Dimpled drainage matting, placed between the vapor barrier and the ground, improves drainage and significantly enhances the durability of the liner. Think of dimpled drainage matting as a durable sub-floor between the liner and the gravel or dirt crawl space floor. It’s high-density polyethylene (HDPE) composition provides good resistance to water pressure and aids in drainage. The dimples serve to quickly direct water to the footer drainage system, and provide a chamber of air between matting and the surface it is applied to. Drainage matting is composed of recycled materials and is considered a GREEN product. Meets/exceeds ICC-AC114: Acceptance Criteria for Rigid, Polyethylene, Below-grade, Damp proofing, and Wall Waterproofing Material.
Specs:
- Length: 3’11” x 35′

- Thickness: 0.2952″
- Compression Resistance: 729 lbs/in

Important Note: For the drainage matting to function as intended, proper installation is necessary. The flat side of the drainage matting should be flush with the vapor barrier, and the dimples should be pointing down against the surface you are covering.

We encapsulated a small gravel crawlspace without dimple mat. We used it on the larger one and it made a big difference. Once the dimple board was on the gravel, doing the rest of the encapsulation was so much easier on our knees, and hands, and… We could instantly see how much it added to the durability of the liner.

I have purchased similar drainage matting from one of your competitors and the shipping cost more than the material. I needed more and came across your site in a recent search. Your material appears to be identical and you sell smaller rolls which saved me a considerable amount in shipping. I hope more people find your site and save money as well.

What I wanted. I wasn’t sure what the product was made of when purchased. It is a flexible plastic, easy to work with and customer with scissors it razor knife. Suited my application perfectly.
I order 3 day shipping and the owner emailed and called me said it wasn’t necessary to pay the extra shipping cost. Due to the distance I was from the warehouse and I will receive it in 3 days
.. Great customer service…. Thank you..DIY.

The drain matting was exactly what was needed to begin the encapsulation project of my dirt covered crawlspace. The quality is excellent and it was easy to work with.

It’s hard to give a review on just one product from Crawlpace DIY because as a whole everything I received was great. Great advice when I called. Great products and great return service. Do it yourself!! And the drainage mat was easy to work with and was in manageable rolls to handle. Thanks!

I have an unfinished basement that gets wet on occasion. I wanted something that would allow air to get to the dampness to help it dry while allowing my feet to stay dry when I walked around or worked in the basement. This product worked perfectly. I can also store some things that I couldn’t before, and not worry about water getting to it. It was easy to install. Probably the hardest part was taping the sections together, and that wasn’t hard at all.. Depending on the size of the project, it’s probably a 2-man job.

This product was easy to install and provides a pathway for water to escape from being trapped against your foundation. Highly recommended for areas where you have a high water table or hydraulics.
