Is it feasible to do a concrete floor (ie 6 inches), concrete footing for wall, cinder block wall w/ mortar joints, and seal the concrete/blocks for a pool in a cold harsh winter climate? 6-8 foot deep end would be great, looking at 20'x40' rectangle but will probably end up smaller.
Not sure if footer can be separate from floor or should be one pour.
Want to do ready mix delivery for the floor, blocks myself, and worry about the plumbing and electrical after. Or is this a terrible idea?
