Waterproofing an older concrete foundation
Yes, I am talking about waterproofing from the outside. A bit of water as well as humidity come through the walls. You say to power wash the foundation and install the waterproof membrane 4" above grade and down on top of the footer and over the bottom edge. But what kind of membrane is best for an older rubble concrete wall? One company I spoke to proposes the Platon product (a rigid panel that needs to be nailed or screwed to the wall) and the other the Bakor product (a mastic that is brushed directly onto the wall), as I explained in the first post. By the way, this house, built circa 1927, has no footings. I am told this is typical for this area at that time. Also, what is the goal of power washing?
Thanks again for any advice.
