  • #13: Each panel is a monolithic pour using a consistent batch of 5000psi fiber reinforced concrete. A 5000psi concrete is used for strength and for watertight characteristics. The concrete mix exceeds watertight standards determined by the American Concrete Institute. Incorporated into the concrete are multiple layers of 1/2 and 5/8 steel reinforcing rods. Foundation panels weigh between 440 and 512 pounds per linear foot. Our insulated product consists of 8-1/2 of EPS foam with an R-value exceeding R-30.
