A solidification apparatus in the form of a rack and prongs rake structure, the prongs of which are a multiplicity of hollow tubes, each tube containing a serrated augar for providing augar assisted feeding of a gaseous suspension of cementing solids through the hollow tubes into the liquid, the rack supporting each hollow tube tine being pivotally attached to the arm of a backhoe so that the backhoe operator can generate lateral, pivotal and longitudinal movement of the tubes in the liquid while the gaseous suspension is being added to the liquid, a guard ring being provided at the open end of each tube for preventing submersion of the tube ends into the bed underlying the liquid of the encatchment.
