A vertical joint system for substrates is formed with joints and which engaged by relative motion in a direction perpendicular to major surfaces and of the substrate. The joints are configured to enable relative rotation of up to 3 degrees while maintaining engagement of the joints. The joints and are further configured to form two locking planes one on each of the inner and outer most sides of the joint. Engagement about the locking planes is provided by transverse outward extending surfaces. At least one surface in each pair of engaging surfaces is smoothly curved. The joints and can be further arranged to provide a third locking plane parallel to and between the locking planes. The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.

A system and device for mounting and protecting exterior sheathing on a building. The system comprises a sheath-protecting bracket coupled to a wall with a sheath panel coupled to the wall with a bottom edge of the sheath panel positioned in the sheath-protecting bracket. The sheath-protecting bracket comprises a back plate, a bottom plate coupled to a bottom edge of the back plate, a front plate with a bottom edge coupled to the bottom plate. The sheath-protecting bracket has one or more spacers coupled to a front of the back plate to support the sheathing while allowing any moisture in the sheathing to weep out and fall into gaps above the bottom plate. A plurality of drain holes through the bottom plate allows water to drain out of the sheath-protecting bracket.

An apparatus and method for a wall panel system having a plurality of wall panels arranged within a framework. The wall panels may include a plurality of retention devices releasably engaging the framework to position the wall panels relative to the wall panel system. One or more of the retention devices may be actuated to engage and disengage from the framework. The wall panel system may include trim releasably engaging the framework.

A stay-in-place lining is provided for lining a structure fabricated from concrete. The lining comprises a plurality of panels connectable via complementary connector components on their longitudinal edges. Each panel comprises a first connector component on a first longitudinal edge thereof and a second (complementary) connector component on a second longitudinal edge thereof. The lining comprises at least one edge-to-edge connection between the first connector component of a first panel and the second connector component of a second panel, the edge-to-edge connection comprising a protrusion of the first panel extended into a receptacle of the second panel through a receptacle opening. The receptacle is shaped to prevent removal of the protrusion from the receptacle and the receptacle is resiliently deformed by the extension of the protrusion into the receptacle to thereby apply a restorative force to the protrusion to maintain the edge-to-edge connection.
