Danny Epp and his two sons, Ryan and Brandon, recently formed and poured the footings for their new home in Tsawwassen, B.C., Canada, using the Fastfoot forming membrane. The building site was excavated on two separate levels to minimize excavation costs on a steep slope. The plan was to build the walls using Logix insulated concrete forms, which are 16 inches high and 4 feet long. The different levels of the footing have a 48-inch-height difference, which accommodates three levels of ICF blocks.
The engineer called for a footing 30 inches wide and 10 inches deep. Stakes were driven in the ground around the perimeter of the footing and then screwed to the screed board at the footing height. The fabric formwork membrane was pulled between the screed boards and stapled in position using width adjustment lines on the fabric.
The Epps nailed in 1×4 cleats spanning the screed boards to withstand the lateral concrete pressure and the hang steel reinforcing. The engineer required three horizontal bars with vertical dowels at 24 inches on center. The support for the dowels was raised with a 1½-inch spacer block to provide space for screeding. The fabric formwork provided the level footing essential with ICF wall forms.
Father and sons also formed the steps for the elevation change with fabric. They used vertical stakes to form the front edge of each step and attached screed boards at the top of each step. The framework was then lined with the form fabric to form and contain the concrete. They screwed plywood bulkheads to the vertical stakes to form the vertical face of each step.
The stay-in-place Fastfoot forming membrane also serves to prevent rising damp for the life of the building, providing a dry and healthy environment. For more information go to www.fab-form.com or call 888-303-3278.
