We come across this situation more often then we should. A company will come and dig a hole, put a bucket in there with a few holes, stick a sump pump into it and call it a day. Unfortunately, unless proper drainage is dug and installed that directs any water that enters the crawl space to the sump pump, all that work is useless. Fortunately, our moisture control specialists are trained professionals in proper drainage technics. They will make a plan that will ensure if any water enters the crawl space it gets diverted to the sump pumps to be pumped a safe distance away from your home! Here are 2 pictures of how to properly install drainage and install a sump pump.
