Basement Waterproofing in St. Louis

Water in a basement usually comes from one of three places: the joint where the wall meets the floor, cracks in the wall or floor, or water pushed up from below by saturated soil (hydrostatic pressure). A good waterproofing plan starts by finding which one it is.

What the work can include

• Interior perimeter drainage that collects water at the footing and routes it to a sump
• Exterior excavation and membrane on walls where access allows
• Wall vapor barriers to manage seepage and humidity
• Grading and downspout corrections that cut the water load at the source

Questions to ask any contractor

• What is causing the water or movement, and how do you know?
• What exactly is included, and what is not?
• What does the warranty cover, and is it transferable if I sell?
• Do you pull permits where required?
