SUBSTRATE QUALITY

In-situ concrete: Steel-trowel finished, clean, sound and free of standing/running water, homogeneous, free from oils and grease, dust and loose or friable particles.
Shotcrete: The profile of the shotcrete surface must not exceed a ratio of length to depth of 5 : 1 and its minimum radius must be 20 centimetre. 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 minimum thickness of 3 to 5 centimetre and aggregate diameter not exceeding 8 millimetre. Steel (girders, reinforcement mesh, anchors, etc.) must also be covered with a minimum of 4 centimetre fine sprayed concrete. The shotcrete surface must be clean (no loose stones, nails, wires, etc.).
A polypropylene geotextile (≥ 350 g/m2) or a compatible drainage layer must be installed prior to the Sikaplan® WP 1100-20 HL membrane installation. For detailed information regarding system structure please refer to the method statement.
