Cracked Tilt-up Wall Panels Repaired
with Glass Fabric
Compton, California
Perhaps
the best testimony to the high quality of Fiber Reinforced Polymer (FRP)
products is that our competitors prefer using our products over their
own when it comes to fixing their own facilities. (Mitsubishi is a supplier
of FRP products for repair and retrofit of structures.)
A number of tilt-up wall panels in the Mitsubishi warehouse in southern
California were cracked. Rather than fixing the walls by crack injection,
the project engineer recommended using glass fabric to cover the cracked
regions. The 12,000 square feet of fabric was applied in strips, leaving
2–3 feet of space between each two consecutive strips. This resulted
in significant cost savings compared to crack injection, while covering
all cracks and providing significant strength for the walls.
The
completed walls were painted and as can be seen in this slide, it is difficult
to tell apart the repaired portions of the wall form the unrepaired parts.
This project was completed in November 1996.
