SikaShield W159 ED 1.5 mm bitumen waterproofing membrane

A 1.5 mm bitumen waterproofing membrane that is stuck to concrete with the cement adhesive SikaShield W1 (wet application). It is reinforced with a cross-laminated PE film, stays flexible at -15 °C and has a removable liner on both faces. Use it for basements and other below-ground structures, vertical reinforced-concrete walls and single or strip foundations, as a single layer under heavy protection or as a base sheet in multi-layer systems. No torch is needed, so it is safe in confined spaces, and it can go on wet concrete. Not for roofs permanently exposed to UV.
