Dimple mat down the inside of basement walls?
Hello, long time follower, first time caller.
I’ve got a block basement that was previously finished (really poorly) and due to some “events” is no longer finished. The basement has had drain tile installed internally but the walls occasionally have some minor seepage, and where the block meets the slab has some seepage. No other water pushing up holes in the slab so it seems to be draining OK not at the walls (unless I’m not understanding). We aren’t interested in re-finishing the basement but we do want to get it to the point where it can be finished. I am unable to excavate outside and dimple mat the walls and put in an external drain setup like I would like to (for a few reasons) so I’ve hatched a plan to run dimple mat down the inside walls, break the floor where it meets the wall and run the mat into the gravel for the drains, then concrete up to the mat on the floor.
Basically, capture any water coming in the walls and drain it down into the existing drain system.
Good idea, bad idea? Other ideas on how to handle it? All input welcome.
