KEYWALL
Galvanized Wire Mesh Reinforcing
LOCKS
28 mortar locks to the block foot
The more locks, the more resistance to shrinkage cracks. Movement is restrained at each of Keywall's mortar locks. No one lock has to restrain more than the movement in 34" of block.
ANCHORS
14 inches of mechanical anchors to the block foot
Mechanical anchoring restrains thermal movement and shrinkage, too. No other reinforcement comes close to offering the amount of mechanical anchor that Keywall does.
BONDS
22 square inches of bonding surface to the block foot
The more metal in surface contact with the mortar, the better the reinforcement. Keywall's 22 square inches per foot of block is about 55% more than a pair of 3/16" truss rods, about 96% more than a pair of 9-gauge truss wires.
