Profile: Benjamin Obdyke, Inc. offers residential roof ventilation, and wall moisture management building products. Our moisture management products include ridge vents, rainscreens, and other moisture management related building supplies. Blockade™ is designed specifically for use in brick wall cavities. The entangled matrix design of the Blockade™ mortar deflection system blocks mortar from clogging the weep holes, and allows excess moisture to flow freely out of the wall cavity. The result is a brick wall that is built to stand the test of time, and remains free from the deteriorating effects of mold & mildew. Home Slicker Stone & Stucco® is a vertically channeled rainscreen that has been specifically designed for use with manufactured stone, natural stone, stucco, and masonry applications. Each roll contains the patented Home Slicker three-dimensional matrix bonded to a fabric, which prevents mortar from entering the wall cavity during cladding installation. Home Slicker 10 Stone & Stucco is created to comply with building codes.
