Web offset lug dry-stack system

Abstract

A means to dry stack structural concrete block walls load bearing and non-load bearing) providing improved structural strength by grouting—especially partially grouting techniques and providing no web interference even in stack bonded configurations. Instead of having concrete block cells of different sizes—one on top of the other from one course to the next—during the dry-stacking process, the invention provides for the cells (cores) of the blocks to line up perfectly to provide a well defined column for concrete grout . . . making it easier, faster . . . and technically superior to the current mortarless systems using raised lugs (and other known methods) for face shell alignment. The improved cell (core) alignment is provided in both running bond and stack bonded dry-stack construction methods.
