spalling concrete.


I have a retaining wall that is spalling that I want to fix. I have been told that once this situation starts, it gets worse pretty quickly. What can I use to fix this? Is it very hard to work with, or can a first timer make it look pretty even?.

That is some ugly, very poor and older concrete that is falling apart quickly now. It should be replaced with something appropriate, or if you are selling, patch it, make it look good and move quickly.

That's well beyond spalling, that's typically what we would call "rotten" concrete. Any patch over rotten concrete will likely fail within a year or so.

The problem is there is no way to add structural integrity to that wall with any kind of overlay and your wall is failing structurally.

You can absolutely do it yourself. This is a DIY forum after all. What is behind the wall/on top of the dirt behind the wall?

I will take more pictures, but there is about a 3 feet of garden (which we don't care to keep if it means its easier), and then it butts up against the foundation of the home.

That is trickier. The force that the house exerts on the ground around it extends from the foundation at a 45 degree angle into the earth around it. Would that angle of force cut through the failing wall in your case?

Well, since the wall is supporting the dirt that is supporting your house, you may need to underpin the house before removing the wall. Can you build a new wall in front of the old one in that strip of grass at the base?

Is the wall lower than the footing of the house? It is only holding up the house if it lower than the footing. If it is just holding up dirt against the upper foundation no need to worry about the house.

See Below: The Wall almost goes to the bottom of the foundation, but not quite, because the sidewalk is on a hill going down. I have a basement garage, so use that as a frame reference for the bottom of the foundation.

Oh if you have a basement then you are good to go! That wall is only supporting the dirt behind it. Have you ever done any concrete before?

Looks to me like you could even just remove it and landscape the area.
