An apparatus and method for endwise connecting subterranean barrier members is disclosed. The apparatus includes at least two barrier members with each barrier member extending between top and bottom edges. Further, each barrier member has a side first edge having a flange defining a first connector and an opposed second side edge having a channel defining a second connector. The channel is sized and shaped to receive the flange of an adjacent barrier member in slidable interconnection therein. The apparatus further include a first side panel shaped to lie against a first side of the barrier members, a second side panel shaped to lie against a second side of the barrier members and a bridging plate located between the first and second panel members so as to bridge a gap therebetween, wherein the gap has a width corresponding to a width of the first and second barrier members. The associated method is directed toward creating the apparatus.

A convertible capping system and methods of use thereof for capping a top portion of a sheet piling wall or other structure. A top panel of the capping system includes a widthwise spaced array of longitudinally extending parallel connection ribs, and defines an initial width at least equal to or greater than an intended final width, whereby a user can cut the top panel down to a desired final width corresponding to the thickness of the wall. A pair of side flanges have engagement features configured to attach to the connection ribs of the top panel after adjusting the width of the top panel, to assemble the capping system. A wave diverter and/or structural reinforcement system can optionally be provided with the convertible capping system or sheet piling wall.

Seawalls and methods for making seawalls are disclosed. A seawall may include a concrete footing, with a first plurality of anchorages disposed in the concrete footing. A plurality of precast concrete tee beams may include single-tee beams and/or double-tee beams. Flanges of the tee beams may be positioned to form seaward and landward faces of the wall, and stems of the tee beams may be coupled to the footing between the seaward and landward faces. A second plurality of anchorages may be disposed at tops of the stems. Elongate steel components extend through the stems, and are tensioned between the first plurality of anchorages and the second plurality of anchorages. Interior fill may be disposed between the seaward and landward faces. One or more wave deflectors may be disposed above the tee beams.

A system that includes a plurality of front faces configured to be arranged end-to-end in a series. Adjacent front faces are connected together by a different X-shaped or X-wye connector that facilitates installation of reinforcement tail walls. At least one tail wall is connected to each connector. A redundant reinforcing tail wall may be constructed and attached to one of the connectors to provide alternative load path(s).
