An adjustable mold for manufacturing a pre-cast retaining wall, said adjustable mold comprising:
- a platform having a substantially horizontal orientation, said platform defining a top surface, a first side, a second side substantially parallel to said first side, a first end, and a second end, said top surface defining a mold negative shape of a texture for an external surface of the pre-cast retaining wall;
- a first side rail and a second side rail operatively connected to said platform proximate to and substantially parallel to opposing sides, said first side rail and said second side rail extending upwardly from said top surface;
- a header rail operatively connected to and spanning between said first rail and said second rail at a selected distance from said platform second end;
- said first rail, said second rail, and said header rail cooperating to define a first cavity;
- a upright form wall spaced apart from said platform first end and oriented substantially orthogonal to said platform top surface, said upright form wall defining an upper portion extending above said platform top surface and a lower portion extending below said platform top surface;
- a channel member defining a channel between said upright form wall and said platform first end, said channel opening upward and extending downward from said platform top surface;
- a first channel side member and a second channel side member operatively connectable to opposing sides of said channel member, respectively;
- said channel member, said first channel side member, and said second channel side member cooperating to define a second cavity in fluid communication with said first cavity;
- a central bulkhead member spaced apart from said upright form wall, located proximate to and upward from said platform first end, and oriented substantially orthogonal to said platform top surface;
- a first bulkhead side member and a second bulkhead side member operatively and selectively connected to opposing sides of said central bulkhead member and opposing sides of said upright form wall upper portion, said central bulkhead member, said first bulkhead side member, and said second bulkhead side member cooperating to define a bulkhead, wherein at least one of said first bulkhead side member and said second bulkhead side member pivotally connected to said upright form wall along a vertical axis;
- and
- said bulkhead and said upright form wall upper portion cooperating to define a third cavity in fluid communication with said first cavity and said second cavity.
