- Historic old homes constructed of rock and lime based mortar are deterioration at an alarming rate, crumbling mortar, shifting rocks are some of the signs of a fieldstone foundation in need of repair. Over time water and moisture will break down and wash out the lime in the mortar leaving piles of sand around the perimeter of your basement.
This is mainly cased due to the fact the exterior of the fieldstone foundation; below the grade of land there is no mortar. All the mortar that supports your old stone foundation is packed from inside the basement and also on the exterior, above the grade of land.
Homeowners that are doing landscape project around the house, digging against the foundation or removal of shrubs and bushes will often notice when its raining the will experience water in the basement. Disturbing the soil around the fieldstone foundation will uncover the below grade part of the stone foundation exposing the open stones and allowing water to enter. The most important thing to remember is disturbing the soil against a fieldstone foundation could cause structural problems.
Look around at other homes and there fieldstone foundations you may notice that parts of the stone foundation are actually block wall or poured concrete. These are structural repairs, which cost the owner tens of thousands to do. Foundation failure? Once the large stones within the foundation fall into the basement or bowing of the foundation starts, its impossible to break it down and rebuild the stonewall in the basement. You now have to hire a structural engineer, a foundation installation company to structurally support your home. This is why it is most important to fix the crumbling mortar, by method of re-pointing, and add a white wash coating, by a professional contractor with experience in fieldstone foundation repair. Your home is as stable as the foundation it sits upon. Don't just let anyone work on your foundation
On some fieldstone foundations’ you’ll notice a white coating or plaster type of material on the stone walls in your basement, this is a method of waterproofing a fieldstone foundation called white washing or lime washing. This slurry coating not only brighten up the basement but also preserves the mortar allowing the fieldstone foundation to last even longer. Many masons, historians and foundation repair companies go back and forth about white washing, some claim it does more harm than good others disagree.
In my experience in restoring fieldstone foundations basements that have had white washing applied to their foundation tend to need much less work to them. Proving that white washing is very beneficial to fieldstone foundations and saving homeowners money.
Fixing a fieldstone foundation takes experience, this is by far a do it your self type of project knowing the basic skills of repointing a stone foundation is only one ingredient to the restoration or repair of a fieldstone foundation. Most times homeowners will run out to local hardware store and pick up hydraulic cement as an attempt of repair. Or even spray foam as part of sealing out drafts in the foundation or hire a company to just do some quick patchwork. These are the most common type of repair you’ll notice in a fieldstone foundation and almost every fieldstone foundation has some degree of problems.check us out at www.stonefoundationrepair.com

I like what I see, a job well done..... I did this kind of work for some years and we always made sure to finish all walls top to bottom with a finish base line...This is a well done job, clean and neat to the finish...To bad I now need this done to my basement where it might be some what of a bigger job for me to do...Nonetheless I will try to do a test wall to see how it goes.. Wish me luck, thanks for the video...JRC
Type S mortar is the best to use around fieldstone. It’s two parts Portland and strong with hydrated lime. All masonry contains lime, choosing the proper mortar is key
very well done....
If small 3 or 4 foot sections are dug straight down on the outside and sealed and filled with concrete would that work? I understand the idea of the outside dirt pressing against the foundation holding foundation in place so would small sections of sealing and concrete reinforce the foundation and prevent water seepage?
Is it a good idea to pressure wash the interior of the fieldstone basement? I have a fieldstone basement, and are looking for people to do re-pointing work. Does your company have other ways to prepare the surface, because I am not comfortable with pressure washing? Thanks.
my basement looks exactly like this and after lot of research I am going to repoint with lime mortar.Previous owners already did some damage with portland cement but I'll try to work around it.
Do you ever dig down to the bottom (not below) of the foundation on the exterior and do a parge coat and then add some kind of membrane that leads to a french drain to divert water?
Waterproofing should be done on the foundation exterior. Doing it on the interior without the exterior will cause water saturation and damage the stones. Also ideally you would use a lime/sand mortar (no cement) but a cement-based type N mortar would be OK too (it's soft enough to allow the rocks to shift naturally without crushing them). A lime/sand mortar wicks moisture and protects the stone the best but is weak and may need more frequent replacing.
done right my arse! never use cement on stone walls, it's rule number 1!
I like what you did here but you mentioned that waterproofing should be done from the inside and not the outside. What if water is pooling at the bottom of your foundation? Not as a result of a downspout but because your home is on lower ground. Wouldn’t something like a french drain be applicable then?
looks good.
Does the waterproof coating come in other colors? Maybe a more natural stone gray? Is there such thing as a clear coat to preserve the look of the natural stone underneath? Thank you!
3 and half sharpe sand with 1 dry-mixed natural hydraulic lime. Pack with small pebbles stone's.
I have that stuff in my basement. It falls off in little powdery chunks and has to be swept/vacuumed frequently. You're better off leaving the waterproofing off and letting the basement dry out occasionally. This waterproofing will just give you soaking wet walls all year round. I don't buy that this is a good idea, I'd do a lot of research on your own before you seal your basement on the sayso of one private company owner.
is it possible to give me a rough estimate of a 24 ft x 50 ft foundation repair with adding a cement floor over a dirt floor? I am considering buying a home that needs this and want to know how much it might cost.
I would be pissed if I was the home owner. Distroyed the rock wall look. How about outside correcting the real problem?
You can not use mortar that is harder than the stone you are using, that is a basic rule of masonry. Limestone can not stand up to modern cement. The stones will crack, and all you will have left is the mortar.
I thought it best to use a 3.5 hydraulic lime based render instead of cement render to allow the stone wall to breath (water vapour in and water vapour out, a natural process ??). Why seal the stone wall using cement ? Should we not use lime based mortar ?
Shouldn't they be using a lime based mortar with a stone foundation instead of cement based mortar? Would cement cause the stone to degrade over time?
I want to purchase a 1940 home with fieldstone foundation (basement) there is a huge rock and I was wondering if I should just keep searching for homes or purchase and fix it myself.
