Duram Bituflex | Rubberised Bituminous Waterproofing

Duram Bituflex Rubberised Waterproofing Membrane

Duram Bituflex is a high-performance, water-based rubberised latex and bituminous waterproofing compound. Engineered with advanced elastomers and reinforcing agents, it provides a brushable, high-build membrane that is both user-friendly and non-hazardous. Unlike traditional bitumen products, Bituflex will not stain grout or tiles and remains stable without re-emulsifying after a full cure.

Primary Uses

  • Non-timber wet areas (bathrooms, laundries)
  • Retaining walls and landscape structures
  • Decks, patios, and balconies (covered or tiled)
  • Terraces and general-purpose non-exposed applications

Features & Benefits

  • Cost-Effective: Designed as a highly economical solution for short to medium-term waterproofing.
  • Non-Hazardous: Water-based formula is safe for installers and the environment.
  • Versatile Application: Can be applied to damp substrates (surface water must be removed).
  • Durability: Formulated to provide a thick, protective barrier that resists moisture ingress.

Suitable Surfaces

Bituflex is compatible with most common construction substrates, including concrete, cement render, FC sheeting, compressed sheeting, plasterboard, block work, and brick. Note: While it can be applied to damp surfaces, the drying time will increase, and constant dampness will prevent curing.
