Hugo L. Black U.S. Courthouse in Birmingham, Alabama is forced to undergo $900,000 in repairs to their failing external membrane. Water has been leaking into the basement, and crews are now tasked with the difficult job of replacing the membrane. The project involves demolishing the plaza pavers, repairing the concrete, embedding new water proofing membrane, and installing new pavers. Work on the project is forecasted to continue until March, 2013.
When external membranes are used in the initial construction (rather than an internal crystalline membrane such as Krystol Internal Membrane), over time the membrane WILL break down and need to be replaced. As this courthouse example shows, this can be extremely costly and time consuming. This courthouse will have to have crews coming in and out of the basement for months, and occupants will have to endure noisy demolition during the demolishing of the plaza pavers.
To repair this situation, we would recommend Krystol T1 and T2 Surface-Applied treatment, which have been proven time and time again, to successfully waterproof a leaking concrete structure that has experienced a an external membrane failure.
Cypress Mountain’s reservoir was one such project. Hear what Steve Williamson, Director of Operations at Cypress Mountain had to say about this solution.
