Drain Tile Depressurization
Waterproofing systems in homes (i.e., channel drains) can serve as pathways for radon. When we are performing diagnostics, if radon levels are shown to be in the channel drain, we will core a 5-inch hole through the slab in a location around it. The radon vent pipe will then be insterted where it will touch the corrugated pipe below the slab. This allows the air below the slab in the channel drain to be pulled into the mitigation system.
To prevent air loss, we can also seal the channel drain. However, if the basement has problems with water intrustion, this is generally not recommended, but, due to the loss of pressure, we cannot gaurantee the effectiveness of the mitigation system. If this applies to your home, one of our experienced radon professionals can, during the initial inspection, help you understand all of your options and help you determine the best solution for your home.
