This past week we received a call from a premier real estate investment company that has a basement leak behind their finished basement walls in their corporate offices. I suggested that they open the wall so we could see what part of the granite block wall was leaking. They opened the wall and saw water seeping and squirting from the blocks. The investment company decided that they would try to stop the leaks themselves. Within in three hours I got a call back. They explained the situation to me and sent pictures by e-mail. The pictures showed that they tried to stop the leaks between the granite blocks and where the granite blocks meet the floor with hydraulic cement. Clearly their attempts were not working.
When we arrived at the job site the water was still leaking. We had to remove the gobs of hydraulic cement from the wall so we could see what we were dealing with. In this situation we used a combination of waterproofing methods to solve the problem. We used oakum imbedded with our patented closed cell polymer resin, injected polymer resin with an electrical pump, and applied a crystal /quartz based material to the granite foundation basement wall. I am happy to reports we stopped all foundation leaks.
As in life, waterproofing knowledge, experience, and patience is what is needed to solve most problem. For any of your waterproofing or masonry repair needs call A-1 Foundation Crack Repair Inc at 866-929-3171.
