“Our house is about 60 years old with a cinderblock foundation. We are finishing our basement and need to address some water issues. Our basement is very dry; the previous owner said it had not flooded in the 25 years she lived here, and we’ve had only minor issues with water in extremely wet weather. The walls in the basement have been painted by previous owners, probably with a waterproofing paint, but I really don’t know.
In a number of areas the paint has chipped off or been damaged by lime buildup, leaving areas of cinderblock exposed. We have not had any water coming in where the old paint is chipped or missing, however, and I was wondering if that would be an indication that there is not likely to be significant water buildup.”
Water damage being a creeping menace to a house’s foundation will be familiar to North Carolinians, especially those from Charlotte. The city’s precipitation fluctuates between three and a half inches to roughly four inches all year round; ice storms and sleet mixed with rain have the potential for thaws that seep into any crack. When you are as concerned with your house’s basement and foundation like the above homeowner is with his, consider help from basement waterproofing through Charlotte, NC contractors like Blake’s Waterproofing.
The entire basement should be inspected for puddles out and about, which may have manifested after a particularly wet day. Only when enough data has been amassed can the contractor give you a full quote. The sender explained that the seepage in the basement’s wall floor joint was not enough to build up into a flood, but it did leave a ten-inch wet mark on the wall that was six inches at the widest.
The water buildup on the foundation may be a matter of external soil grades, which your contractor can address. Stetler said the entire grade around the house should be checked for positive values; a flat or negative grade has the potential to have the water build up and stress the foundation. However, your contractor may not recommend waterproofing the wall-floor joint if there’s a remote chance that water would fill up the cinderblock cores.
The seepage can actually be the tip of the iceberg and a contractor like Blake’s Waterproofing may recommend further options, such as foundation repair in Charlotte, NC. Stetler said a solution for the reader’s problem involves setting up insulation covering the top of the cinderblocks to at least two feet below grade.
