The present invention 10 discloses a concrete form system for building foundations wherein two substantially parallel form walls 12 are constructed using a plurality of retainer sections that can mechanically interlock end-to-end 42, 44 when the retainer sections 14, 16, 18, 20 incorporate a throughbore 22 or butt-up end to end when there is no throughbore. Additionally the present invention provides a separator bar and reinforcement posts whereby the separator bar 24 serves as base for the retainer sections and as spacer between stacked retainer sections 14, 16, 18, 20 which can in cross-section have a circular, oval or polygonal shape and in one additional element a ribbed exterior portion 46, 48 for added strength and a substantially hollow interior 22 that forms a corrugated conduit retainer 20 that is conducive to providing ventilation for effective and efficient radon remediation from the structure being constructed. The aforementioned corrugated retainer 20 uses a combination of straps 50 and spreaders 40 to maintain the two form retainer wall 12 in place prior to and during the pouring of the concrete 36.
A concrete form system which provides an integral venting system for removing unwanted gases from the foundation footing of a building, said system comprising:
