Foundation Stucco

[obullfish]

Does anyone here know about or do stucco work? In the past few months the stucco that was put on my cinder block foundation has started coming off in large chunks. Upon inspection the areas that are coming off were coated with tar or whatever is used for water proofing when the house was built. No screen or chicken wire was used behind it evidently. Area affected is about 20” tall and about 60’ long. It looks like cement was just smeared and textured with a trowel.

is this just on the block of the whole house? How old is it?

Wire probably wasn’t used because you are likely looking at parging in lieu of stucco. It’s pretty easy to apply parging on block to make some repairs.

Just on the foundation block not the entire house. I was under the impression that if you are going to cover block work that has been coated with water proofing lathe is needed. Looks like there was no adhesion due to this coating as the areas where the coating was used are the only sections coming off. The house is 11 years old.

Something isn’t installed correctly. Parging is installed directly to brick, blocke, concrete without lathe as it’s cement based. As you can see it will not last long if installed over top of a waterproof coating.

Stucco is going to need some lathe to adhere to. Without seeing what you have it’s hard to know if you have stucco or lathe.

How far off of the ground is the waterproofing installed? Could you just patch what you have and let it be for another 11 years? Otherwise your stuck with addin lathe and applying stucco to fix. Or, depending on how high the waterproofing is and your existing grade, etc. removing the waterproofing and adding parging directly to the block.

Parging will add some level of waterproofing but I wouldn’t expect it to replace a sprayed on waterproofing coating. I don’t know the code well enough to know how high waterproofing had to be on block before you no longer need it.

Sounds like somebody got a little froggy with the pressure washer

Nope. IIRC I discovered it in early spring after we had a hellacious rain then followed by a hard freeze. To me it looks like due to the waterproofing material combined with the moisture and freeze caused some of it to let go.

Any ideas after the pictures?

I’d add some wire and do it right.

So let’s see if I got the process correct.
1. Attach lathe to block
2. Apply scratch coat
3. Apply texture coat on top of scratch coat
