A permanent form for placing a basement concrete wall includes a percolation layer and a water-conduit channel for discharging water leakage or the like from a basement concrete wall. If the basement concrete wall is placed using the form, the percolation layer is impregnated with cement paste of concrete, whereby the form and the basement concrete wall are joined to each other. Redundant water before hardening the concrete, water leakage after hardening or the like flows into the water-conduit channel through the percolation layer, flows downward through the water-conduit channel, and is discharged from the bottom of the form. In addition, heat from the basement concrete wall is cut off by a heat insulating layer provided on the side of the interior as viewed from the water-conduit channel.
