- a brake lever located on said pipe,
- a brake housing attachable to said grout pipe second end,
- a cavity within said brake housing through which grout may travel from said pipe,
- a control box, said control box being pivotable with respect to said brake housing,
- a brake cable between said brake lever and said brake housing installed such that actuation of said brake lever locks the position of said control box with respect to said brake housing,
- at least one hose for transporting grout from said brake housing to said control box,
- a cavity within said control box for receiving grout,
- a control block attached to said control box,
- a valve located within said control box cavity,
- at least one grout inlet port located in said control box cavity, said inlet port being located so that movement of said valve can close or open said inlet port to grout flow,
