I am volunteering at a local religious organization, rehabbing a dilapidated 40 year old back porch. I've enclosed it, put in windows, doors, wiring, insulation, sheetrock, and now for the floor. Someone added 2 1/2 feet by 10 foot extension onto this porch, using a very poor mix of cement. It appears to have too much sand and it loosens up when walked on. It also has a 2 1/2 inch pitch that has to be corrected. I'm trying to find something locally (Long Island, NY) that will correct this problem, and which is hopefully self-leveling as well. When it's completed, it will have a wooden sub-floor over it. I'd appreciate any input that you may have...
