MISSION CRITICAL PROJECT No. 5:
MADERO successfully executed the turnkey task of Corrosion Protection, Impermeabilization, and Structural Rehabilitation of a highly deteriorated concrete infrastructure, in a quality and cost effective manner, no safety issues, and within the agreed work schedule with the customer. This infrastructure was the only discharge channel of the potable water treatment plant for the city’s 380,000 inhabitants, which was built in 1940.
This project was the first world-class rehabilitation of its kind in Latin America by MADERO and the client. This project only allowed three mini-stops with a total project duration of 48 hours. The scope of work was critical path at all times. The project milestones and compressed work schedule was extremely aggressive. There was no room for errors or omissions because the city’s drinking water tanks were of limited capacity, and the municipality could not guarantee the water supply to the inhabitants if the work exceeded the agreed hours.
PRODUCT APPLICATION
The surface preparation was performed with wet sand. During the Engineering Assessment Inspection, a large number of structural cracks, holes and substrate deterioration mechanisms were discovered, including corroded metallic components. A large corner wall area of the canal had significant structural deterioration. MADERO manually rebuilt it with composite materials (Warren Epoxy and Fiberglass). The bulk of the Warren Epoxy coating was spray applied. Localized structural deteriorated areas were manually repaired via trowel method.
CONCLUSION
The Warren Epoxy stopped the significant water leaks that saturated the ground, stopped the sinking of the water treatment facility, and provided structural integrity and impermeabilization to the channel.
This rehabilitation project had a great return on the investment because the project was paid off in nine months. Furthermore, by eliminating the significant water losses, the customer had an immediate and significant increase in water availability and capacity. MADERO’s execution of this turnkey Mission Critical Project was a total success.
