Will Fastfoot affect the lateral resistance of the footing with the ground?
As most footings are designed to transfer vertical loads from the building structure to the ground below, the fabric will have no effect on structural performance. Significant lateral resistance is provided by footings as a result of the following: the ground is uneven, and/or there is a slab or floor inside the foundation Under these conditions, the footing (either fabric or lumber formed) can withstand normal lateral loading. If the footing is constructed on very flat ground and there is no slab to prevent lateral movement (for example with retaining walls), the footing must be engineered to withstand lateral loads. In this situation an Engineer must design the proposed footing. The angle of interface friction of the Fastfoot fabric sliding on itself is 32 degrees from the horizontal.

Standard engineering practice is to ‘key’ the footing into the ground by digging a small keyway parallel and under the footing before placing the fabric and pouring the
