    Question Old rock and mortar walls

    We have an old home built in 1916-1917, in the northwoods of Wisconsin. Our basement has rock and mortar(we think) walls. The walls need repair and reinforcement because some of the mortar areas are crumbling. We would also like to put walls up to finish this old basement after the initial repairs and reinforcements are completed to the rock. Can anyone recommend a product to help with repair and reinforcement?

    Do you intend to do this yourself, or hire a contractor???

    Could you post some photos of the basement.

    This usually requires pulling a permit from your town hall if you diy.

    An expedient time-saving method I've used several times is to pour a sister wall of steel-reinforced concrete right up against each stone wall.

    Plywood reinforced wood forms are made up and the pour is usually done manually; a concrete ready-mix truck will usually have too much force when pouring, and blow out the forms.

    If you have to go all the way up the height of the basement wall, removing the perimeter wood on the 1st floor to gain access will make it a lot easier to mix & pour the concrete into the forms.

    This is generally done 8' at a time with a steel-reinforced footing poured first.

    Steel rebar is installed in the forms before the pour, and extend out 2' beyond the forms so that the next subsequent pour can be tied into the first.

    The forms must be stoutly braced with 4 X 4 lumber, but 2 X 4 is often sufficient.

    A concrete basement floor is then poured, although this can also be done first.

    The nemmar site below shows some "sister wall" applications, as well as bench footings; see diagram 230 & 260; Diagram 261 illustrates an outside sister wall; in your case, it would be poured inside the basement.

    If you have trouble loading the diagrams, Google "nemmar house illustrations" (without the quotes) and load the "cached" version of the site.

    We had planned on doing the work ourselves.
    We thought that was what we were going to have to do. Was hoping for something more simple. Thanks for the information, it will be very helpful.

    Would suggest to put concrete walls in and then cover them over with Cut River Rock stone veneer. It looks like full stone and is real. Check out their website http://www.cutriverock.com
