Abstract
A lining system for lining a surface generates a fluid impervious lining and an interstitial space between said lining and said surface. The system includes a layer comprising a flexible material having an adhesive coating on each side thereof, a second layer of flexible material, and a spacing means to generate a gap between the first and second layers, the gap constituting the interstitial space, and a coating, the coating comprising a curable material which cures to form a hard fluid impervious coating.
Claims16
A fluid impervious composite material comprising:
- (i) a first layer of flexible sheet material;
- (ii) a spacer layer attached to the first layer of flexible sheet material;
- and
- (iii) a second layer of flexible sheet material comprised of a flexible fluid impervious foil sheet situated between a fluid impervious curable coating and the spacer layer;
- wherein:
- the spacer layer provides an interstitial space between the first and second layers of flexible sheet material;
- a reinforcement layer is located to the side of the flexible fluid impervious foil sheet material distal from the spacer;
- the layers of the composite material have surfaces and are attached one to the other surface to surface by adhesive between adjacent layers;
- and
- the fluid impervious curable coating attached to the reinforcement layer, wherein the fluid impervious coating is not flowable in liquid form when cured.
A tank having a lining of a fluid impervious composite material comprising:
- a tank having an inner surface;
- and
- a lining of a fluid impervious composite material attached to the inner surface of the tank, the lining of a fluid impervious composite material including:
- (i) a first layer of flexible sheet material having on at least one side thereof;
- (ii) a spacer layer attached to the first layer of flexible sheet material;
- and
- (iii) a second layer of flexible sheet material comprised of a flexible fluid impervious foil sheet situated between a fluid impervious curable coating and the spacer layer;
- wherein:
- the spacer layer provides an interstitial space between the first and second layers of flexible sheet material;
- a reinforcement layer is located to the side of the flexible fluid impervious foil sheet material distal from the spacer;
- the layers of the composite material have surfaces and are attached one to the other surface to surface by adhesive between adjacent layers;
- the surface of the first layer of flexible sheet material is attached to the inner surface of the tank by adhesive therebetween;
- and
- the fluid impervious cured coating is attached to the reinforcement layer, wherein the fluid impervious cured coating is not flowable in liquid form when cured.
