JUTA GP®1 SAM gas protection self-adhesive membrane is a bituminous gas-proof and waterproof sheet. It is used for the gas/ waterproofing of underground structures where harmful ground gases are anticipated and as a self-adhesive accessory to GP®1.
JUTA GP®1 SAM is composed of self-adhesive SBS polymer-modified bitumen incorporating GP®1 with an upper surface finish of Black reinforced LDPE, and a lower surface finish of siliconized release film.
Roll weights can be in excess of 20kg (approx. 33kg / roll) and hence appropriate care and equipment are required for unloading and handling. This product is non-toxic nor flammable.
Rolls of JUTA GP®1 SAM should be stored horizontally, and pallets should not be stacked on top of one another. It should be stored in a cool, dry place and be protected from exposure of rain, sun, heat and cold temperatures prior to installation. Exposure to sunlight for an extended period of time could cause difficulty with the removal of the release film.
