Liquid Rubber Waterproofing

"ECO-FLEX - an economical, tough, flexible liquid rubber waterproofing membrane for concrete and block foundations that is safe and easy to apply"

rubber waterproofing material Eco-Flex is a water based, cold applied, highly flexible liquid rubber waterproofing membrane. Aquaseal has developed this exceptional product for both ICF (Insulated Concrete Forms) and the standard construction industry, using the very latest technology. Eco-Flex is solvent free and non-flammable, and forms a highly flexible monolithic waterproof membrane. It has excellent adhesion properties, not only on ICF forms and EPS blocks, but also concrete (both new and existing), curing to form a water and vapor proof coating. It can also be used beneath tile in shower and toilet areas, or as a water and vapor barrier under a concrete subfloor. Eco-Flex rubber coating is not only #1 in quality, but is also offered at a very competitive price.


"I would just like to express my gratitude about your product. When it came time to apply the Eco-Flex......the sealer went on beautifully and I didn't have to mix it very much. I just stuck a 1/2" matted roller in the bucket and went to town. I covered 110 feet of an 8 foot wall in 40 minutes. I think this product is superb and would highly recommend it. Thanks again!"

I will be using Eco-Flex on all my EcoBlock ICF homes. I am also now using the new Aquaboard on my foundations which maybe exposed to rough back-fill material as added protection."

For areas located in Northern climates we offer

Eco-Flex WF (Winter Formula)

With the same great qualities as Eco-Flex, Eco-Flex WF contains a small amount of 'clean solvent' which helps it cure in temperatures down to as low as 20F, but it is still environmentally friendly and VOC compliant in all States. With the availability of this new product, you can continue to waterproof foundations through the cold months.
