This document discusses retrofitting anchoring systems for masonry and stone facades. It introduces several products from CTP, Inc. for retrofitting, including the Stitch-Tie helical anchor, Grip-Tie 5300-R mechanical anchor, CT-16 brick tie, and facade-tie bracket. These anchoring systems provide in-plane strength and ductility to connect wythes, distribute loads, allow for movement, and reinforce facades seismically from the interior without needing exterior holes. CTP prides itself on being an American company that provides corrosion-resistant anchoring solutions.

Strictly structure repair-information is based on case studies.
This building is in s. Texas. Collapsed over night, no high winds. 50ftx20ft section fell. Picture was taken a week after it collapsed.
Brick to block composite walls. Has headers built into it.
Mobile alabama stone collapse, fell 17 stories and landed on this car. Popped off on a summer day. No one hurt.
Façade collapse gets peoples attention!
Building had been neglected and the corner stone has cracked. Due to moisture getting in this space and the area around it, the freeze thaw caused the corner to move and the brick next to the cornerstone has puckered. Sign of excess movement.
