Westport Plaza Garage and Plaza Repairs

In 2016, WGI performed a condition assessment and provided repair recommendations for the extensive network of expansion joints at Westport Plaza. Westport Plaza is a mixed-use plaza in Maryland Heights (St. Louis). The Westport Plaza originally consisted of a plaza area with exposed aggregate concrete topping over a loose-laid butyl waterproofing system. In 1995, this system was replaced with a bonded, hot-rubber waterproofing system and pedestal pavers and was the 1996 Restoration Project of the Year by the St. Louis Concrete Council. Bob Tober was the project manager for this re-development.  

In 2017, a repair program began for the expansion joints. The project continued with Bob Tober in his move to WGI in 2018 and through completion in 2019.  

Project Highlights:

• Repair waterproofing system along expansion joint seals.
• Repair delaminated vertical and overhead concrete in the garage below.
• Update plaza pavers for aesthetics and accessibility.
