Preformed Bituminous Self Adhesive Waterproofing membrane


Bitustick 1000 is a 1mm thick preformed self adhesive modified bituminous membrane specifically designed for waterproofing and damp proofing of below ground concrete structures where the ground water table is low. Bitustick 1000 conforms to the requirements of BS 8102.


  • Preformed thickness. Ensures application of a minimum and uniform thick membrane
  • Easy and fast application. Same day screeding or backfilling
  • Seamless adhesion on overlaps
  • Resistant to chlorides, sulphates, dilute alkalis and acids
  • Good crack bridging ability
  • Good tear and puncture resistance
  • Good resistance to hydrostatic pressure
  • Effective sealing of pin holes & blow holes

Step by Step

Substrate preparation

The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. All surface imperfections, protrusions, structurally unsound and friable concrete must be removed and repaired.


Apply Polyprime SB* (Solvent based primer) @4-6 m²/L to a clean, smooth and dry surface by brush, roller or spray. Allow the primer to dry prior to the application of the membrane. The primer promotes the adhesion between the membrane and the concrete surface.


Start the installation of all membrane plies from the low point or drains, so that the flow of water is over or parallel to the plies, but never against the laps. All overlaps at the membrane seams shall be installed so as to have "up" slope laps over "down" slope laps. Begin membrane application by unrolling the roll of Bitustick 1000 membrane and aligning the side laps. Re-roll the roll halfway and stand on the unrolled portion to prevent shifting. 


Peel off the release film from the self adhesive side and start unrolling the membrane and press it to the surface. Smoothen out the membrane from the center to the edges in order to drive out entrapped air with a wooden press. Furthermore, an iron roller shall be used for rolling on top of the applied membrane to ensure a proper and strong adhesion of the bitumen compound with base surface. Side overlaps shall be a minimum of 50mm on the selvedge and end overlaps 100mm


Though the membrane has good impact, puncture and abrasion resistance, for areas where there are high concentration of coarse and sharp backfill aggregates, it is highly recommended to protect the membrane with a tough, weather, warp and rot proof asphaltic protection board (Bituboard*). Bituboard can be fixed with a double sided adhesive bitumen tape (Watertite TS 15). Alternatively a 1000 gauge polyethylene sheet can be used for protecting the membrane.
