Core offering

Blok-Lok manufactures proprietary masonry anchoring systems, flashing products, air barriers, and repair/restoration systems for commercial and residential masonry construction projects across North America. The portfolio spans Flex-O-Lok ties, joint reinforcement, rebar positioners, control joints, concrete inserts, veneer anchors, partition top anchors, copper and self-adhered flashings, vapor-permeable air barriers, and patented non-destructive masonry repair systems (Torq-Lok, Spira-Lok, Panel-Lok, Brick-Lok). These products are specified by architects and purchased primarily by masonry contractors, distributors, and building restoration professionals.

Product overview

Blok-Lok is a manufacturer of construction building envelope products focused on masonry systems, flashing systems, repair and restoration systems, and air barrier systems. The company operates as a single unified product portfolio rather than a platform-plus-modules architecture. Their Masonry Systems product line includes veneer anchors (HB-213, HB-213 HS, BL-407, BL-507, BL-607), Flex-O-Lok ties, joint reinforcement (ladder and truss types), rebar positioners, control joints, concrete inserts, and masonry accessories. Their Flashing Systems include copper composite flashings (Copper NA, Copper SA), membrane flashings (TeXtroflash, Flex-Flash with Elvaloy Kee), metal flashing, and accessories (termination bars, corners, end dams, drip plates, primers). Repair and Restoration Systems include Brick-Lok, Panel-Lok, Spira-Lok helical wall ties, and Torq-Lok torque-activated anchors. Air Barrier Systems include ENVIRO-BARRIER products (standard and VP vapor permeable variants), AIR-TIGHT 40 sheet membrane, and HB Sealant. The products work together as complementary building envelope solutions for moisture control, structural reinforcement, and energy performance in masonry construction.
