Unlike plastic or bitumen-based alternatives that degrade under sustained root pressure and soil moisture, our rubber waterproof sheet maintains its full structural integrity for over 25 years in both exposed and buried conditions, making it the most dependable foundation for any green roof, landscape installation, or planted terrace project. The waterproofing sheet for roof membrane is completely non-toxic and environmentally safe, containing no harmful plasticizers or chemical additives that could leach into drainage water or harm surrounding plant life and soil ecosystems. These rubber sheets for roof applications are lightweight, weighing just around 1.25 kg per square meter, which reduces the structural load burden on existing roof decks significantly. CE certified and internationally compliant, this flat roof waterproof membrane from Polygomma is the eco-conscious, performance-driven solution for every sustainable roofing and landscaping project.
