Bitulen SK374 Self-Adhesive Bituminous Membrane ® Bitulen SK374 is a self-adhesive 1.5 mm thick preformed waterproofing membrane for use in basements and substructures, to protect against water ingress. ® Bitulen SK374 comprises of cross-laminated SBS modified bitumen. The underside is protected by a silicone coated release paper. ® Bitulen SK374 meets the requirements of Singapore Standard SS 374:1994 for preformed sheet membranes. ® Bitulen SK374 provides an effective waterproofing membrane for foundations, tunnels, floors and flat roofs. Being cold-applied, it is ideal for installation in restricted and confined spaces. Areas of Application • Basement walls & slabs • Tunnels • Concrete structures Advantages • Easily applied • Self-adhesive • Resistant to hydro
