Filling large voids in the masonry.

How do you stop water from coming through a dry laid granite fieldstone foundation - - without excavating the exterior fill (and plantings, and pavings) to the depth of the footings? Did you know that a hydrophilic crystalline admixture can be utilized to waterproof a fieldstone foundation - - from the inside? The S+H Landscape and Sitework Division developed a basement waterproofing technique in which they introduce such crystals into the stonework. These crystals grow in the presence of water, expanding to fill the capillaries in the foundation walls. This prevents water from entering. If your walls are leaking or your basement is wet and you’re seeking a long-term solution, consider this method.
