Abstract:
A method of providing fluid drainage for a foundation that is cast by placing concrete between an outside-form-wall and an inside-form-wall, comprising, after the form walls are erected, the steps of:placing a drainage mat, having a face and a back, against the inside of the outside-form-wall extending along the length of the outside-form-wall; attaching the proximate end of at least one through-conduit in fluid communication with said drainage mat and extending the distal end of said through-conduit to be flush with the inside of the inside-form-wall; placing concrete between the outside-form-wall and the inside-form-wall; allowing said concrete reasonably to cure, whereby the foundation results; removing the outside-form-wall and the inside-form-wall; attaching conventional means for drainage to the exposed distal end of said at least one through-conduit; and backfilling the foundation.
