The present invention is method and resulting assembly for applying a flexible liner to the outer surface of a pre-cast concrete walled container to be buried in an earthen excavation.
Claims13
A process for forming a substantially waterproof barrier for at least the outer lateral sides of a pre-cast concrete container with a tank cavity adapted so that liquid is initially containable in at least 50 percent of an inside volume of the tank cavity, where the container is to be placed in an earthen excavation adapted to bury the container comprising:
- (a) a flexible, waterproof liner comprising polymer sheeting, flexible lateral sides adapted to sealingly enclose at least the lateral sides of the liner continuously from a bottom edge of the container to at least a top edge of the container, thereby forming a top opening in the liner with a top edge, the inside volume of the liner being larger than the volume defined by the outer sides of the container;
- (b) placing the liner in the excavation before placing the container therein;
- (c) placing the container in the excavation so that it is sealingly enclosed on at least the lateral sides by the liner;
- (d) sealingly placing a lid on the container;
- and
- (e) filling the remaining excavation space with non-bindable, porous material.
A process for forming a substantially waterproof barrier for at least the outer lateral sides and bottom of a pre-cast concrete container with a tank cavity adapted so that liquid is initially containable in at least 50 percent of an inside volume of the tank cavity, where the container is to be placed in an earthen excavation adapted to bury the container comprising:
- (a) a flexible, waterproof liner comprising polymer sheeting, flexible lateral sides extending from a liner bottom, the combination adapted to sealingly enclose at least the lateral sides and bottom of the liner, thereby forming a top opening in the liner with a top edge, the inside volume of the liner being larger than the volume defined by the outer sides of the container;
- (b) placing the liner in the excavation before placing the container therein;
- (c) placing the container in the excavation so that it is sealingly enclosed on at least the lateral sides and bottom by the liner;
- (d) sealingly placing a lid on the container;
- and
- (e) filling the remaining excavation space with non-bindable, porous material.
