Would appreciate advice,I'm pricing a job for a basement.Its a very old house with a stone foundation,due to age and moisture all the cement grouting is falling out and the customer would like it all sealed up and just a textured finish,I was wondering if there is a product out there that I could use to fill in all the stones before overlaying the surface.There's some huge gaps and holes to be filled to bring the wall even,or should I just fill it in with a portland/sand mix.The basements a little over 800 sq ft.
This is tricky but here is my experience...
If you can not get to the out side of the housed and tar, seal , protect the moisture from leaching in what ever you put on the wall is subject to failure…..
Old walls like that let a lot of moisture in, the problem is not with the mix its with the moisture coming behind it and delaminating the products right off the wall.
If you clean and re grout the stone work and then seal it you have a chance… you can also try epoxy based grout…and basically tuck point all the stone work… thats probably not gonna fly but I can tell you this… to just clean it up and shoot it with a plater coat and a sealer … you will face some issues at some time...
You may want to build a wall with a moisture barrier all together…. may be faster and offer a better environment.
Dank moist basements are really go for mold as well … de humidifiers and plenty of air circulation behind the wall will keep that at bay.
thanks for the info guys,Nate building a new wall is not an option,they just want it sealed up and their looking at $12-$14k to do so.I'll try a bonding agent on the stones and then filling it all in with Portland and then quikwall to finish it and then a sealer, that's even if I get the job.maybe in the spring they'll let me stoneface the outside foundation,that should do it.But this is Rhode Island people don't like spending $$$ we'll see,again thanks for the advice
Thanks again guys,The outside should b sealed too but they want to focus on the inside now.Its more damp and coldness in the basement that they want fixed,anyway I gave him a price for the whole job or doing it in sections and he has to talk it over with his wife and get back to me,that usually means no, this is rhode island unless you work cheap you don't work much.Its hard to find people that want nice work done right.I HAD a job to overlay and stonefinish a set of brick steps that all the joints were falling apart and cracking but lost it yesterday to a mason who's just gonna repoint it.Its cheaper!Thats life here.Anyways you guys are really great to offer your advice to help out thanks again.I'll post how this one goes
Scott which Xypex product did you use for your pond. Was it a cementious 1 that you could brush or trowel on?
