Secondary containment system

A method for fabricating in place a secondary containment system for hazardous liquid escaping from a primary containment system, comprising:

• providing a support surface for bottom and side portions of the secondary containment system which support surface is below the primary containment system;
• providing a thermoset resin material which, prior to being set, is applied to the support surface as a fluid and thus shaped by the support surface and which, when it is set, forms a substantially rigid, durable, insoluble, liquid-tight, and chemical, corrosion and decomposition-resistant monolithic solid layer which forms a liquid-tight seal or bond with metallic, plastic or concrete material in contact therewith and which retains the shape in which it was applied;
• applying the provided thermoset resin material as a fluid to the provided support surface to form a monolithic layer of the shaped thermoset resin material on the support surface;
• and
• allowing the applied and shaped thermoset resin material to set to thereby form in place on the support surface the secondary containment system for hazardous liquid escaping from the primary containment system, which secondary containment system comprises the substantially rigid, durable, insoluble, liquid-tight, and chemical, corrosion, and decomposition-resistant monolithic solid layer which forms the liquid-tight seal or bond with metallic, plastic or concrete material in contact therewith.
