Abstract
A packaged membrane is adapted to be sold, stored and transported to the site of use. The membrane includes a base mat and a flexible cement-based coating applied to the base mat. The coating includes a hydraulic component and water. The membrane is then rolled and packaged in a tubular package. Preferably, the coating also includes a water-soluble, film forming polymer. It is also preferred that the hydraulic component include at least 50% fly ash by weight.
Claims17
A packaged membrane adapted to be sold, stored and transported to the site of use comprising:
- a tubular package;
- and
- a membrane, said membrane comprising a base mat and a flexible coating applied to said base mat, said coating comprising a hydrated hydraulic component, said membrane being rolled and packaged in said tubular package.
A packaged membrane comprising:
- a tubular package;
- and
- a coated membrane, said coated membrane comprising a base mat including at least three plies, a center ply of a meltblown polymer sandwiched between two plies of spunbond polymer, and a flexible coating applied to said base mat, said coating comprising a hydrated mixture of a hydraulic component and a water-soluble, film-forming polymer, and wherein said membrane is rolled and packaged in said tubular package.
