PVC sheet waterproofing membrane for below-ground and rooftop applications — 1.5mm thick, mechanically fastened or fully bonded.
Sikaplan WP 1100 is a reinforced PVC waterproofing membrane suitable for flat roofs, below-ground waterproofing, podium decks and water-retaining structures. Its fibre-reinforced core provides dimensional stability and puncture resistance.
The 1.5mm thickness provides robust protection in exposed applications. Welded laps using hot-air or solvent welding create a monolithic, watertight barrier. Available in a range of colours for rooftop installations.
Applicable to concrete, masonry, steel and timber substrates. Supplied in 2.05m × 5m rolls (approximately 10m² per roll). Backed by a Sika system warranty when installed by a Sika-trained applicator.
