Frontier Basement Systems Q&A

Do crawl space ventilation fans work?

Crawlspace ventilation fans or power vents causes all the humidity evaporating off the damp dirt, damp foundation walls, and hot humid air from the other crawlspace vents to be drawn to one central spot; the power vent itself. This always makes the area around the power vent more humid than the rest often creating mold and wood rot in the area. Ventilation is 100% climate specific. Ventilation works better in Arizona than Tennessee. Tennessee is too tropical and humid for ventilation to be effective. Air sealing the entire crawlspace off from all humidity sources is the only real solution.

How do you mitigate radon?

Mitigate means to lessen or make less severe, so to mitigate radon is to remove the gas from your home using a mitigation system. A typical radon mitigation system consists of a large-diameter plastic pipe that connects the air beneath your foundation to the outdoors. An in-line fan sucks radon-rich air from beneath your foundation and expels this hazardous air to the exterior. Instead of entering your basement or other living space area through numerous gaps and cracks in the foundation, radon gas is extracted from beneath your foundation before it can permeate into interior space.

What is a french drain and how does it work?

A French drain is a drainage trench filled to ground level with fragments of brick, rock, etc. It is designed to catch "Surface" water and redirect it, typically around a house, Good for stopping erosion, but not good for stopping underground water seepage. https://www.youtube.com/watch?v=xZaCzub5ZXw

What is a french drain?

These seems to be a lot of confusion on the difference between a french drain and a curtain drain. The French drain by definition is located at the footing of the foundation; it collects and diverts water from the perimeter of the home, alleviating pressure off the foundation wall. Typically it is a trench with gravel or rock that collects and diverts water from the foundation.

What is a radon system?

A radon system is comprised of a sump liner, a 4 inch diameter pipe connecting the flow of air through the foundation soil and liner out of the home by a exterior fan. By fully encapsulating or sealing the crawlspace or basement ensures that the radon is prevented from rising into the home and forced out through the system.

What is a sump pump?

A sump pump is an electromechanical device used to move water. This pump can be submerged in water and will move the water up and out of a basement or crawlspace.

What is involved in a good crawlspace encapsulation?

5 Steps to Encapsulation 1. Address any Water Issues Make sure to waterproof before you lay a barrier down. Do you have proper drainage? Do you need a sump pump? 2. Install a true vapor Barrier Be sure to use a plastic that is thick and durable Overlap joints, seal any leaks. Fasten properly to the block Wrap columns. 3. Stop Outside Air Seal crawl space vents with proper insulation and foam or caulking Seal around plumbing, electrical, or other lines. Invest in an insulated crawl space door and seal 4. Insulate R-10 rating on the walls & rim joist. Joist are the leakiest areas. 5. Control Humidity. Keep humidity levels below 55% Anything greater than 60% is a breeding ground for mold. https://www.youtube.com/watch?v=VWCfmddpS8o

What is radon inspection?

Once you have had your home tested for radon and received results of elevated picocuries the next step is to have an inspection to talk about installation options for a mitigation system. An experienced radon mitigation contractor will be able to provide installation advice, as well as more information about radon and why radon testing is so important.

What is radon testing?

Radon testing is to measure the picocuries (pCi/L) found in the air of your home. For a valid test result, the test must be performed under Closed House Conditions, for 12 hours before the test and during the exposure period. The test should be performed in the lowest area of the home, that could be used regularly. E.g. bedroom, play area or workshop. The test device should be left in place for at lest 48 hours. Once completed it should be sent back for analysis straight away or the results could be invalid!

What is the proper location of a radon mitigation fan?

A radon mitigation fan should be installed on the exterior of the home. This ensures that the fan remains clear of mud and water from the foundation and in the event of a leak, there won't be concentrated radon leaking into the home.
