Leaking Outfall Pipe

Challenge:

Leaking Outfall Pipe

Solution:

Non-excavating, multi-solution involving stabilization of settling soil and elimination of visible water back-flow. Water level lowered to facilitate access. Strategic placement of injection tubes above pipe to avoid contact with pipe or liner in place. Stabilized soil behind wall, filled voids. Drilled down through soil above the leak to force polymer towards the pond around the local area of pond. Polymer was injected directly into concrete wall above pipe in two areas until we saw outcropping.

Results:

Leak was sealed, and surrounding soils, rocks and structure stabilized
