Abstract
The present invention is method and resulting assembly for applying a flexible liner to a cementitious vault wall, wherein several forms are described for attachment of the liner to flowable and fully cured cementitious vault walls.
Claims14
A process for forming attachment of a flexible liner to a cementitious wall comprising:
- (a) the flexible liner comprising a sheet or sealed sections of sheets of a polymer material adapted to form a substantially continuous liquid tight seal against interior cementitious walls of a vault section;
- (b) a first mold piece having an outer surface generally conforming to the shape of the interior walls of the vault section;
- (c) a second mold piece having an inner surface generally conforming to the shape of outer walls of the vault section, thereafter effectively joining the first mold piece to the second mold piece such that a mold space is formed therebetween;
- (d) applying the liner to the outer surface of the first mold piece;
- and
- (e) supplying sufficient flowable cementitious material to the mold space whereby the liner forms an attached and substantially continuous liquid tight seal against interior cementitious walls of the vault section thereby formed.

An assembly of a flexible liner attached to a cementitious wall comprising:
- (a) the flexible liner comprising a sheet or sealed sections of sheets of a polymer material adapted to form a substantially continuous liquid tight seal against interior cementitious walls of a vault section, the liner further comprising a concrete side opposing the interior wall of the vault section, wherefrom such concrete side extend attachment means for improving attachment of the liner to the wall of the vault section;
- (b) the vault section having substantially attached to its entire interior walls the flexible liner;
- (c) sheets of the liner have been joined in a seam, excess of the seam material adapted to form attachment means which are held within the cementitious material;
- (d) the concrete side of the liner has embossments formed in the process of manufacturing the liner, whereby the interior walls comprise impressions of the embossments to which the embossments are attached;
- and
- (e) the concrete side of the liner has adhered to it a sheet of fibrous material, whereby cementitious material continuous with the interior walls of the vault section is intimately mixed with the fibrous material.

- (a) the flexible liner comprising a sheet or sealed sections of sheets of a polymer material adapted to form a substantially continuous liquid tight seal against exterior cementitious walls of a vault section;
- (b) a first mold piece having an outer surface generally conforming to the shape of interior walls of the vault section;
- (c) a second mold piece having an inner surface generally conforming to the shape of outer walls of the vault section, thereafter effectively joining the first mold piece to the second mold piece such that a mold space is formed therebetween;
- (d) applying the liner to the inner surface of the second mold piece;
- and
- (e) supplying sufficient flowable cementitious material to the mold space whereby the liner forms an attached and substantially continuous liquid tight seal against exterior cementitious walls of the vault section thereby formed.
