| | Form-A-Drain system by CertainTeed is a patented 3-in-1 foundation solution that forms footings, provides an integrated drainage system, and can be easily adapted to vent radon where needed. Designed for residential basement applications, Form-A-Drain consists of lineal sections installed as the foundation footing forms. Unlike standard wood forms, Form-A-Drain lineals stay in place permanently after completion of the concrete pour, enabling them to function as a foundation drainage system and because they form a complete sub-slab perimeter loop around the foundation a key element of a radon reduction system. And because it stays in place, Form-A-Drain shaves valuable time from the construction schedule; there's no need to return the next day to remove, strip, clean and transport forms to the next jobsite.
This specification includes Form-A-Drain system that functions as: Formwork for footings. Foundation drainage system. Radon gas evacuation system.
The Form-A-Drain system conforms to "Model Standards and Techniques for Control of Radon in New Residential Buildings" - Environmental Protection Agency (EPA), and is the subject of BOCA Research Report Number 95-37, dated 1995 and renewed annually.
