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.
