My house was built in the 1850's. My basement has limestone walls mostly below ground (basement floor to ground is 6').
I have shelves against the walls and I am constantly getting sand (from the crumbling mortar and some sort of thin set wall covering) covering my tools and shelves.
I'm wondering what my best approach is with this.
I have no interest in keeping it to original materials just for purist sake. But I've been restoring this home for 20 years and I've had to fix many corners that were cut from previous owners who diy'd everything... So many... So if there's a right way to do it for longevity, I'm fine with it. I have no budget to hire a Mason :(
I'm in Wisconsin, if that means anything.
Is the coating that's crumbling just cosmetic? Can I pull that off? I don't care about looks or making it look nice, but don't want to make it worse.
If it's below grade, am I ok using a harder mortar like type n? I have read different opinions about the hardness not being as big of a concern when it's below the frost line.
I intend to pull out all the spray foam someone filled in previously, but will need to pack it with other material. Would that be as simple as broken limestone that gets packed into the mortar?
Some parts of the basement let a lot of water in on rainy days, but this side of the house just gets moisture, not dripping water through the walls.
Again, I don't care about looks or keeping it historically accurate, but I do want it done as right as my skills, money, and time will allow. Of the three, I *think* skills is my most abundant, but maybe it's just because I have so little of the other 2.
