Abstract: An innovative masonry block, such as a CMU, has a core of insulative material with masonry cladding, such as concrete, on lateral sides, and anchor elements, such as rigid bar members, may extend from the core to hold the cladding to the core. The core may also include a drain aperture extending from top to bottom, as well as a sloped top surface that serves to direct water to the drain. A plurality of such blocks can make a wall or other building structure having a pathway for water to travel through and out of the stacked blocks.

Abstract: Mortar and debris collection systems for cavity wall construction and/or walls constructed from concrete masonry units (CMU), for example, include a mesh body made of a material that is formed with circuitous paths therethrough making the body water-permeable. The mesh body is formed of a material having enhanced hydrophobic properties. The mesh body has a porosity sufficient to permit water to pass therethrough but insufficient to permit mortar and other debris to pass therethrough to weep holes or other water channels covered by the collection debris.

Abstract: An improved device for use in a cavity-wall construction includes a water-permeable body yielding a first-average opening size that is large enough to permit water to pass therethrough, but small enough to substantially prevent mortar and other debris from passing therethrough. The device includes a water-permeable material likewise adapted to permit water to pass therethrough, but also forms a barrier to insects which are of an effective size that is much smaller than the first-average opening size.

Abstract: A drainage system comprises an elongate flashing member, to be received beneath a course of CMUs, in use. A layer of water permeable material is attached to an upper surface of the flashing member. The water permeable material includes a longitudinal portion extending longitudinally adjacent a rear edge of the flashing member and a plurality of transverse portions extending transversely from the longitudinal portion to a front edge of the flashing member. A plurality of blocks of water permeable material are provided, each being positioned above the layer of water permeable material and extending upwardly into cavities of CMUs, in use. The water permeable material of the layer and the blocks has a porosity sufficient to permit water to pass therethrough but substantially insufficient to permit mortar and debris to pass therethrough so that water in cavities of the CMUs drains through the transverse portions.
