Exterior Concrete Restoration
The Dominick V. Daniels (DVD) Processing & Distribution Center (P&DC) is one of the largest postal facilities in the New York Metropolitan area, having a floor area of over 800,000 SF. Having a long and successful track record in building envelope repairs and restoration, CTS was engaged to investigate a serious problem with the building exterior. The exterior concrete columns, banding, and canopies were beginning to spall and fracture. Reinforcing within the concrete components was rusting and the concrete that encased it was fracturing and, in some cases, falling to the ground. The CTS Group quickly determined that the problems with the exposed exterior concrete were associated with the penetration of chlorides and the carbonation of the concrete surfaces, and designed and supervised the meticulous concrete restoration needed.
Relevant Project Data:
- Over 130,000 SF of concrete surface was repaired, treated, and coated.
- One of the treatments included an application of a corrosion inhibiting impregnation that penetrates and protects not only the repair area, but also the surrounding concrete from future corrosion due to latent damages.
- The final protective coating is a decorative, crack-bridging coating, which protects the entire structure from the harmful effects of carbonation and water ingress.
