ABSTRACT:
A trench box panel with an especially lightweight foamed filler located between the inner and outer panel surfaces in a trench box panel and between structural, vertical and horizontal elements in prevention of the intrusion of water, mud and grime. The impermeable panels thus produced are more convenient to use, require less inspection in production against leakage and do not become so heavy as to be almost impossible to move and maneuver during usage. The procedures of filling the panels with lightweight unfilled foam is by use of blocks, foaming in situ, and fill foaming.
