Hello,
I'm fairly new to the DIY'ing, but i've recently bought a house and need some advice on a damp issue recently discovered under the front door.
I'm planning on putting down a solid wood floor, and have recently pulled up an old lino floor and scrapped up all the self leveling stuff it was laid on. However, by the front door, not only did that come up, but I found what seemed to be the concrete floor was damp and weak, and I lifted up the crumbly/damp 5mm layer over the inner line of bricks and cavity with my bare hands.
The cavity was filled with mud/sand/concrete - all damp. and there didn't seem to be any dpm between the inner line of bricks/concreted cavity and the screed that was covering them. I've pulled it all up now, dug out the cavity to about 1 brick depth, and am now unsure exactly how to proceed.
As you can see on the photo's, there's the dpm between the bricks and the concrete floor just poking up in places, and using a damp tester the concrete floor is dry. Having read other similar threads here I had hoped to create a trench of DPM into the cavity, fill with concrete, then possibly use some epoxy concrete repair or similar on top to create a hard smooth floor up to the level of the concrete.
I assume I need to join the dpm all together to get a decent seal from the dpm between inner bricks/concrete across to the dpc under the door. Thing is, I'm struggling as there's nothing to really attach to at the inner line of bricks as it appears to have been cut back, and there's only a slither of dpc poking out under the door. Would somehow using a liquid dpm be an option?
Can anyone advise on my next steps? Thanks in advance
