Most of Grandview went up between the 50s and 70s, a lot of it on concrete block. Fifty years of Jackson County clay pushing on block gives you horizontal cracks and bowing. Common out here, and very fixable.

Wet basements in Grandview are almost always a soil and drainage problem. The clay around Jackson County doesn't drain. It holds water and pushes it against your foundation walls for months after every storm. We stop it at the source.

Frequently Asked Questions — Basement Waterproofing in Grandview
Why do Grandview basements leak?
The Jackson County clay holds water against these mid-century block walls and forces it through the porous block, the mortar joints, and the floor seam after a storm. Many of these homes also have gutter and grading issues that dump water right next to the foundation, which makes the leaking worse.
What's the best waterproofing fix for a Grandview block basement?
An interior perimeter drain tied to a sump pump, which collects water at the floor-wall joint and pumps it out. If the block wall is also bowing from clay pressure, we stabilize it first, because waterproofing a moving wall doesn't last. We check for both during the inspection.
Will fixing my gutters help the wet basement?
It's part of the solution. A lot of Grandview water problems start with downspouts dumping at the foundation and grading that slopes toward the house. We address that along with the interior drain so the soil isn't constantly saturated against the wall. Fixing the cause matters as much as managing the water.
How much does basement waterproofing cost in Grandview?
A crack injection is relatively inexpensive, while a full interior drain and sump system runs higher depending on the basement. Wall stabilization, if needed, is separate. The inspection and written estimate are free.
