The wythes are bonded together with masonry ribs or crosswalls in such a way that, structurally, the wythes function compositely—as though the entire thickness is effectively solid. The use of reinforced diaphragm walls allowed support of the tall sidewalls and gable ends. Figure 2 shows a cross-section of a typical diaphragm wall. The reinforced wythes can be fully or partially grouted. The exterior face can be constructed with a weathering face, like a conventional single wythe wall, or finished with a veneer.

The crib is a framework made of wooden horizontal and cross beam alignment. Cofferdams are advantageously constructed where a large area of site is to be enclosed and the hard bed is at reasonable depth. Circular Circular cellular cofferdams are composed of circular arcs that are connected by straight diaphragm walls. Circular types are large circle-shaped cells, connected to one another by slightly smaller circular cells. For cofferdams required to enclose larger areas in deep water, single wall type becomes uneconomical as larger sections of trussed struts would be necessary to resist the water pressure. The thickness of wall should be equal to the depth of water up to 3 m.
