Pipe Penetration Leaks

When these particular pipes are put in place, contractors usually drill a hole through the wall and insert pipe sleeves to hold the conduit, sewer pipe or water line.  Most of the time water will leak from the back of the wall where the soil has eroded and then through the sleeve and out on to the floor.

Qualified contractors can use Alchemy-Spetec polyurethane water activated chemical grouts and oakum to repair these pipe penetration leaks.  (Oakum is a oil-free natural fiber that is used for filling voids.)

Here's how it's done:

  1. Soak the oakum in chemical grout, and then quickly submerge it in water. 
  2. Immediately pack the oakum around the pipe that is sitting in the sleeve.  It will harden in minutes and become a tightly sealed gasket. 
  3. If needed, use an injection needle to fill area behind the oakum with chemical grout.
