I bought a fixer upper house that has some wet basement issues. Stone foundation, leaks in walls and basement cement floor, no sump pump.
We have a very high watertable in the area.
Looks like previous owner cut a drainpipe in and started to cut a french drain but I don't know where it goes and it appears to be clogged. Should I unclog and reuse in some manner or seal it?
This is my plan.
1. Clear exterior bushes against house.
2. Regrade exterior (I don't have much room to work with so no exterior trench drain). Should I try a "drain mat" under the regraded area? I wish I could dig a trench around the outside and mortar the stone on the exterior of the foundation, add waterproofing, etc..but many say that will compromise the integrity of the stone foundation.
3. Then, what is my next step? The covering over the stone foundation is crumbling throughout the basement. I was thinking about brushing all that off and adding new layer of mortar to better seal the stones. Any advice on this?
4. Once I do that cut a french drain and install sump.
Should I put a vapor barrier up somewhere? What should I do to improve the cosmetic appearance of the visable stone after resealing stones? Throw a layer of cement over it? I don't mind bringing in a contractor for parts of this if it can get me a finishable basement, but I am not paying one of these sham "basement waterproofers" that want $10000-$30000 for work that is 95% labor.
Please tell me anything that I can do to improve the situation myself without hiring a contractor. I'll take any exterior advice you can give too, but again, I do not have a lot of space to work with.
I plan to keep this house a long time, so long term fixes only.
