We got hit with another 100 year rain last week in Chicago. Seems like 100 year rains come every year now. I'm looking to put a perimeter drainage system in my basement feeding into a sump pump. Looking for recommendations for the proper back fill, (Original construction back fill was ciders. Very common around here.) drain tile and what degree (inches per foot) to pitch the tiles. Also the million dollar question, any reduced dust methods of cutting the floor open? Total run would be about 50'. South wall approximately 22' to an elbow turning west approximately 20' to the sump pit. Another run to the center of the house approximately 10'. Pump pit will be along west wall center of the house with two inlets. One from the center of the house tile, the other from south and west tile. Should I perforate the sump pit as well and back fill around the pit with stone maybe wrapping the pit with fabric? I had planned on leaving the back fill material about 4" to 6" below floor grade to cement the pit in and prevent it from getting pushed out of the ground. Also what can I do to prevent the pit from getting crushed by the ground around it. Everything I see is either plastic or fiberglass. Any opinions are welcome. I don't want this job to have to be a redo! Thanks, Glenn.
