I need help! I live in Calgary Alberta, Canada. Our city was recently hit with a massive flood. Thousands of homes have been affected by this flood. My own house did not have overland flooding but did end up with 3 feet of water in the basement. The water entered the house through drain cut outs in the concrete floor. Unfortunately my house did not have a sump pump. The entire basement has been gutted with new water heater and furnace. I contacted a company about installing sump pumps. They have also suggested a system with internal "French drains" for around the perimeter of the basement. This would involve removing a 10 inch or so amount of the floor and part of the footing to mitigate water coming through the joint between the footing and the wall. My question is this a good idea? Are sump pumps enough? Will removing the concrete to put in the drain effect the footings so I later will have a problem there? During this flood I had no water coming in at the joint just through the cut outs in the floor. Can anyone give some advice? It will cost about 22K for the drain and sump pumps.
