What Can Be Done to Prevent Concrete Pitting, Staining, and Flaking? 

As a homeowner, you should absolutely avoid concrete pitting, flaking, and staining around your foundation and exterior concrete structures. They not only make your home look old and unsightly, but they also undermine the concrete. Improving the drainage and moisture control in your basement is essential for indoor concrete. Protecting outside concrete is marginally more challenging. There is little that can be done to preserve the slabs from the elements other than to cover them with waterproof sheets. Improving your yard’s drainage system so that water does not run toward your concrete slabs can be of assistance.
