Fabric form footing and ICF foundation wall
Fabric form footings are an innovative way to cast and form concrete footings using non-woven polypropylene, woven polyethylene or other similar materials, with the fabric supplied in a bag format to form pads for columns or a continuous format to form strip footings. The fabric is laid on the ground and, when filled with concrete, conforms to the uneven ground surfaces. The fabric is left in place preventing rapid drying of the concrete and eliminating the need to strip away the formwork. When integrated into foundation forms such as ICF formwork shown in Figure 34, concrete footings and foundation walls can be cast in one continuous concrete pour.
