Gripset Betta Bitumen Rubber Waterproofing Membrane 15L

Vendor Builders Mitre 10

Seal, protect, and waterproof with a versatile, solvent-free liquid membrane designed for demanding residential and trade applications. This brush-on solution forms a tough, seamless waterproof coating with excellent flexibility and adhesion, making it ideal for retaining walls, cellar and basement walls, water-bearing structures, and general building surfaces. User-friendly and environmentally safe, it is easy to apply, wash, and clean, without impacting delicate aquatic conditions.

Suitable only for porous substrates, it adheres to concrete, masonry, brick, timber, cement sheeting, metals, and aged bitumen. Apply in thin or thick beds, even onto damp surfaces (free of surface water). It doubles as a waterproof adhesive for lightweight materials and offers valuable sound-deadening, rust prevention, and timber rot protection.

As a smart 2-in-1 solution, it can be used as a high-performance Bitumen Polymer Membrane or diluted 1:1 with water to create a cost-effective Bitumen Paint for areas where a full membrane isn’t required—delivering outstanding value for both trade and general applications. Approved for potable water exposure (1000mm²/l), it’s also suitable for ponds and other water-bearing objects when applied to compatible surfaces.
