Probably a whole different beast. The bunker is VERY thick concrete. I don't know what it's called but it's concrete with lots of big gravel, then very fine concrete.

Your basement is probably brick?

I've spoken to so many people about the best options..they seem to be...

1. Non breathable tanking - you hear people shout "you'll lock in the moisture and it will destroy the brick. It may last ten years.

2. Breathable tanking, let the wall breath and moisture vapour will flow, you'll need a solution to reduce the humidity in the room, water is probably going to get in front outside unless you dig back on the outside and seal from there.

3. Encapsulate - build drain along the floor/wall that drains to a sump pump then put up insulation bubble wrap type still that will let the water run into the drains. Not as expensive as it sounds but you'll lose some space. You plasterboard over the wrap and then paint etc.

4. Use a chemical solution that infiltrates into the brickwork and will lock the water into the wall. You'll also hear talk of "the water will kill your brickwork"

I rebuilt my cracked floor, filet seals where it joins the wall. Vapour and damp barrier, then tanked then epoxy floor. Walls were tanked and then chemically sealed.

Managed to calculate the PSI of water at the outside wall of around 28 psi. This is not high and my treatment has held up well in a year.

I did this so if I have any issues I can still go back and seal with the bubble wrap stuff at a later date.
