Or Saves More Time & Labor.
Our simple, lightweight Blok-Flash system has always been your best defense against moisture damage and mold growth. Now it's your best time & labor saver, too!
Saves over half the labor & materials of thru-wall membrane flashing in a multi-wythe course, while delivering up to 10 times
stronger bond and eliminating the need for multiple sizes of Architectural CMU. Works with 8", 10", and 12" exterior CMU. Installs easily in reinforced walls. NEW Drainage Matte eliminates the need for pea gravel. Lightweight & compact for easy shipping, handling, and storage. 40% recycled polypropylene can help your project qualify for LEED certification. Stronger than flashing, and it installs in a flash.
Drop Blok-Flash pans onto
each 1st course block, with
Weep Spouts protruding.
Grout according to instructions.
then lay 2nd course.
Press a lightweight, polyester-mesh
Drainage Matte into each cavity of 2nd
course block to capture mortar/grout
droppings. (No pea gravel.)
With new Blok-Flash", it's easier than ever to protect your CMU exterior walls, against moisture damage & mold growth... while protecting yourself against the high costs of installing other moisture control systems!
