Rubberised Bitumen Emulsion
Cold-Applied Damp-Proof & Below-Ground Waterproofing Coating
- Solvent free, non-flammable and non-toxic
- Single component, no mixing required
Product Overview
Rubberised Bitumen Emulsion is a single-component, cold-applied, thixotropic bitumen-latex waterproofing coating designed for damp-proofing and waterproofing below-ground structures. Supplied as a dark brown, solvent-free liquid, it dries to form a flexible, resilient and impervious membrane.
By combining the waterproofing properties of bitumen with the elongation and crack-bridging performance of rubber latex, this emulsion provides durable protection against moisture ingress while accommodating minor substrate movement. It is non-flammable, non-toxic and resistant to chloride and sulphate attack, making it suitable for long-term concrete protection.
Rubberised Bitumen Emulsion also functions as an effective vapour barrier and curing compound, allowing curing and waterproofing to be achieved in a single application.

Recommended Uses
- Damp-proof membrane behind retaining walls
- Basement and foundation waterproofing
- Tanking of below-ground structures
- Sandwich membranes in new floor construction
- Vapour barrier under screeds
- Curing compound for concrete
- Waterproofing for floors, walls and roofs (non-exposed)
Advantages
- Single-component, cold-applied system
- Solvent-free, non-flammable and non-toxic
- Flexible membrane with excellent crack-bridging ability
- Strong resistance to moisture, chlorides and sulphates
- Acts as both waterproofing membrane and vapour sealer
- Suitable for green and cured concrete
- Thixotropic consistency prevents sagging on vertical surfaces
- Can be applied by brush, roller or squeegee
- Also suitable as an adhesive for insulation and flooring materials
Advantages
Surface Preparation
- Surfaces must be clean, sound and free from dust, dirt, oil, rust or loose material.
- Porous substrates such as concrete and fibre-cement should be primed using the emulsion diluted 1:4 with clean water.
- Old concrete must be structurally sound. Steel surfaces should be mechanically cleaned and treated as required.
Foundation & Below-Ground Protection
- Can be applied directly to green concrete once formwork is removed
- Apply two coats at right angles to ensure full coverage
- Clean sharp sand may be broadcast into the wet coating to increase dry film thickness (DFT)
Sandwich Membrane (New Floors)
- Apply two coats to smooth, clean concrete at approx. 1 m² per litre per coat
- While the second coat is tacky, blind with clean sharp sand
- Extend membrane up walls to meet the damp-proof course
- Apply screed (minimum 50 mm thickness) once membrane has dried
Existing Floor Treatment
- Apply primer coat diluted 1:4 with water at approx. 7.5 m² per litre
- Once dry, apply two full coats at approx. 1 m² per litre per coat
- Ensure membrane is not damaged prior to installing floor finishes
⚠️ Floor coverings containing high levels of solvents or plasticisers should not be applied over this membrane.
⚠️ Will deteriorate under UV, protect with water-based paint or cover with protection board in exposed areas
Coverage
Coverage varies depending on surface porosity and texture.
- Typical coverage: 2–3 m² per litre (two coats)
- Minimum recommended coverage: 2–4 m² per litre
Limitations
- Not UV resistant – must be protected if exposed
- Can be over-coated with suitable water-based paints
- Not suitable for negative hydrostatic pressure applications
- Not intended for permanently exposed external conditions
