This is what i did to stop a major groundwater issue with clay soil in my house. Was put in when i did foundation though, so it was easy. 8-10k would be paying someone to do all the work. I think ive got mine done under 5k.
Revisiting this: would you still spray the concrete in waterproofing and put the insulation board over that and then wrap the insulation board with some type of waterproof membrane?
Or not spray the waterproofing on the concrete, just install the insulation board and wrap in membrane?
Iím thinking that you donít want the insulation board sandwiched between two waterproofed items.
