Do-It-Yourself Sub Slab Depressurization kit

Regular price $450.00 Sale

This kit contains all the difficult to find bits to complete your own Do-It-Yourself Active Slab Depressurization radon mitigation system.

These systems have demonstrated up to a 99% reduction in indoor radon levels. Just add Schedule 40 pipe, pipe cement and some sweat equity and you can start breathing safe again. Health Canada strongly recommends hiring a certified C-NRPP radon mitigation professional.  Professionals are able to properly determine airflow and fan sizing requirements, seal radon entry paths, identify potentially deadly back-drafting situations, and properly seal building envelope penetrations. 

However - if hiring a pro is not an option, following the DIY manual included in this kit gives you a good chance at constructing a radon mitigation system that is both safe and effective.  Be sure to consult with a pro if you have any questions relating to the safety of your system.
