DIY Radon Mitigation Coating

How Radon Gas Enters Homes

Radon mitigation is important because radon is an odorless, colorless, tasteless radioactive gas that forms from the decay of radioactive elements, such as uranium, in rocks and soil throughout the world. Scientists and doctors have proven that it causes cancer. In fact, the Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. Only smoking causes more lung cancer deaths. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.

Normally, some of the radon produced in the ground migrates to the surface and becomes a natural part of the air we breathe. Under certain conditions radon may seep into buildings through cracks and other openings in the foundation walls and floor and accumulate to very high concentrations. Radon dissolved in the groundwater may also enter a home through the water supply system and contribute to the overall concentration of radon in the indoor air.

Radon Facts from the EPA

  • Radon is responsible for 21,000 lung cancer deaths a year in the US
  • Radon is the second leading cause of lung cancer
  • 1 in 15 homes in the US has elevated radon levels

Permaflex, LRB (Liquid Rubber Base), and TAV (Thickening Activator)


Permaflex is the top coat that seals basement walls and floors. It’s also functions as a first priming coat when using LRB (Liquid Rubber Base) and TAV (Thickening Activator). The priming coat fills pores, pock holes & pinholes in the substrate.

These two products work together to patch and profile any joints, seams, cracks, holes or rough areas. Products are packaged separately because different mixes are required for different applications. For example, a 1-inch diameter caulk bead of LRB/TAV (1 part TAV, 2 parts LRB) mixture is applied where the wall meets the floor.

Do It Yourself Radon Elimination and Basement Waterproofing System Combined!

SANI-TRED is the only problem radon elimination system available today. All other companies and systems ‘mitigate radon’, in other words attempt to reduce radon by redirecting it before it enters or after it already enters the basement. DIY radon mitigation systems and radon abatement systems are indirect and ineffective methods of dealing with intruding problem radon gas. Radon gas can enter the basement along with water, moisture and vapor. Radon remediation systems are not intended to stop radon, water, moisture or vapor therefore your basement will still be left susceptible. Radon gas removal system and radon reduction is a thing of the past. We eliminate NOT mitigate.

The Definition of Mitigation: To act in such a way as to cause a condition or offense to seem less serious or to make less severe or milder.

The Definition of Abatement: Reduction or interruption in the intensity or amount of something.

With SANI-TRED waterproofing products you will NOT mitigate, you’ll ELIMINATE! Sani-Tred products stop problem radon i n its tracks forever regardless of the current condition of the basement. Sani-Tred products do not work some of the time or most of the time, it works EVERY TIME. Sani-Tred’s Unique Product Qualities are: Flexible Penetration®, Permanent Elongation®, and Elongation Memory®

    -- Apply a 1’’ diameter caulk bead mixture where the wall meets the floor.
