Laminated containment structure
First Claim
1. A laminated containment structure, comprising:
- a plurality of adjacent, elongated laminated strips joined together along their opposite edge portions to form said containment structure;
each said laminated strip comprising a lamination of an elastomeric layer, and two geotextile fabric layers each bonded in face-to-face relation with a respective one of the opposite expansive surfaces of said elastomeric layer;
each said geotextile fabric layer of each said laminated strip being offset relative to a respective one of the opposite lateral edge portions of the respective elastomeric layer by a predetermined spacing to facilitate bonding of the elastomeric layers of adjacent ones of said laminated strips;
said elastomeric layer of each said laminated strip being continuously bonded in overlapping relationship directly to the elastomeric layer of each adjacent one of said laminated strips, with the overlapping portions of the elastomeric layers of adjacent ones of said strips generally corresponding in dimension to said predetermined spacing of each said geotextile fabric layers relative to its respective lateral edge portion of the respective elastomeric layer to form said containment structure with a substantially uninterrupted continuum of said elastomeric layers of said adjacent laminated strips and with substantially continuous expanses of said geotextile fabric layers on opposite expansive surfaces of said uninterrupted continuum of said elastomeric layers.

Abstract
A laminated containment structure, and method of making, are disclosed. In one form, the containment structure is configured as an expansive secondary containment liner particularly suited for use in association with bulk storage tanks for hydrocarbon fuels and the like. In an alternate embodiment, the structure is configured as a sealable container suited for storage and handling of harardous materials. The containment structure is configured for efficient manufacture and installation, as well as a high degree of resistance to puncture and leakage. Manufacture is facilitated by first forming a plurality of elongated laminated strips each comprising a lamination of a polyester elastomeric layer and at least one non-woven geotextile fabric layer. In the preferred form, a pair of the fabric layers are bonded to respective opposite expansive surfaces of each elastomeric layer, with the fabric layers offset from respective edge portions of the elastomeric layer to facilitate bonding of the elastomeric layers together to form the containment structure with a substantially uninterrupted expanse or continuum of the polyester elastomer.
