Weston, CT Sub slab sump suction | Waterproofing by CT Radon & Well Water Solutions

Active Soil Depressurization (ASD) or Sub Slab Depressurization (SSD) can also workin concert with a waterproofing system. Sump suction, or sub slab sump suction can be very effective in lowering airborne radon concentrations provided that the water level under the slab isn't above the lateral pipe network under the slab.

An interior footing drain system consists of perforaed pipe in a bed of gravel that runs along the footing inside the basement footprint. It typically dumps into a sump basin where the sump pump is located. This perforated pipe and gravel channel can help move a lot of air out from under the slab when we tap our suction point near it. Tapping into the actual sump is not necessary.
