Radon Mitigation Rough-in

Installing radon rough-in for commercial buildings is a requirement of the Alberta Building Code and also an important step towards ensuring the safety of the occupants of the building. Radon is a naturally occurring, odorless, and colorless gas that can be found in the air and can cause health issues if it builds up in a confined space.

Skyline has completed millions of square feet of radon rough-in throughout Western Canada. Installing radon rough-in involves sealing any cracks or gaps in the foundation of the building and running a radon collection pipe up through the building's structure. Our installers are experienced and can trouble-shoot issues that arise to provide a completely air-tight installation to pass CNRPP inspection criteria.

Our Radon services include:

Radon Rough-in Drawing Review:

We will review your building plans to ensure the radon rough-in will be useable as designed. We will look for common mistakes that may limit the usability of the rough-in for a future radon mitigation system. Following review, we will make recommendations to ensure the rough-in meets the Alberta Building Code and to improve its functionality.

Radon Rough-in Design:

The design will include selecting an appropriate location for the sub-slab and interior radon piping, considering house-finishing details. The design will provide detailed specifications for the porous sub-slab layer and polyethylene barrier installation. Recommendations for sealing wall/slab cold joints will also be provided to minimize the chance of failure as the slab pulls back. The radon rough-in design will be provided as a complete set of engineer-sealed drawings and specifications.

Radon Rough-in Installation:

Why not leave the radon rough-in installation to the professionals? We can install both the sub-slab and above-ground radon piping during building construction. We can seal the foundation wall/slab joints using approved sealants and methods. Sealing the slab properly will account for concrete shrinkage and minimize air leakage, thus reducing the chance of invasive work to access leaking joints in the future.

Radon Rough-in Inspection:

Regular inspections during the construction process can help ensure that a radon rough-in is installed properly. Mistakes are much easier to fix early in the construction process before the concrete slab is poured and drywall is installed. Skyline has CNRPP-certified inspectors who provide rough-in inspections for systems we have designed and also those designed by others. A full inspection report will be provided for your turnover documents.

Radon Mitigation:

In most cases, mitigating commercial buildings with high radon levels is a quick process, often completed in a week or less. We are always careful to protect your commercial building from damage and dust during mitigation work and will leave the work site clean and tidy. High radon levels can be reduced in most commercial buildings for about the same cost as other common home maintenance tasks, such as replacing a furnace or air conditioner.


Skyline is certified by the Canadian National Radon Proficiency Program (C-NRPP) for both radon mitigation and inspection.
