I always recommend Xypex as an admixture whenever there are potential
water intrution issues. As a G.C. I also had good success using it as
a topical coating. Great stuff. (However in my engineering contracts I
specifically refuse to accept any responsibility for waterproofing or
venting. Too much potential for lawsuits.)|

At last year's Wyoming
Engineers Society Convention, I was introduced to a line a products by
Xypex, who apparently specialize in water proofing of concrete. They
have several applications of their product, one of which is a slury
application. This might be something that you can incorporate into
your project. From what I gathered, it's a crystaline product that is
constantly hydrating and expanding itself as water infiltrates and
cracks grow. There are several cities that have approved the Xypex
products as a concrete admixture for it's leak-stopage characteristics
and abilities. If you have doubts of the Sika, you might want to give
this stuff a look see. Check it out at: http://www.xypex.com/
Product Disclaimer: I am not
affiliated with this product in any way, shape or form, nor have I had
the opportunity to specify it on any of my projects. Therefore, I
cannot speak for it's performance. I am just relaying information that
was given to me.

I specified a Sika epoxy product sealer for a subterranean
parking garage floor that leaks water to the level below per the Sika
rep recommendation, but the contractor, who has done dozens of garage
floor treatments, is advising against this product. He claims that Sika
has been sued over the failure of this product, that it discolors and
peels away and does not stop leaking through the concrete decks. He
recommends a urathane coating. Anyone have experience with garage floor
