Ground Water Penetration
Any Pipe that vents outside a foundation wall below grade height is susceptible to allowing ground water to penetrate the interior of a home. Such pipes may be; sump pump vents, furnace exhausts, oil tank connections, gas lines, dryer vents and any thing that exists the building through the foundation wall. Leaks generally occur directly around the service pipe entrance or exit.
Signs of a Service Pipe Leak
A few signs that a leak has occurred or continues to are;
1) Efflorescence, which is left over lime, calcium or other minerals after the moisture that penetrated has evaporated.
2) Sign of dirt that has come in with water that leaves staining on the wall or even build on the floor.
3) Signs of rust on the foundation wall coming directly from the service pipe area caused by the corrosion of metal venting pipes.
The Most Effective Method
In order to repair leaky foundation service pipes and vents without exterior digging. The most effective and often method used is through the injection method either with epoxy or polyurethane.
How the Method is Carried Out
Very similar to the crack injection method, an injection port or ports are adhered to the foundation wall over an opening directly around the pipe. In some cases holes may need to be drilled in the concrete to allow for penetration of the product to be injected. An epoxy surface seal paste is applied around the service pipe and any other leaking area making the injection ports the only way in or out of the leaking area. After the surface seal material is fully cured the leaky area is injected and the process is complete.
The use of Hydraulic Cement
Only in the case that the leaking area is actively leaking at the time of repair epoxy will be replaced by Hydraulic Cement. Hydraulic Cement is very effective when used in the repair of actively leaking areas as it cures through a chemical process that will take place and the product will cure even under water. However Epoxy is the most often used product due to its significant bonding and structural strength.
Crack injections are the best and most effective way to waterproof and fix dry and or currently leaking cracked foundation walls, without costly exterior diging.
