WGI reviewed the exterior walls to identify repair needs. The visual survey was performed from the ground and the roof and included a close-up examination from an articulating man-lift. Isolated concrete delaminations were observed, as well as concrete cracking and corrosion of the steel lintels.
Repairs included:
- Replacement of delaminated concrete
- Sealing of cracks
- Repointing of deteriorated and cracked mortar joints
- Replacement of spalled and cracked terra cotta accents
- Replacement of steel lintels and installation of new through-wall flashing at the window heads
- Removal and replacement of terra cotta units with new cast stone units at the window heads
Project Highlights:
- Sealant Replacement
- Re-pointing
- Brick Masonry Repairs
- Lintel Replacement
