An extruded containment barrier panel (5) for use in forming a containment barrier wall about a waste material storage or disposal site is disclosed. The containment barrier panel has an elongate body panel (10) with a top end (11), a spaced bottom end (12), and a first side edge (14) and a spaced parallel second side edge (15) extending from the top end to the bottom end of the body panel. A C-shaped female connecting member (17) is formed along the first side edge of the body panel, and a complimentary male connecting member (22) is formed along the second side edge of the body panel, both of which extend the length of the body panel. The male connecting member is sized and shaped to be slidably received within a second one of the female connecting members for forming an interlocked edge-standing relationship with a second one of the barrier panels, and both of the male and female connecting members may be rotated with respect to one another when one of the containment barrier panels is being joined to a second adjacent one of he containment barrier panels to form a containment barrier wall. The male connecting member has least two elongate seal members (32, 33, 34) extending the length thereof, and constructed and arranged to be placed into sealing engagement with the female connecting member of the second barrier panel such that a fluid-tight seal will be formed between adjacent ones of the barrier panels for preventing the migration of groundwater and/or underground gases from out or into the waste material storage or burial site.

Containment barrier panel and method of forming a containment barrier

Structural panels (12) of extruded PVC and of stretched Z-shaped configuration and which can be driven into the ground include strengthening ribs (36-40) extending from the inner surfaces (34 and 35) of the opposed side sections (26 and 27). The ribs extend at a right angle to the side section bending planes (56 and 57) and at a right angle to the panel bending plane (64), thereby adding significant resistance to both compression and tension forces applied to the panel. The structural panels are driven into the earth to form a wall barrier, with the female locking element (43) being telescopically moved along the male locking element (42) of a previously installed panel. Distal strengthening rib (40) functions as a driving tongue to stabilize the position of the male locking element (42) during driving of the panel into the ground.

Reinforced structure panel for forming barrier walls

An extruded sheet piling (20) is disclosed. The sheet piling has a planar body panel (22) with a top end (23) and a spaced bottom end (24). A first continuous side edge (26) and a second spaced parallel continuous side edge (27) extend between the top end and the bottom end of the body panel, respectively. A first planar flat (29) extends away from the first side edge of the body panel, and has an elongate continuous male locking member (31) formed along an outside edge (30) thereof A second spaced parallel flat (34) extends away from the second side edge of the body panel, and has a female locking member (36) extending the length of an outside edge (35) and which is sized and shaped to snugly receive the male locking member of an adjacent sheet piling therein. An elongate structural reinforcing rib (42) is extruded as a part of the sheet piling along the outside edge of the first flat, and is spaced from and parallel to the male locking member.

Sheet piling extrusion

A decking extrusion for use in forming the deck members used to construct outdoor decks, docks, and similar structures is disclosed. The extrusion has an elongate planar base panel (7) with a first elongate side edge (8), and a spaced parallel elongate second side edge (9). At least one first elongate leg member (12) extends the length of the first side edge of the base panel, and at least one elongate second leg member (15) spaced from and parallel to the first leg member extends the length of the second side edge of the base panel. A first locking element (17) is formed at the distal end of the first leg member, and a corresponding locking element (30), sized and shaped to receive a second one of the first locking elements therein, is formed at the distal end of the second leg member. The extrusion may also be provided with an intermediate stiffening leg (126) having a transverse flange (127) formed at its distal end parallel to the base panel to add structural rigidity to the extrusion. Two identical ones of the extrusion are joined together to form an elongate deck member by placing the two extrusions in a 180.degree. reverse relationship with respect to one another such that the second locking element of the second extrusion is received on the first locking element of the first extrusion, while the first locking element of the second extrusion is received on the second locking element of the first extrusion, respectively, whereupon the extrusions are joined together in a snap-fit at the respective locking elements to form an elongate hollow box beam or deck member.
