Radon is a radioactive, colourless, odorless and tasteless noble gas, occurring naturally as the decay product of uranium in the soil. When it decays it will travel through the dirt and seek any openings in the lower levels of homes. There can be many openings in the basement of homes including floor and wall cracks, open sump pits, damaged floor drains or brittle mortar between blocks.

 

Repairing the openings is just one step to mitigate radon gas that is entering the basement. Once the area is sealed properly, Radon Gas venting should be added to protect the occupants. Advanced Basement Systems was called to do a complete mitigation system in this home. Fixing all the cracks then adding the vent system will reduce the Radon Gas Levels making the home safe to live in.

 

If you are worried about living with Radon Gas, call Advanced Basement Systems to protect yourself and your family.

Problem: This century-old home had the challenge of mixed foundation types as well as varying levels. The basement leaked even during moderate rainfall which caused excess humidity and all the problems associated with an excessively humid environment.

Solution: With our interior waterproofing process, we were able to successfully and permanently fix this leaky basement. We waterproofed the leaking walls, improved the drainage in the space and also installed a sump pump more than capable of helping to keep the basement dry.

Job Stories From St Thomas, ON
Radon Gas Solution in St Thomas, ON

Radon Gas will seek any opening in a basement to enter the home. The air pressure in a basement is usually lower than the outside as air will migrate to the upper levels of the home during the heating season.

 

Cracks in the floor and walls are one of the main culprits to let radon gas into the home. Advanced Basement Systems wall called to a home in St Thomas, ON after the home owner found high levels with proper testing. Large cracks under the carpet were discovered during the inspection. The mitigation included repairs to the cracks and a proper powered vent system installed.

 

The home is now testing lower levels of Radon gas and is safe for the home owners.
