Abstract
The present invention is directed to a method for preparing or repairing a machine foundation by using a hollow form which surrounds vertically extending reinforcement rods and is filled with a fortifying material to secure the hollow form to a slab. The form is preferably made of an aggregate filled thermosetting resin or a thermoplastic resin which are corrosion and chemical resistant materials free from fluid attack such as the liquids in the machine, for example, in a pump the fluids being either the lubricating fluids or the fluids being pumped. More particularly, the present invention is directed to a hollow form which may be used either to prepare a machine foundation or to repair a degraded slab or foundation and preferably is a single form.
