ABSTRACT:
The present invention10discloses a concrete form system for building foundations wherein two substantially parallel form walls12are constructed using a plurality of retainer sections that can mechanically interlock end-to-end42, 44when the retainer sections14, 16, 18, 20incorporate a throughbore22or butt-up end to end when there is no throughbore. Additionally the present invention provides a separator bar and reinforcement posts whereby the separator bar24serves as base for the retainer sections and as spacer between stacked retainer sections14, 16, 18, 20which can in cross-section have a circular, oval or polygonal shape and in one additional element a ribbed exterior portion46, 48for added strength and a substantially hollow interior22that forms a corrugated conduit retainer20that is conducive to providing ventilation for effective and efficient radon remediation from the structure being constructed. The aforementioned corrugated retainer20uses a combination of straps50and spreaders40to maintain the two form retainer wall12in place prior to and during the pouring of the concrete36.
