Abstract
The method of the present invention results in a secondary containment area for above ground storage tanks. The method involves leveling the site, laying a foundation bed, building a retaining barrier around the site, covering the foundation bed and retaining barrier with a liner cloth, and applying a layer of polyurea to the liner cloth and retaining barrier.
Claims18
A method for constructing a secondary containment area for above ground storage units of varying size, shape and orientation relative to the ground, comprising the steps of:
- (a) providing a site for a storage unit;
- (b) building a retaining barrier around said site;
- (c) covering said site and a portion of the retaining barrier with a geotextile;
- and
- (d) coating said geotextile with at least one coat of polyurea to form a polyurea coating thickness of at least 30 mils to about 59 mils,
- wherein said method result is in the formation of a solid, impermeable layer throughout the geotextile and polyurea coating.
A method for applying a polyurea coating for the construction of a secondary containment area, said method comprising the steps of:
- (a) building a retaining barrier having inner and outer walls around a containment area;
- (b) covering said containment area and a portion of the retaining barrier with a geotextile;
- (c) applying a light base layer of polyurea to the geotextile;
- (d) applying at least two more layers of polyurea to the geotextile and retaining barrier to form a polyurea layer comprising a thickness of at least 30 mils to about 59 mils,
- wherein said method result is in the formation of a solid, impermeable layer throughout the geotextile and polyurea layers.
