Abstract
A shield system for a hydrodemolition apparatus has a loop whose ends are secured to opposite sides of a reciprocating nozzle carrier. The loop may be supported by a supporting structure surrounding the frame along which the nozzle carrier reciprocates. The loop overlays portions of one or more gaps through which one or more nozzles extend to work an underlying surface. The nozzles have access to the underlying surface through the gaps under the nozzle carrier, but the balance of the gaps are covered by the loop which is drawn or pushed by the nozzle carrier during reciprocation.
