Gas Resistant Detailing Strip
A detailing strip suitable for sealing around penetrations within a membrane installation.
Application
Can be installed in both vertical and horizontal applications, above and below ground.
Description
Strip used for detailing work, when sealing a sheet membrane to penetrations e.g. steel columns, manholes and piles. It is manufactured using aluminium/polythene laminate coated on one surface, with an additional layer of self-adhesive polymer modified bitumen.
Features and benefits:
- Incorporates an aluminium foil core to provide resistance to the passage of methane, carbon dioxide and radon gases.
- Adhesion properties to primed surfaces.
- Multiple performance properties.
