crumbling mortar in basement

Posted by ku9296 (My Page) on

Hi there, we moved into a very old house (built around 1910) a couple of years ago and with all the heavy rain a few days ago noticed a leak in the basement. There was a small hole in the wall/floor joint area so we patched it up with hydraulic cement. Upon working on this, we noticed that the mortar between the bricks and stones in the basement wall are crumbling, probably due to moisture.
Should we take out all the crumbly mortar and put in new mortar (or should we use hydraulic cement)? Should we also Dry Loc the wall after all the mortar is re-done?
Any advice would be greatly appreciated!

RE: crumbling mortar in basement

This could be a serious structural problem that won't be fixed by patching and it would be wise to have a structural engineer (or at least a specialist who doesn't have a financial interest in the outcome) look at this now. If you patch now and it doesn't resolve the problem, more damage could occur that would make the situation more serious and more expensive to fix. Maybe it will be a fairly easy fix; but, if it's not, now -- not later -- is the time to find out. In an extreme case, a deteriorating foundation wall can result in a house settling, things getting out of plumb, cracks in walls, etc. Better to prevent than fix...

Many thanks for the advice--I think we'll have someone come in and take a look at the basement. Certainly would like to avoid an exacerbated situation! Thanks.
