I have read many articles on waterproofing ICF basements, like what I will have on my home, walkout basement.  I recently came across this product, Eco-Flex and wanted to hear if anyone has used it, their opinion on it, etc...

If it is proven at all, this could seriously be a strong product for any and all ICF waterproofing.

I have sprayed loads of this stuff years ago (2 of the four pictures on the front web page are my jobs) Setting up is expensive, purchasing a sprayer is several thousand dollars, no painter in his right mind is going to loan you his, and you will never get it clean enough to return to a rental center to there satisfaction, also most painters and rental centers only have small sprayers and you need the Big Daddy to spray this product, I had a Greco Mark V with a .035 tip (That's huge). The product sprays well, but you must check and foam fill any seams in the ICF greater than 1/8" as the product will not span the gap. We found you must spray two coats on the wall to acheive the sufficient mils needed, if you try and do it in one coat it will sag and run on you. It is a two man operation, one to spray, the other to keep the product loaded at the sprayer machine. This is a lot faster than peel and stick once you get the hang of it, but remember, the applicator must wear at a minimum a mask and eye protection, I also recommend a Tyvek type suit to keep your clothing clean, they don't generally need to be waterproofed, also keep the sprayer clean when finished or you will be fighting to get it going on the next job, the hoses will be full of waterproofing material. They do say you can use a roller to apply the product, it is somewhat difficult to roll as the product is extremely thick. When finished I also suggest a drainage membrane (Delta or similair) prior to backfill. The product did have Ontario Building Code approval when I last used it, check with your local inspector for their requirements. Now for the million dollar answer, yes I did make money with it, after four basements (each 3500-4000 sq.ft.) my equipment costs were covered, this is based on what I used to pay a competitors product to be sprayed on my walls by others.

Everything Chris said is absolutley correct, I have been using this product for two years and am very satisfied with it. The tyvek suit is a must the first job we did my wife burned my clothes after this she was not going to allow them through her washer.
The only thing we do different than Chris is the seam issue we go around first and fill the seams with the product and then proceed with our two coat coverage.
By the way Chris we converted an old fuel barrel laying on its side on a cart with a low speed agitator, we mix the product up and dump it in the barrel 20 gallons at a time, that is hooked to my four wheeler and also has room for our sprayer. One person can do the job fairly efficiently, as long as he remembers to keep the barrel lin a position so the syphon end of the sprayer is always at the low point.

We use it on every basement, and like it. We used to spray it with a commercial airless, but without running water on most sites, cleanup becomes an issue. We roll it on most times now.

PS. NEVER put your clothes in the dryer afterwards.

I'm glad you guys have had good success with this type of product. Personally I prefer air-gap membranes, it just goes to show that ther are a varity of professional ways to tackle a project with different products. How long does it take to roll (man hours) a typical 1500 sq ft of product? What is the cost per sq ft of product?

Dave

good catch Dave, we always still use an air gap on top of the ecoflex. Its backfill protection, backup waterproofing, both systems for about the same price as peel and stick.
Rolling gets far better coverage than spraying, and one must brush all the seams anyhow.. Two of us with rollers applied two coats of Ecoflex on a 2400 sq. ft. basement in four hours last week.
