substrate should be completely free of any protrusions or cavities. The presence of oily materials, frost, dampness, moisture and any other contaminants should be completely removed.


Apply Polyprime SB solvented bituminous primer at the rate of 4 – 6 m²/L as a prime coat. The prime coat should be touch dry before the application of the membrane. The application temperature should be between 4°C to 45°C.


  1. Unroll only the required length, and cut the piece to the desired shape and size.
  2. Place the pieces of membrane on the area to be covered, and check whether they match with the profile of the marked substrate.
  3. Peel off release film and carefully place the membrane so as to ensure a minimum of 75mm overlap and then smoothen the membrane from the centre to the edges in order to drive out entrapped air.
  4. In case the concrete structure is at a greater depth or is going to be exposed to site conditions / weather for a long period, place Bituboard asphaltic protection board on top of the membrane soon after the application in order to prevent any damage to the membrane.


The membrane shall be protected from damage due to ongoing site activities or from aggregates during backfilling by a tough, weather, warp and rot proof asphaltic protection board (Bituboard /Bitustick R300/ Bitustick R400)*. Alternatively, on horizontal areas the membrane can also be protected by laying a cement sand screed (50mm). Bituboard can be fixed with a double sided adhesive bitumen tape (Watertite TS 15)*.


Bitustick R 3000 membranes are supplied in rolls of width 1m and lengths of 8m (3mm thick) and 10m (2mm thick) and are packed in loose corrugated boxes to avoid any damage during transit or at site. The membranes can be unloaded by hand or any other convenient means but ensure that there are no sharp or protruding edges within close proximity to avoid puncturing the membrane.
