RadonX pipe is a specialized PVC piping system used to collect and vent naturally occurring, hazardous soil gases, primarily radon, from beneath a building's foundation to the outdoors, preventing dangerous buildup inside homes and reducing lung cancer risk. It's a complete, engineered solution from IPEX that includes pipes, fittings, and cement, designed for new low-rise construction and retrofits to create a sub-slab depressurization system. 

Available in perforated and solid pipe. You can also find all fittings, cement, and accessories to complete your job up to the Ontario Building Code.

Key Functions

Soil Gas Collection: Perforated RadonX pipe is laid in the sub-slab area to capture radon and other soil gases.

Venting: The collected gas is channeled through a vent stack (often using solid RadonX pipe) to the outside, away from the living space.

System Integrity: RadonX is a unique system that performs best independently. Meaning components shouldn’t be mixed with other manufacturers’ products to ensure a leak-proof seal against radon.

Why Radon Mitigation is Important

Health Impact of Radon: Radon is an odorless, colourless, radioactive gas. It is naturally produced during the decay of uranium, and is present in all soil and rock types. The decaying process emits alpha particle radiation which severely damages DNA. It is classified as a Category 1 Class A Carcinogen. Radon is the second leading cause of lung cancer after smoking, accounting for 16% of lung cancer diagnosis.

Soil Gas Venting: Over time, radon can seep into a home through cracks and openings in the foundation. If not adequately vented, it can build to concentrations that pose a serious health hazard. The RadonX Soil Gas Venting System from IPEX is Canada’s first PVC radon gas piping system. Consistoing of perforated gas collector and venting pipes, fittings, accessories and solvent cements. Working together as an engineered system, RadonX safely collects and vents soil gas before it enters your home.

Code Compliance: RadonX pipe is engineered to meet specific building codes and standards for radon mitigation. Creating a pathway for harmful soil gas to escape harmlessly before it can enter your home.

Understanding the Ontario Building Codes and Standards Compliance for Radon Venting

There is presently no dedicated piping standard for the application of soil gas venting. However, RadonX is tested to and complies with the recognized standards outlined below.

The physical dimensions and tolerances of our radon venting pipe and fittings comply with CSA B181.2 and Section 9.13.4.3. Material Standards of the Ontario Building Code. RadonX vent pipe and fittings are approved for non-combustible construction, when tested to the CAN/ULC S102.2. Achieving a Flame Spread Rating of not greater than 25.

Interpreting These Building Codes

CSA B181.2 refers to the Canadian Standards Association (CSA) standard for PVC and CPVC Drain, Waste, and Vent (DWV) Pipe, Pipe Fittings, and Accessories. This standard covers poly(vinyl chloride) drain, waste, and vent (PVC-DWV) pipe, pipe fittings, and accessories such as factory-assembled expansion pints, closet flanges, and backwater valves.

This standard includes requirements for materials, workmanship, dimensions and tolerances, impact strength, chemical resistance, water resistance, dimensional stability, hydrostatic strength, solvent cement, and marking, as well as performance requirements for expansion joints, closet flanges, and backwater valves.

Our Interpretation of CSA B181.2:  RadonX pipe and fittings meet or exceed the strength and resistance requirements for safe use in home construction as per the Canadian Standards Association (CSA).

Section 9.13.4.3. Material Standards of the Ontario Building Code states that materials used to provide a barrier to soil gas ingress through floors-on-ground shall conform to CAN/cgsb-51.34-M, "Vapour Barrier, Polyethylene Sheet, for use in building construction". CAN/cgsb-51.34-M is a classification system and specifies physical property requirements. This document covers a material intended to be used in building construction applications, that may be used above grade or in contact with the ground. These values are intended for use in specifications, product evaluations and quality control. They are not intended to predict in situ end-use product performance. 

Our Interpretation of Section 9.13.4.3:  RadonX pipe and fittings meet or exceed the physical property and quality control requirements for building construction as per the National Standard of Canada.

CAN/ULC-S102.2 is the standard method of test for surface burning characteristics of flooring, floor coverings, and miscellaneous materials and assemblies. Set by the National Standard of Canada. This Standard is applicable to:

• The finished surface or covering of a floor extending to a maximum depth of 65 mm.
• Materials which cannot be tested as described in Clause 1.1 of CAN/ULC-S102, Standard Method of Test for Surface Burning Characteristics of Building Materials and Assemblies, without the use of supporting material that is not representative of the intended installation.
• Materials which, when tested in the manner described in Clause 1.1 of CAN/ULC-S102, Standard Method of Test for Surface Burning Characteristics of Building Materials and Assemblies, melts or drips, or otherwise disintegrates and continues to burn on the floor of the test chamber.
• Materials designed for use in a relatively horizontal position with only its top surface exposed to air; or Thermoplastic materials.

The primary purpose of this Standard is to determine the comparative burning characteristics of the material or assembly under test by evaluating the flame spread over its surface when exposed to a test fire and thus establish a basis on which surface burning characteristics of different materials or assemblies may be compared, without specific considerations of all the end-use parameters that might affect these characteristics.

Our Interpretation of CAN/ULC-S102.2: RadonX is tested to meet or exceed the heat, melting, or fire resistance characteristics required for safe use in building construction per the National Standard of Canada.

A Quick Summary of the Ontario Building Code Regarding Radon Mitigation

As of January 1, 2025, the Ontario Building Code strengthens requirements for radon, making “rough-ins” mandatory in new homes. This allows for future activation if needed. Some municipalities have implemented more specific, stricter requirements for radon mitigation in new construction. RadonX products are designed to meet these requirements.

There are currently no legal obligations for existing homes, rentals, or businesses to add radon mitigation systems into their building unless there are high radon levels that need to be corrected. In the future, potential buyers may want radon testing done prior to a home purchase, which can be completed with an in-home monitor over a 90 day period. It’s best to do this testing during the winter, when your windows are closed. This creates a more accurate reading. Alternatively, you can hire a professional for a faster reading.

ASTM pipe refers to pipes that are made to the standards set by the American Society for Testing and Materials (ASTM). ASTM standards are guidelines that ensure that materials used in manufacturing are high quality and perform as expected.

ASTM standards specify the physical, mechanical, design, and installation requirements for plastic pipes, tubing, and fittings. These pipes are used in water distribution systems, waste drainage systems, and more.

SDR stands for Standard Dimension Ratio, which is a measurement used to rate a pipe's durability and working pressure capacity. It's calculated by dividing the pipe's outside diameter by its minimum wall thickness. A lower SDR indicates a thicker wall and a higher pressure rating, while a higher SDR indicates a thinner wall and a lower pressure rating.

SDR 35 is a type of pipe that's designed to be more flexible than Schedule 40 pipe. This flexibility makes SDR 35 a good choice for underground pipes, where they can bend with the shifting and settling of the ground. SDR 35 pipes are also lightweight, easy to install, and resistant to corrosion, cracking, and splitting.

When it comes to plumbing, one of the key factors to consider is the required pressure rating for your system. Choosing the correct pressure rating will help reduce the risk of pipe failures, expensive maintenance, and overall safety. Whether you’re working on a residential plumbing job or large scale infrastructure, we can help supply the best piping for your needs.

A pressure rating is the maximum internal pressure a pipe or component can safely withstand without failure. There are a few components that influence pressure ratings, which we’ve broken down below.

Pressure Rating Terminology

1. Working Pressure (PSI/Bar/PN): This is the maximum continuous pressure a pipe is designed to handle under normal operating conditions. It’s often expressed in pounds per square inch (PSI), bar (metric), or Pressure Nominal (PN) for some plastic pipes.
2. Burst Pressure: This is the pressure at which a pipe is expected to rupture. There’s typically a safety factor built in, meaning the burst pressure is often 2-3 times higher than the rated working pressure.
3. Standard Dimension Ratio (SDR): For some plastic pipes (like PVC), SDR is used to express the relationship between the pipe’s outer diameter and its wall thickness (SDR = OD/wall thickness). A higher SDR number indicates a thinner wall and thus a lower pressure rating. For example, SDR 26 has a lower pressure rating than SDR 17.
4. Pipe Schedule: This number (e.g., Schedule 40, Schedule 80, Schedule 160) indicates the wall thickness of the pipe. A higher schedule number means a thicker wall, resulting in a smaller internal diameter but greater strength and pressure resistance.
   • Schedule 10: Thin-walled, typically for low-pressure applications where weight and cost are concerns.
   • Schedule 40: Considered “standard,” used for a wide range of medium-pressure applications.
   • Schedule 80: “Extra strong,” thicker walls for higher pressure or increased toughness.
   • Schedule 160: The thickest standard wall, “double extra strong,” for very high-pressure requirements.

• Safety: The paramount concern. Undersized or under-rated pipes can lead to catastrophic failures, leaks, bursts, and potential harm to personnel and property.
• System Integrity: Ensures the piping system remains structurally sound and functions as intended over its lifespan.
• Longevity: Properly rated pipes are less susceptible to stress, fatigue, and premature failure, extending the system’s operational life.
• Compliance: Meeting industry standards and regulatory requirements for safe operation.
