Abstract:
1. In a method of forming self-sustaining concrete structures from flowable concrete pours, the improvement comprising: installing a flexible barrier element on at least a first forming panel; combining the first forming panel with other panels to create a form into which flowable concrete is poured and retained as it cures; using the barrier element to reduce leakage from between the first forming panel and an adjacent panel during the formation process; removing the first forming panel from the concrete structure after curing without removing the barrier element from the first forming panel; and reusing the first forming panel to create another form, further comprising installing a flexible barrier element on at least a second forming panel and positioning said first and second forming panels adjacent one another as part of a form, further comprising using the barrier elements on the first and second forming panels to reduce leakage between the first and second forming panels during the formation process, said barrier elements on the first and second forming panels engaging one another when the first and second forming panels are positioned adjacent one another as part of a form, further comprising placing at least one tie bar between the adjacent first and second forming panels, said barrier elements on the first and second forming panels engaging opposite sides of the tie bar when the first and second forming panels are positioned adjacent one another as part of a form, said barrier elements on the first and second forming panels projecting outwardly from their respective forming panels at an oblique angle relative thereto and generally toward the concrete pour.
