Abstract: A method of applying a layer of filler material to an existing concrete foundation to provide a substantially level foundation surface, includes the steps of determining the amount of deviation of the top surface of a foundation wall from a level surface and the amount of filler material sufficient to minimally exceed the volume formed by the deviation along the foundation wall. The method includes positioning a filler material retaining form along the top surface of the foundation wall and securing the retaining form to the foundation. The form consists of a sheet of resilient material having a perforation in the top surface thereof. The determined amount of filler material is poured into the form through the perforation and then allowed to harden.In this manner a substantially level foundation system is provided which comprises a layer of hardened epoxy-resin material along the top surface of an existing foundation wall.
