BBA Agrément Certificate
Certificate type
Robust Type A, pre-applied, fully bonded, gas-resistant waterproofing membrane for use in below ground, reinforced concrete structures.
Application
- Formwork, oversite concrete or compacted sand blinding on granular fill.
- Both the horizontal and the vertical using one grade of membrane.
- For concrete basements, lift pits, carparks and other water excluding structures.
- Provides water, water vapour and gas protection to water excluding structures and protects concrete from aggressive ground salts, chemicals and hydrocarbons.
Description
A waterproofing membrane, which mechanically bonds to poured cast in situ concrete, remaining in place if settlement of the substrate occurs. A polyethylene membrane faced with a bonded complex cell mesh, allowing poured concrete to interlock with the membrane.
Features and benefits:
- Unique mesh system bonds permanently to concrete, remaining in place even if settlement takes place
- Smart anti-tracking design prevents water tracking between membrane and concrete
- Simple and quick to install - no protection film to remove
- Provides Methane and Carbon Dioxide protection as defined in BRE Report 212 and independent assessment report
- Crack bridging up to 5mm (100 cycles) ASTM C1305 modified
- Radon protection as defined in BRE Report 211
- BBA certification
- Protects concrete from attack from chemicals, hydro- carbons and aggressive ground salts in contaminated sites
- Simple application - requires no primer or protection, and blinding concrete may be eliminated
- Inert product - no risk of a reaction with ponded water prior to concrete being poured
- Membrane composition gives excellent flexibility for detailing, combined with high durability and toughness for site trafficking.
- Root resistant
- Long life expectancy.
