Recently, I have heard about a local foundation repair contractor’s claim that gutters and drainage are a viable alternative to the MoistureLevel Smart Foundation System. While I have always maintained that maintaining proper drainage and limiting the moisture intrusion under a slab on houses built in the arid Southwest are a good thing and should be encouraged, it alone will not solve the problem. We recommend those techniques to customers as a method to control additional moisture getting under the slab, but not to correct existing damage.
What I don’t agree with is that they are a viable alternative in lieu of a MoistureLevel System, and the logic is fairly straightforward. The point that I want to make is that gutters and maintaining proper drainage really has no immediate, large effect on the area that is experiencing the problem….. the place where the moisture accumulates the most, the center of the slab.
