Hi, this is my first post after joining the forum (and was impressed this site has an iPhone app as well). Was looking for some advice on a new house I bought in SC. It is a one story house on a crawlspace. In the back, the previous owner installed a concrete patio that runs up against the foundation. In one spot, water collects against a vent well and is causing water to leak into the crawlspace through the vent. Wanted to get some advice. Looks like the previous owner used a sealant at the interface that has since eroded away. Any suggestions for a product that would give me a good seal at the patio/steel vent well/brick interface? Should I also consider sealing the whole brick foundation on that side of the house where I have the problem? Some pics attached. Also...we already have that specific crawlspace vent closed. Thanks!
