A Connecticut company has introduced
a polystyrene foundation form system
that includes a footing block. Poly Form
footing blocks are 24 inches wide, 12
inches high, and 48 inches long; corner
blocks are 24 inches long on a side. The
footing blocks are shipped in two halves
— an inside section and an outside section
— that are joined together during
installation using foam separators that
slide into grooves on the inside of the
blocks. The precut miters on corner
blocks can be glued or taped at the corner
to form a 90° angle (gluing does the
best job). When used with the company's
foam wall forms, the result is a solid, noseam
foundation wall that
