There is a section of the foundation--about 6' long--that looked as :sleep: was covered with a stucco type cement. It is different from the rest of the foundation (poured cement in a brick pattern mold). It is along the garage wall/laundry room section of the house that is on a cement slab. House was nearly 17 years old when we bought it. After a few years, the cement stuff peeled off, revealing nothing but styrofoam under it. Well, that seemed sort of weird, but mixed up a batch of cement and slapped that over the exposed styrofoam, and it held for a few years, but is again coming off. What did the builder not do that he should have done, and what do I do to correct this problem? Slopping cement over this 3 x 6' section is just a temporary fix.
