(57) A pocket isolator form, for placement around a footer before a concrete slab is poured, is formed from plural barrier sections. At least some of the sections are curved, so that a sharp re-entrant corned is not formed in the concrete slab. The curved sections may be assembled with straight sections to form barriers of various form shapes which avoid the creation of sharp re-entrant corners in the slab.
