Hi all!
Love the forum - first time posting.
Over the past few months I’ve been ripping out a VERY damp basement that had partition walls made of plasterboard (NOT moisture resistant), and a fairly large ingress of water from an old service opening that had been left ajar for about ten years!!! (All this was found when ripping out - missed it when purchasing property - ooops)
Anyway - putting these together, created an astoundingly wet and damp environment that affected the flat above terribly. (Basement is about 7x7 meters under footprint of house)
Since removing everything the basement feels a lot better, and I’ll be installing some mechanical ventilation soon to help airflow and moisture levels.
I want to get the area good enough to use as a den / garage - just storage really - but to avoid damaging items down there, and getting it to a level where everything doesn’t have to be in boxes.
The floor seems to be pretty damp, and there is still slight ingress of water in heavy rain from the old service door (is now a manhole set in to a slab that lets water through in rain)
My thoughts are after airflow improvements, to membrane the floor to slow the vapour coming from it (don’t have enough money to dig it up and relay with DPM etc), and lap it up the edges - let’s it breath and hopefully the airflow will take care of it before it builds too much.
And also I want to seal up the manhole area as much as poss to make it water tight - but unsure on approach - maybe just tanking slurry from inside on it?
I’ve never tackled a basement before, and wondered thoughts on if I’m approaching the right, or wrong way!
Thoughts welcome - and have attached some images as it stands!!!

area is the spot with the manhole that leaks just after some heavy rain all day today)
