4. 4 4/5 Sikaplan ® WP 1100 - 20HL Notes on Application / Limitations Installation works shall only be carried out by Sik a ® trained contractors, experienced in the lining of tunnels and undergroun d structures. The membrane is not resistant to permanent contact with materials including bitumen, and plastics other than PVC; on these it r equires a separation layer of geotextile (> 300 g/m 2 ). Sikaplan ® WP 1100 – 20HL is not suitable as sheet waterproofing membrane fo r tunnels, when exposed to permanent water temperatur e exceeding + 30°C and when exposed to polluted, or waste waters. It can b e exposed temporary to ground water or polluted water with temperature up to 50°C for 3 months. The water tightness of the structure must be approv ed after completion of the membrane installation works according to the requir ements of the client’s specifications. The membrane is not UV stabilised and must not be i nstalled on structures where it is permanently exposed to UV light and weathering. It can be exposed temporary to UV light up to 6 months.

Shotcrete: The profile of the shotcrete surface must not excee d a ratio of length to depth of 5:1 and its min. radius must be 20 cm. The shotcrete surface must not contain broken aggre gates. Any leaks shall be sealed with Sika ® waterproof plugging mortars, or drained with Sika ® FlexoDrain. Where necessary to achieve the desired profile/surf ace, apply a fine sprayed concrete layer on the shotcrete surface with a min. thickness of 5 cm and aggregate diameter not exceeding 4 mm. Steel (girders, reinforcement mesh, anchors, etc.) must also be covered with a minimum 5 cm of fine sprayed concrete. The surface of the shotcrete and fine sprayed concr ete must be cleaned (no loose stones, nails, wires, etc.). Substrate Temperature 0°C min. / +35°C max. Ambient Temperature +5°C min. / +35°C max. For installation below +5°C ambient temperature, sp ecial measures for safety requirements may be required in accordance with rel evant national regulations. Ambient Temperature of Liquids +30°C maximum Application Method / Tools Installation method: Loose laid and mechanically fastened, or loose laid and ballasted in accordance with the separate Sika ® Method Statement and Application Manual for sheet waterproofing membrane installations. All membrane overlaps must be heat welded i.e. usin g hand welding guns 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-auto matic: Leister Triac Drive). Use Sika-Trocal ® Cleaner 2000 for seam preparation and cleaning of slightly soiled membrane surface. Welding parameters, such as speed and temperature m ust be established with trials on site, prior to any welding works.
