Abstract: A reinforced substrate is provided, so that the substrate is better able to withstand compression forces imposed on it by a structure bearing upon it.

Abstract: A prefabricated shearwall including a central diaphragm having a height generally defined by top and bottom edges, and a width generally defined by a pair of end sections. The diaphragm further includes at least one corrugation extending in the height direction at least partially between the top and bottom edges. The corrugation increases the ductility and ability of the shearwall to withstand lateral forces such as those generated in earthquakes, high winds, floods and snow loads. The various components of the shearwall may be affixed to each other by welding, bolting, screwing and/or gluing.

Abstract: A connection is provided between a holder and a plurality of anchor bolts by means of a template. The holder is typically a form board for a cementious member such as a foundation. The template is releasably attached to the form board. The template is formed with a central elongated support, and a plurality of pairs of primary and secondary anchor bolt receiving platforms connected to the central elongated support. The pairs of primary and second anchor bolt receiving platforms are spaced along the central elongated support from each other. Each of the primary and secondary anchor bolt receiving platforms has an opening therein for receiving one of the anchor bolts there through, the openings in each pair of primary and secondary anchor bolt receiving platforms being in alignment so as to receive the same one of the anchor bolts.
