SikaProof®-110 PP-700

FULLY BONDED, PRE-APPLIED WATERPROOFING MEMBRANE FOR TUNNELS WITH A 700 G/M2 GEOTEXTILE LINEARLY FIXED AT THE BACK

SikaProof®-110 PP-700 consists of a flexible polyolefin (FPO) layer membrane (EVA based) with a hybrid bonding layer that forms a mechanical and chemical dual bond with the in situ concrete lining, and a non-woven polypropylene geotextile (felt), which is linearly fixed onto the membrane during the manufacturing process and serves as a protection.

  • Strong mechanical and chemical bonding properties on inner concrete lining
  • No lateral water migration between inner concrete structure and membrane
  • Excellent thermal jointing properties
  • Highly flexible, also in cold temperatures
  • Strong crack bridging ability
  • Fast and simple installation

Application

Application steps

SUBSTRATE QUALITY

The profile of the shotcrete surface must not exceed a ratio of length to depth of 5:1 and its min. radius must be 20 cm. The shotcrete surface must not contain broken aggregates. Any leaks must be sealed with Sika® waterproof plugging mortar, or drained with a Sika® FlexoDrain system. Where necessary to achieve the desired profile/surface, apply a fine sprayed concrete layer on the shotcrete surface with a min. thickness of 3-5 cm and aggregate diameter not exceeding 8 mm.

Steel (girders, reinforcement mesh, anchors, etc.) must also be covered with a minimum of 4 cm fine sprayed concrete. The shotcrete surface must be clean (no loose stones, nails, wires, etc.).

APPLICATION

The SikaProof®-110 PP-700 membrane is installed loose laid and mechanically fastened in accordance with the Sika Method Statement for sheet waterproofing membrane installations (available separately on request).

The jointing faces must be dry and free from contaminations. For contaminated / soiled surfaces, follow the instructions for cleaning and preparation etc. in the Sika Method Statement.

All membrane overlaps must be thermally jointed using hand welding gun and pressure rollers or automatic heat welding machines, with individually adjustable and electronically controlled welding temperatures (such as the manual Leister Triac PID / automatic: Leister Twinny S / semi-automatic: Leister Triac Drive). Thermal jointing parameters, such as speed and temperature must be established with trials on site, prior to any thermal jointing works.

T-joints demand specific preparation of the thermal jointing area. For more specific instructions refer to the Sika Method Statement.
