Abstract
A method is provided for preventing water from entering a containment sump of an underground storage tank. After accessing an interior of the sump and interrupting the flow paths of piping, a form is positioned in the sump. An annular open space formed between the sump's sidewall and the form is substantially filled with a settable material. An inside wall of the form next has applied to it a polymeric material to seal off an source of water seepage. The piping flow paths are reestablished to create a waterproof containment sump.

A method of preventing water from entering an interior area of a containment sump associated with an underground storage tank comprising the steps of:
- (a) accessing the interior area of the containment sump;
- (b) positioning a rigid form into the sump's interior area, said form extending from a base of the containment sump to at or near a top of the containment sump, whereby the interior area is divided into an outer annular open space and a reduced interior area;
- (c) introducing a settable mixture into the outer annular open space to substantially fill it;
- (d) sealing any piping to the form where the piping enters through the form;
- and
- (e) applying a polymeric material to an interior wall of the form to substantially cover the surface of the form's interior wall,
- whereby water is blocked from entering the reduced interior area of the containment sump by the settable mixture and by the polymeric material.
A method of preventing water from entering an interior area of a containment sump associated with an underground storage tank comprising the steps of:
- (a) accessing the interior area of the containment sump;
- (b) interrupting the flow path of any piping which extends through the containment sump's sidewalls into the interior area of the containment sump;
- (c) positioning a rigid generally cylindrical-shaped form into the sump's interior area, said form extending from a base of the containment sump to at or near a top of the containment sump, whereby the interior area is divided into an outer annular open space and a reduced interior area;
- (d) introducing a settable mixture into the outer annular open space to substantially fill it;
- (e) reestablishing the flow path of the piping within the containment sump's inner open space;
- (f) sealing any piping to the form where the piping enters through the form;
- (g) applying a polymeric material to an interior wall of the form to substantially cover the surface of the form's interior wall;
- and
- (h) installing a light admitting lid onto the containment sump, whereby water is blocked from entering the reduced interior area of the containment sump by the settable mixture and by the polymeric material.
