ABSTRACT:
The method of making a replacement flooring for a dump truck having a body upon a frame, the body including front and side walls and a damaged, punctured flooring plate, comprising the steps of superimposing a metal replacement floor over the damaged flooring plate, peripherally welding it thereto defining a sealed chamber between the plates. Further steps include drilling a vent and fill opening through the replacement plate, thereafter injecting under pressure a two-stage thermosetting copolymer filling the chamber and thereafter curing the copolymer providing a hardened spacer filler between the plates. Replacement flooring for the damaged flooring plate comprises a replacement floor plate superimposed over the flooring plate and peripherally welded and sealed thereto defining a sealed chamber between the plates. A hardened cured filler spacer of a thermosetting copolymer material is snugly interposed between the plates.
