Footer Form/Drain Combo The Snap Forms combination footer form and foundation drain system uses modified plastic drain pipe placed in trenches in two parallel rows. Reusable rebar stakes and adjustable clamps hold the pipe in position, and the inner and outer perimeter drains are connected with crossover pipes. The trench is then backfilled with gravel to retain the concrete. Rebar hooks are available for hanging reinforcement, and the tops of the pipes act as a screed. The cost is about $1.10 per linear foot of wall. Contact: Snap Footing Systems, P.O. Box 1810, Fairview Heights, IL 62208; 800/334-4460.
