Publication number: 20210164187Abstract: 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.Type: ApplicationFiled: December 2, 2019Publication date: June 3, 2021Applicant: CMI LIMITED CO.Inventor: Steven E.

Publication number: 20090188180Abstract: 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.Type: ApplicationFiled: January 27, 2009Publication date: July 30, 2009Applicant: CMI LIMITED COMPANYInventors: John E.
