  • Publication number: 20210164187
    Abstract: A sheet piling filler-corner member includes one or more female couplings for engagement of male couplings of connected sheet pilings, and one or more male coupling members for engagement within female couplings of connected sheet pilings. Selective attachment of sheet pilings using the filler-corner member, and/or modification of the filler-corner member into different configurations allows the filler-corner member to universally function as a spacer or filler for adding length to a sheet piling assembly, as a corner coupling, or as a gender-change adapter between sheet pilings.

  • Patent number: 8753043
    Abstract: A system and method for installing sheet piles using active gripping along side portions of the sheet piles. A sheet pile profile including first and second locking profiles and a gripping flange enables engagement of the sheet piles onto a mandrel for installation. Double engagement flanges on the locking profiles and an expandable connection between adjacent sheet piles provide improved resistance to fluid passage.

  • Publication number: 20090188180
    Abstract: A composite wall system includes a foundationless wall substructure such as a sheet piling wall with a base portion embedded in the ground and an exposed portion extending above the ground, and one or more fascia panels or sheets such as synthetic simulated stonework panels applied over the foundationless wall substructure. Components of the wall system prevent debris from entering between the wall substructure and the fascia panels, and in seawall applications prevent water incursion and resist wave action.
