Description: Performance over time is the only true test of a waterproofing system’s quality. Sika Sarnafil has been waterproofing green roofs and other landscaped areas across Europe for over 40 years and in the United States for over 30 years. When you specify a Sarnafil Green Roof, you get more than watertight security; you get peace of mind knowing you made the right choice. Sika Sarnafil’s Sarnafil G476 thermoplastic membrane is a key component in the Green Roof System. Sika Sarnafil has been using the same basic formulation in its manufacturing process for over 40 years. The Sarnafil G476 membrane is specially designed for sub-grade environments, compounded to remain watertight in extreme conditions including constant dampness, ponding water, high and low alkaline conditions, exposure to plant roots, fungi and bacterial organisms. The Sarnafil G476 thermoplastic membrane’s seams are also hot-air welded to provide a watertight, monolithic sheet. Sika Sarnafil has green roof systems for use on both concrete and metal deck applications. Sika Sarnafil’s Green Roof System can be installed three different ways; loose-laid, adhered or loose-laid with grid strips in order to provide the flexibility to choose the waterproofing application that best fits your buildings design criteria.
