Basement Waterproofing Photo Album: Radon Mitigation in Colonial Heritage Williamsburg, VA

Tyler Tetreault performed a radon test on this home during a recent real estate transaction. The readings came back higher than the EPA's action level of 4 pCi/L which recommends homeowners to take corrective measures to reduce radon entry and exposure. The new homeowners hired us to install a sub slab radon mitigation system which continuously runs and draws radon from underneath the basement slab and discharges it above the roof of the home. After the system was installed, Tyler Tetreault went back a performed a post mitigation test which revealed the radon levels below 1.0 pCi/L.

Radon Mitigation System - Back Corner of Home

Back corner of home where the outside portion of our radon mitigation system is located.

Radon Fan

Here is our radon fan which continuously runs and draws radon gas from underneath the basement slab. The coupling above the radon fan with the black hose attached is our fan moisture guard. Above the fan, condensation tends to build up in the pipe which can be detrimental to the fan. With the fan moisture guard in place, we're able to collect the condensation and drain it in order to prolong the life of the system.

Intake Pipe Penetrating to Outdoors

The radon intake (suction) pipe comes out of the basement through the rim & band joist. We then ran the intake pipe horizontally down the side of the house to the best location where we could connect to the radon fan and install the exhaust pipe to go up and above the roof.

Exhaust Pipe Above Roof

The exhaust pipe traverses the side of the home to the underside of the soffit. We then go around the soffit and 2' above the roof line to discharge the radon gas. At the very top of our exhaust pipe, we have a rodent guard in place to keep animals and debris from entering into our system.

Intake Pipe In Basement

A 4" hole is drilled through the basement slab in the desired location for the intake (suction) pipe. Our crew then removes (2) 5 gallon buckets worth of soil / rock through the 4" hole creating a cavity under the slab. This helps draw the radon gas to the intake pipe when the system is in place and running. The intake PVC pipe is installed through the slab hole and sealed in place.

U-tube Manometer and Labels

The U-tube manometer is a tool for our homeowners to be able to monitor the radon system's performance. The labels indicate the pipe is part of a radon mitigation system and has our contact information in the event the system needs servicing.
