Product type
Bitumen waterproof membranes are durable, flexible sheets made from bitumen, a byproduct of petroleum, often reinforced with materials like fiberglass or polyester. These membranes are designed to provide a waterproof barrier for various construction applications, preventing water infiltration and protecting structures from moisture damage. They are commonly used in roofing, foundation waterproofing, and below-grade applications.
