<div>Hi Annie,</div> <div>I built a new garage/shop space a few years ago and the foundation is a cement slab with 6" cement blocks set all the way around for the walls to be "set" on. This was a stick built do-it-yourself deal from the home center(Menards) where I designed it as I wanted it to fit my land and situation. It is set 3 feet in from my northernmost property line which is the building code here. My neighbor's garage is set 3 feet in from his southernmost property line so between the 2 buildings is a 6 foot area for the snow to build up both from snowfall and the snow sliding off of both roofs. The first spring the water flowed through my building almost as if it weren't there! The blocks, of course weren't waterproof and neither was the mortar or the slab. </div> <div> </div> <div>That summer I dug up all around the perimeter and exposed the foundation washed or wirebrushed the dirt and loose cement off and coated it with Drylok by UGL which is a cement sealer and waterproofer that is guaranteed for, I believe it is 15 or 20 years. </div> <div> </div> <div>I have since seen other companies offering similar products gauranteed for longer time periods, Zinsser is one that comes to mind. Some of those can be applied to the interior of the cement with the result of stopping water penetration. If you have cracks or holes in the foundation there is waterstop cement that can actually be used while the water is pouring in(so they claim).</div> <div class="gmail_quote"> </div> <div class="gmail_quote">Hope this helps! </div> <div class="gmail_quote"> </div> <div class="gmail_quote"> </div> <div class="gmail_quote"> </div> <div class="gmail_quote"><br>><br>> Oh, and remember my question about dampness in shop floors?  Well, it<br>> turns out that the previous owner was minimiazing a bit when he told me<br>> about it. There's a small (but still manageable) flood coming through the<br> > foundation as the snow and ice melt.  Aaargh.  Thank goodness for shop<br>> vacs!<br>><br>> Annie<br>><br>>> >><br>>>><br>>> "Annie Grieshop" <<a href="mailto:annie@allthingspiano.com">annie@allthingspiano.com</a>><br> >> Sent by: <a href="mailto:pianotech-bounces@ptg.org">pianotech-bounces@ptg.org</a><br>>> 02/04/2008 12:41 PM<br>>> Please respond to<br>>> <a href="mailto:annie@allthingspiano.com">annie@allthingspiano.com</a>; Please respond to<br> >> Pianotech List <<a href="mailto:pianotech@ptg.org">pianotech@ptg.org</a>><br>>><br>>><br>>> Mike<br>-- <br>Age is an issue of mind over matter.
