The basement in our house has concrete floor with cinder block walls. It already has perimeter drain as well as sump pump..However we have noticed lot of dampness in the walls lately as well as musty smell which i believe is a sign of mold/mildew. During Irene we noticed cracks at some places in basement which we will have to seal to avoid water from coming in. We are planning to apply waterproof coat in the inside and get mold treatment done. Also are thinking of regrading around the house and rerouting the gutters and down spouts away from foundation walls. We were also thinking of putting a 12'' wide cement walkway surrounding the exterior of the house to avoid any water penetration. Do you think that would be sufficient vs. excavating around the house to put in a drain? We live in Parsippany,NJ.
Thanks for your insight into the matter.
