Bituminous membrane is produced by modifying bitumen with polymer additives (APP and/or SBS). This modification increases the product’s resistance to both high and low temperatures, providing ease of application in hot and cold environments. The modified bitumen is impregnated into suitable fiberglass and polyester mats and laminated in various forms to suit different applications (Polyethylene Film – Aluminum Foil – Mineral Stone).
Bituminous membranes are reinforced with polyester materials. These types of membranes offer high performance and provide long-lasting durability. Due to the rubber content, they have a much more flexible structure, making them well-prepared for situations that may lead to shrinkage.
Bitumen-based waterproofing membranes provide protection against water for concrete surfaces buried underground, retaining walls, terraces, concrete roofs, wet floors, and highway viaducts. In membrane application, they are applied using a blowtorch, hot air gun, or hot asphalt bonding technique.
