    Felt550™ Has Two Significant Uses In A Crawl Space

    Puncture Strength

    The Felt550™ is made from virgin Polypropylene and woven into an lightweight and extremely punture resistant material. There is no organic material used when making this product so it will naturally resist mold and mildew growth. In fact, the Felt550™ was designed and engineered to be in contact with water and the earth 100% of the time. Putting all of these features together makes it perfect to use under a crawl space liner or vapor barrier to protect it from sharp stones, rocks and othe debris.

    Soil Gas Mitigation

    Crawl spaces are harsh environments and with that comes considerations in air quality. One of the most serious is Radon Gas, because it is a killer. The Felt 550™ plays an important roll in Radon Gas Mitigation. The Felt 550™ creates an air gap between the vapor barrier and the soil, enhancing the results of the active Radon fan(s). Allowing the fans(s) to keep a negative pressure on all parts of the crawl space floor and eliminating any "pockets" that seep the gas into the space.
    The Felt 550™ also plays a key part in mitigating other soil gasses that cause odor. As we continue to do research on the best ways to fix the problems with air quality, energy loss and moisture levels we discover new problems and their solution. One of those new problems is soil gas odor(other than Radon Gas). This problem is not everywhere and it has nothing to do with our vapor barriers causing the smell (other plastics have been found to contribute depending on their makeup and additives). Like with Radon Gas, the Felt 550™ enhances the results of the fan to mitigate the odor.

    For more information on this problem and how to fix it please call our office 877.379.7658.

    • Can be use on TOP of the liner for a "crawl way" path

    Our crawl space was full of sharp edged gravel. The 550 felt was the perfect answer as a barrier between the 12 mil vinyl and the gravel. Easy to install and seam. im

    It became almost like a cushion between the gravel and my knees. I would strongly recommend the use of this felt with any of the vinyl encapsulation product it made all the difference in protecting the vinyl.

    I used the Felt 550 to protect my vapor barrier from the crushed stone that lines my crawl space. I was very impressed with how strong it was. It was super simple to put down. I did put landscape staples through it to hold it down. It was challenging to get them through the felt. But a little hammering helped get them through. I really debated wether to use the felt but I am glad I did.

    I like this product for the big peace of mind at modest cost. It's almost impossible to be 100% certain you got all the sharp, poky things out of the dirt but this felt takes care of that. Plus your knees will thank you when you forget your knee pads. The added thickness is a real plus and shows this company cares about quality and continual improvement. One last benefit: if you ever need to deal with radon gas, the felt makes a great air transfer layer u dear the vapor barrier.

    Decided at last minute to do this as added protection and absolutely happy I did. Builder had used 1-2" of lime rock to cover area and didn't realize just how sharp and damaging those rocks can be until getting in and doing the work. Strongly recommend everyone to consider this small investment as likely to save entire job over time!

    Cons:
    Very puncture resistant. It was easy to cut with a utility knife, but if you wanted to start a new hole in the middle of a piece with the knife it took some effort. The overall durability of the product remains to be seen, as it has only been installed for a week. Soft on the knees for crawling around and should protect the plastic from any tears.

    Felt 550 Underlayment

    Durability:
    Quality:
    Recommend:
    Pros:
    Cons:
    Ordered and received 5'x100' felt for installation in my home, as a consumer. It came shrink-wrapped on a roll, probably weighing 25 lbs. I was a little disappointed to find the product measured around 50" wide. It was hardly 5 feet wide as advertised. We didn't measure the length of product, but doing some rough math it probably measured 120-130ft or so. In either case it exceeded the 500 sq.ft. I expected.



    I was concerned the narrow product would have a tendency to shift under foot/knee traffic in the crawl, prior to and during installation of the vapor barrier. Installation was simple. We secured the strips together with Gorilla Tape and it held very well. There was virtually no shifting. I would recommend this step.



    Strength, thickness and cushioning provided by the felt are impressive, and will absolutely protect your vapor barrier from any sharp objects in the crawlspace. I would argue this product is probably more important than buying a high-dollar and/or high-mil barrier. We covered it with 6mil visqueen.

    <p>Product is great but I only received 41 ft of material. Not even sure how 9 ft of material can be missing. Needed about 45 ft of material to cover crawlspace. An area of 4x4 feet of my crawlspace has no material over it. Unfortunately I can only give 3 stars for quality because the roll i received did not contain the amount of material advertised.</p><p><strong>CrawlSpaceRepair.com Response- </strong>Often when this happens it is due to inaccurate crawl space measurements and/or rounding off. Each roll is weighed prior to shipping to insure every roll is at least the minimum stated length. We contacted this customer after he submitted this review and came to an understanding that we were both happy with. </p>

    I have the crawl space from hell to encapsulate. The ground is covered with this awful stone that digs through your knees. The 42 550 was critical to my success. Why go through all that work of encapsulating and not take every effort to protect the vapor barrier from damage. I have 1800 feet of crawlspace floor and one third has a clearance of around 16 inches. Putting the 42 down first made it less nasty when I had to belly crawl on the floor to put the 12 mil vapor barrier up on the uneven brick foundation.

    I was pleasantly surprised how strong this is. I tried to tear it or poke holes in it, but I couldn't. I put it on top of rough edged stone, before I laid down the vapor barrier. It's much better than any of the alternatives I was considering. I'm very satisfied with it's performance.

    I usually don’t respond to reviews and stuff, but feel compelled to in this case. I was dealing with a damp crawl space for years and could not figure out what to do about it. It destroyed my floor by the rust from the nails staining through the linoleum. I found the CrawlSpace Solutions website and I can’t say enough great things about my experience with them as a company and the products I received... AWESOME and AMERICAN MADE. I had my order in 3 days as promised and what tough material this is!! Thank you very much, Larry, for all the instruction and advice. 110% impressed!

    I used all your products including the 42 550. I used the 42 in the event 88 was identified as a problem. I will always use the 42 on future jobs. Even a very well prepared crawl space will have small rocks and gravel that cause no problem when the 42 is used.

    Rating:
    Pros:
    Cons:
    1) GOOD: This is not like roofing "42" , and shouldn't be. 42 has an organic fiber base which will decay if continuously wet, as underneath a vapor barrier. This synthetic product is just what is needed as a vapor barrier underlayment. 2) OK: I got this to protect my vapor barrier from sharp-edged gravel which was already covering my crawlspace floor. As such, this product is OK, but not as thick as I expected. It is like an extra-thick landscape fabric.

    The 42 was and is a must for installing the vapor barrier. I am so glad I did my research and found it. I can see where the 42 protects the plastic from sharp objects. It also helps to keep the dirt from getting all over the top of the plasitc during installation. Awesome product. Thanks Randy
