Fixing improperly cured concrete

froggy · Feb 13, 2004

We have a fifty year home that we purchased many years ago that has an add-on closet to the back bedroom. We knew that the addition was not great workmanship, but purchased the home anyway.

The question I have, is there anyway to fix the foundation under the closet? It looks like the concrete was improperly cured. It looks like compressed sand and breaks off very easy. I know that we are going to have to fix it before we sell and move to our retirement land in Cooke County.

Does anyone have any suggestions? Will it have to be ripped out completely or what? /forums/images/graemlins/confused.gif

Thanks,

With out knowing the details of the construction it is hard to say. Is there enough room to form and pour a new foundation using the old foundation as one side of the form. You say it is just for a closet. That shouldn't require much of a foundation. Would 4 corner posts work, with a wood or metal beam between them to carry the structure.
There are some materials (epoxies I believe) that can be injected in concrete that is crumbling to esentially turn it into a block of epoxy. I think once you price this it will be cheaper to just remove and replace the entire structure.

Thanks for your input. Guess the best thing is to just remove the old foundation and put in a new one.

Look at the bright side. If it's as sorry as you say then taking it out won't be as hard as it could be. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif
