ABSTRACT:
A method and apparatus for placing cementitious material into an excavation using a mobile unit having an extendable flexible hose mounted on a power driven hose reel. Cementitious material is pumped through the hose and out the hose end into an excavation as the flexible hose is reeled out of the excavation. A weight at the end of the hose keeps the end of the hose from jetting itself about during the pumping operations. An extendable hose boom positions the end of hose over an excavation and directs the hose into the excavation and out during pumping.
