Match Keywall Reinforcement to the mortar strength and save
Use Truss-Type Keywall with high strength mortar. Truss-Type Keywall is not a money saver, but it does do the best job of reinforcement when high strength mortar is specified. The tremendous bonding power of high strength mortar makes excellent use of the extra steel in our truss-type reinforcement, as shown by lateral pressure tests conducted at the University of Toledo. Tests also showed that reinforcing every other course is as effective as reinforcing each course.
Keywall Multibond comes in rolls that are easy to hand carry, roll, convey, or wheel. One roll reinforces 200 ft.
Toledo University tests show that Keywall Multibond is unsurpassed when used with regular mortar. Multibond gives you 96% more bondling surface than 9 gauge truss, 55% more than 3/16" truss, plus 28 mortar locks per 8" block.
