Concrete Moisture Control Systems

#1
We are doing some construction with some potential moisture issues in some slabs and some folks recommended using some moisture control sealants to solve the problem prior to finished floors.

The sub recommended either Koester or Synthetics International.
Anyone have any experience with these manufacturers.

Thanks

Drew,

Where are you? Be careful of subs who recommend moisture products because those two products are not equal. In my opinion, they are at different levels.

Adam @ Synthetics is one of the best salesmen I've ever met. His sales software is amazing, he can track and follow up amazingly well - I could learn a lot from him. But I can tell you that I've passed on some major projects with Synthetics on the concrete. He has a broad spectrum of product. They aren't all the same. And as a flooring distributor I've had to really put the hammer down on subs who don't know the difference.

For me, Koester is the gold standard here in my part of California. When the entire floor comes up, and the hospital shuts down, and everyone lawyers up, and then the lawyers consultant up, the consultants always write the spec along the lines of:
Koester VAP 1 2000 or Ardex MC1 or Mapei EMB or equal.

"Or Equal" - a phrase I HATE in architecture. Nothing is really equal but I believe what you need to look at carefully is the Perm rating.

In my area the Koester rep is the expert. He's really been a beacon for me on doing things right or not at all. He continues to teach me a lot. When we have a problem I turn to him immediately.

I've never had a failure over properly done Koester.

And you don't have to take my word for it. Look at who's logo is on this document. They are the scientists for the Portland Cement Association and you do what they say period, the ultimate consultants. http://www.koesterusa.com/Testing/ASTM-E96-Results-for-VAP-I-2000-andVAP-I-2000FS.pdf

Yes I have experience with Koester. As Eaadams said, it's in the gold standard classification.

Please clarify your issues and I know we can help you out here.... Smile

Have had experience with Koester and Ardex. Both are good products. the key is to do the prep correctly and apply the product to Mfg specification.

Oops, I should say I'm a certified applicator of Koester and Ardex, and one of the first Nora Mitigation applicators in the US. (yea! nora!!! )
And Ray is 110% correct that prep is the most important part of any project. I am on every job my company does and I certify every part of each step. I go as far as using stop watches to time mixing and laying the ICRI molds on every floor to verify CSP profiles. It is routine for my guys now and it doesn't take much time to guarantee it's done by the book.

You know my background Ray, lifetime warranty with no excuses. It was always in the prep or the installation so let's check things out then double check, and then follow the directions....
Then if it goes wrong, at least my rear is covered as well as it can be... Big Grin

I completely agree with your statement about the tree chasing the house, but I don't think the fish hook square box ladder thing is correct.... Perhaps Eaadams or Stephen can help here.....
