How radon enters
Radon Enters Through Openings Most Homeowners Cannot See
Radon is a naturally occurring radioactive gas that forms from uranium breakdown in soil and rock beneath your home. It enters through any available opening in the foundation — and because it has no colour, odour, or taste, testing is the only way to know what is present.
Foundation cracks
Slab joints & construction joints
Service pipe penetrations
Support post bases
Sump pits & floor drains
Exposed soil areas
RBM approach
A Building-Science Approach to Radon Mitigation
Entry Point Sealing & Preparation
RBM identifies and seals the primary radon entry points including foundation cracks, slab joints, service penetrations, and sump areas before system installation.
System Design & Installation
Each system is designed around the specific home — suction piping routed to the appropriate location, a high-efficiency radon fan selected, and clean exterior venting installed.
Post-Mitigation Verification
After installation, RBM conducts post-mitigation testing to confirm results. Most contractors skip this step. RBM does not.

Real mitigation result
From Elevated Radon Levels to a Verified Low Reading
In one recent mitigation project, Jeff was able to reduce radon levels from 514 Bq/m³ before mitigation to just 16 Bq/m³ after the system was installed and verified.
Results vary by building. RBM designs each mitigation system around the home’s foundation, pressure relationships, entry points, and test findings.
Before Mitigation
Radon levels measured 514 Bq/m³ before the mitigation strategy was completed.
Pre-mitigation reading example showing elevated radon conditions.
After Mitigation
Follow-up readings showed radon reduced to just 16 Bq/m³ after mitigation.
Post-mitigation reading example showing a low verified result.
What changed
Entry points were assessed and sealed where appropriate
A mitigation system was designed around the home’s conditions
Suction piping, fan placement, and venting were selected for performance
Follow-up testing was used to verify the result
