    Description

    Stormwater catch basin had cracks and crevices allowing infiltration of soil and erosion of the surrounding ground. Originally buried underground, the 30″ incoming pipe had been uncovered from excessive soil erosion. This structure was posing a problem, especially due to its proximity to an airplane runway.

    Solution

    The Poly-Triplex Liner System was installed and cured with hydrostatic head pressure by building a framework around the openings so that they could be filled with water approximately 12 inches higher than the top of the structure. Monolithic liner was bonded to the walls of the catch basin.

    Benefit

    The liner has completely stopped the infiltration of soil and erosion of the ground around the structure.

    Left: Framework is being added to allow for hydrostatic head pressure for curing. Catch basin is prepared for the lining process.
    Upper Right: Bladder is being inserted into each of the three sections.
    Lower Right: Liner installation is complete and infiltration of surrounding soil is permanently stopped.

    Comments

    The Naval Air Station has used this Poly-Triplex System on numerous catch basin and manhole structures. Poly-Triplex has provided them a 10-year materials and labor warranty to stop infiltration and deterioration in these structures.
