The "plugging" that I am referring to is in the very small drain holes cut into the cement crock. The (2) openings were crudely cut into the sides of the crock and were approx. 2" X 3". Large river rock had allready plugged the small holes one week after installation. It would seem that over time, much of the gravel base under the new slab would find it's way into the crock creating a hollow beneath the floor, possible erosion under the floor and eventually the slab will fail. Secondly, the drain holes were cut below the "high" float level which will result in continuous pump operation with little opportunity to cycle and cool down when it rains. I rarely see any "make-shift" sump systems here. We are serious about foundation drainage here in "Lake Country" Wisconsin. Full basements are the norm. Basement repair companies are very busy here as for some reason alot of basements here have moisture issues. More and more homeowners are finishing their basements now a days, it's the most cost effective way to add living space. This particular basement will never be finished, it's a small area just large enough for laundry, etc. I was just dissapointed to see a new system installed in such a temporary and poorly designed fashion considering the proximity to the large river at back lot line.
