Radon Remediation

Sub-Slab Depressurization

Sub-slab venting is an effective means of reducing radon levels.


The following photos show typical examples of radon mitigation in Elliot Lake, Ontario using an in-line fan to produce active sub-slab depressurization with successful results.
The post-mitigation radon levels are all below 100 Bq/
m3 and well below the guideline of 200 Bq/m3.
