We have a dug well behind our cottage, and are going to tear down and rebuild a new home, this time with a basement, instead of a crawl space. Right now the well is 6 feet from the cottage foundation, which is only at best 2 courses of concrete block built on sand. Old school cottage style. Funny thing is, even though it's well above the frost line (we're on Georgian Bay ), it's never heaved or cracked. My handy man neighbour says it's because it's built on sand. The sand wicks the water away, so it can't freeze and do damage. Does this make sense.?
How close to the well can we pour footings? I know we want unexcavated soil, and obviously the well was "dug". The well is 4 feet diameter, and is made of pre cast concrete sections, and is aout 15 feet deep. The water table is just below where we would need to pour footings, to enable us to have a 7 foot basment. Any advice?
I would get the advice of a Soil Engineer before you start digging. If the soil has a heavy sand component, it won't be too stable. Guessing at the proper distance could easily cause issues with the well. Or you could just drill a new well and put the house where you want.
