Bondall Bitumen Waterproofing Liquid is a premium, water-based bituminous coating designed to provide a seamless, flexible, and highly durable barrier against water penetration. Once cured, it forms a strong black membrane that adheres to concrete, brick, masonry, and metal surfaces, making it ideal for protecting structures from moisture ingress.

It is commonly used for planter boxes, retaining walls, underfloor slabs, concrete roofs, and general external waterproofing. The water-based formula is low in odor, easy to apply by brush, roller, or spray, and can be cleaned up with water before it dries.

The membrane offers excellent resistance to weathering, accommodates slight substrate movement without cracking, and delivers long-lasting waterproof protection in both above- and below-ground applications.
