Waterproofing Frequently Asked Questions

A wet basement, water stains, calcification build up, foundation cracks, and standing water are the most common warning signs of basement flooding. Learn more about common signs here: 4 Signs of Basement Flooding

If your basement is flooding, the first step is to locate the source of the water. Common places to look are; foundation cracks, plumbing, appliances, sinks, etc. If the water is coming through pipes, shut off your water and call your plumber right away. If the water is coming through a window or foundation crack, call Zander Solutions and we’ll be there in no-time for a free consultation.

In most cases, your basement does not need to dry before waterproofing can be completed. We will install drain tile systems when there is up to one-inch of water standing to help drain the water. If you’ve got foundation or window cracks, Zander Solutions will complete crack injections to stop the flooding, and water does not need to be gone before this work is completed either.
