Radon Resistant New Construction is Simple in Oklahoma with Enkavent

Radon Resistant New Construction in Low-Rise Multi-Family and Individual Homes with Colbond EnkaventUse Enkavent® as a Radon Prevention and Mitigation Barrier System

RRNC ( Radon Resistant New Construction ) in Oklahoma has become an accepted norm for Radon Gas prevention and mitigation in the US construction industry and the organizations that represent and govern them as well as federal, state and local agencies. The term RRNC refers to building a new home with a Radon Barrier and venting system installed during construction with the emphasis on successful prevention and then reduction built into the structure rather than added later. RRNC proven Colbond Enkavent provides an easy and cost effective solution for radon professionals and builders to build in a combined radon and moisture control barrier simply at the best possible time - before the slab is poured. This is a double security for builders and contractors – usually on its own the use of Enkavent provides prevention and significantly reduces the ingress of Radon into a new structure – but if subsequent measuring of the Radon levels detects excessive readings, then it’s simple to install additional fans to aid ventilation and Radon Mitigation (or reduction).

RRNC can save lives when a structure is completed and a radon fan can be added if necessary to reinforce the elimination properties of the system. Enkavent, having recycled content, also offers Green Building benefits by helping to meet NAHB, EPA/Energy Star, U.S. Green Building Council LEED-H requirements, and an increasing number of state or local regulations. Building in Radon Resistance and elimination with Enkavent from Colbond is a win/win/win scenario for the builder, the radon mitigator, and the homebuyer, being simple to use, tried, tested and most importantly cost effective.

Enkavent 6128 is a radon venting product specifically manufactured to mitigate (reduce) radon gas from under concrete and basement slab construction, and to help prevent Radon Gas levels getting above the 4 pCi/L measurement deemed potentially dangerous. Enkavent provides a sustainable airspace that intercepts radon gas before it seeps into a basement, crawlspace, or through the slab and has proven crush resistance. Better than a series of venting pipes built into the slab underlayment, Colbond Enkavent from ICF & More, Oklahoma City is underlaid under the entire surface of the slab, allowing a 100% free draining substrate coverage for both humidity and Radon Gas – raising the percentage effectiveness.


  • Reduces radon level up to 97%
  • Has Proved Effective since 1985
  • Is Strong enough to sustain the load of a 12" concrete slab
  • Exceeds the requirements of floating slab construction
  • Easy & quick installation – no digging, no extra gravel, unrolls flat
  • Cost-effective – allowing Radon Prevention and Mitigation for new construction at an affordable price

How the Enkavent Radon Prevention and Mitigation Membrane system works:

  • Enkavent Radon Barrier actually permits radon to permeate through the filter fabric and into the airspace created by the recycled content nylon matrix.
  • The Airspace stays open because the filter fabric holds back gravel and soil.
  • Natural airflow passing through the Enkavent matting directs radon to ventilation pipe openings by the passive result of Radon Gas being much heavier than air and flowing naturally downhill – much as Enkavent also drains excess moisture from under the slab.
  • The unwanted and dangerous Radon Gas is routed outdoors.

Install a Radon Barrier and Reduction system when Constructing new Homes and save lives!

Install a Radon Barrier and Reduction system when Constructing new Homes and save lives!Even in small quantities, the radioactive gas radon has been proven to be dangerous in Oklahoma and surrounding areas; it is known as a silent and deadly killer and for good reasons. Odorless, colorless, and radioactive – Radon is a gas that can enter into any home unseen. Radon is produced through the breakdown of uranium in the soil, often located under a homes slab and foundations. Despite little press coverage, Radon is second only to cigarette smoking as a cause of lung cancer deaths in the United States. Because radon levels are influenced by numerous factors interacting — such as, soil type and moisture, how airtight the structure is, the type of heating and ventilation system, movement of air and groundwater, air pressure, and the lifestyle of the occupants—the only way to know if a home has dangerous levels of radon is to test it – impossible to do prior to or during the construction a new home or building. This is where installing Enkavent under a basement slab makes perfect sense when building a new and modern well insulated home – prevention is better than any retro-fit cure where Radon Gas is concerned – especially as a new and modern, well insulated homes air transfer rates are much reduced. 

To check whether an area of new construction is likely to be effected by Radon Gas, see the map below or in more detail at th United States Environmental Protection Agency.

Studying the dangers of Radon exposure safely is both complicated and expensive, so have limited research into its properties. Chemists at the University of Pennsylvania have recently and for the first time measured how well radon binds to a molecule, paving the way for future research on it and other noble gasses.

For our protection, and effecting in particular the new construction industry, on January 11, 2013, the American National Standards Institute (ANSI) adopted a new building standard, RRNC 2.0, Reducing Radon in New Construction of 1 & 2 Family Dwellings and Townhouses. RRNC 2.0, a "Model Code" standard for the installation and testing of new construction radon systems, is a consensus standard developed by an American Association of Radon Scientists and Technologists (AARST) Consortium committee of radon professionals, builders, architects, consumer advocates, and state and federal government officials.

The purpose of this new AARST/ANSI standard is to further radon mitigation and reduce exposure – increasing safety in the United States by providing a model building code to achieve indoor radon concentrations of less than 4 pCi/L [148 Bq/m3] in new construction of homes. It is a "code ready" standard that provides a significant improvement over the IRC Appendix F "Radon Control Methods." 

Adherence to this new building code will reduce not only the health risks but also financial risks to builders and bankers who are concerned about building homes with long-term radioactive liability. It is estimated that over 8 million U.S. homes and 70,000 classrooms contain high levels of radon, which is a huge liability claim risk for any constructor or their insurance to bear.
