Repairing bowed foundation
1/17/2021 at 7:35:51 PM
I am looking at Purchasing a 1400sq foot home with a cinderblock basement. the basement walls have all bowed .5-1.5" I am wondering what the repair options are for this.
I have been quoted for geo lock anchors every 6' or power braces every 6' the quote was quite expensive and I am wondering what other acceptable methods for stabilizing the wall there are? I understand some landscaping will be needed to stop the problem from recurring as well and am only interested in the cost/options to reinforce the walls as landscaping will be done DIY. I have heard that a new poured cement foundation wall can be put inside of the existing block foundation, or a new wood foundation can be built. I am not sure if these are considered long term repairs or the cost of them though.
This is a finished basement, so the least intrusive the better and refinishing costs would need to be calculated into the cost as well. However refinishing is something we could do on our own and would likely have the materials.

Hi,
I'm not an expert in foundation repair but has anyone suggested digging small sections on the outside of the foundation to re-set the blocks one small part at a time? Similar to how you'd waterproof the outside of a basement or when you're repointing the mortar on an old stone foundation? I'm not sure if this would work if the whole wall had shifted, but if you're looking at landscaping anyways I wonder if the basement has a waterproof membrane and if you excavated a small trench and supported the house, could the block be re-set? Again, I'm no expert - just an idea.

I am registered engineer and president of NOAR Professional Inc. with extensive experience in structures and Foundations.
For making a better decision we should have more information such as height of wall, type of soil, water table level and if there is any surcharge load, also wall situation right now.
Putting some anchors is one option and new wall seems better chose if it possible.
Anyway, it is unsafe and shall be make a proper action as soon as possible. An engineer needs to find out best choice by doing some calculations regarding to subjected loads.

Not sure where you are situated. We do this type if work all the time. We have a bracket that bolt to the floor and straightens wall via a 4"x4" square tubing and if it is realy bad we poor sections of wall and fill webs in blocks as well. With pictures I can guide you to the right fix.
