Insulated Wall In The Basement

Did some work on the basement walls on my day off today. Over the last few weeks I discovered the previous owners created their "finished" basement with the wrong techniques for finishing the walls. They buried electric, insulated the walls incorrectly, nailed wood into the foundation walls which put massive holes and finally, a water line. A hot water line was run behind the insulation against the cold foundation wall. This has created condensation and a small amount of mold (smelled nasty).

I have taken everything off the walls (drywall, insulation and one by twos). I then used Drylok to seal the wall for water. Today I removed the water line by installing a Shark valve. This allowed me to shut off the water flow I that direction and the option to add a Pecs water line later.

Next Ryan and I used foam board adhesive to glue foam board on the walls. The foam board has a R value of 4 which is nothing but it will give the wall some moisture protection.

The last thing we did was install metal 2 x 4s. I used an actuated gun to shoot nails and secure the metal to the basement concrete. I've never done this and was very nervous to use the tool. It worked out ok meaning I didn't get my hand or other body parts shot.
