New Home Problems!
1. A base of 4” of #57 or #67 washed stone should be placed over a compacted sub-grade.
2. A 6-mil polyethylene vapor barrier should be placed over the stone and all holes and seams should be taped or sealed.
3. Welded wire fabric (reinforcement wire) should be placed with a 6” minimum overlap at all seams.
4. The concrete should be 4” thick and poured at a 4” maximum slump, pulling the reinforcement wire up into the concrete as it is placed.
5. After the concrete is finished it should be protected with a moisture retaining cover, or chemical curing compound to maintain as much moisture as possible for a minimum of 14 days.
Not following the procedure above will result in excessive cracking. The superior walls should not have a cracking problem either. I would also suggest you contact Superior Walls and tell them about your problem. If the builder did not follow all the manufacturers recommended procedures during the installation he should be liable for these repairs. If he did follow all the proper procedures Superior Walls should make the repairs under their warrantee.
I am very interested in knowing who installed your precast walls. Were the problems resolved to your satisfaction?
There's no mention of warranty details on http://www.superiorwalls.com.
We called the main office in PA and we were informed they have NO responsibility for the warranty....is up to the franchisee. After initial contact a Mr. Hawthorne was unresponsive to several phone calls.
I've also contacted Bob Villa via this web site and got no reply. I'd like to think that if Bob were aware of the warranty details, he might not be so embracing of the Superior Walls foundation.
I'm not looking to sue anyone, I just want a dry basement and thus far this is not the case. I will update this thread if anything changes.
I think Bob Villa should get involved and stop recommending this product by virtue of their advertising.
Our basement floor has numerous fissure cracks that are widening.
