DRISTICT 5 BRIDGE
In the United States, each state has their own Transportation Department that’s responsible for the maintenance & upkeep of their bridges (as well as the design & construction of their new bridges). The Idaho Transportation Department (ITD) is continually looking for better ways to protect their highway bridges from premature deterioration caused by the harsh winters, and the snow & ice melt products that are used to keep the roads drivable.
GEORGIA D.O.T. TEST BRIDGE
Alchemco faced the challenge of getting their BridgeDECK waterproofing systems approved for Georgia state DOT's Qualified Products List, necessary for bridge construction and maintenance. Each state's DOT operates independently, requiring convincing evidence of product effectiveness, including lab tests and field evaluations. Alchemco pursued approval by requesting evaluation from the Georgia DOT, leveraging their membership in the AASHTO TSP-2 ITD Task Force. After evaluation, Georgia DOT chose to field test BridgeDECK on a small bridge, which was installed by CW Matthews, highlighting its safety, speed, and ease of application.
NHAT TAN BRIDGE
The challenge in this ambitious project was to establish long-term waterproofing for a 2.3-mile bridge spanning the Red River, linking Hanoi City Center with Noi Bai International Airport and the northern provinces. Construction commenced in 2007, culminating in completion and an official ceremony in January 2015. With eight lanes and over 1 million square feet of high-strength concrete, traditional temporary protection methods like Silanes or Methyl Methacrylates were deemed inadequate for the project's longevity goals. Instead, the owners opted for the award-winning TechCrete 2500, leveraging its EMSS technology for decades-long protection, environmental friendliness, economic viability, and efficient application to meet construction deadlines.
RED RIVER HIGHWAY BRIDGE
The Louisiana Department of Transportation and Development (DOTD) initiated field testing of Alchemco's concrete waterproofing technology on a section of Old Hwy 61 near St. Francisville in February 2020, seeking enhanced and durable solutions for protecting their state's concrete highway bridges. In contrast to competitive products like Methyl Methacrylate and Epoxy Overlays, which are costlier, have shorter performance lifespans, or require more resources for application, Alchemco's BridgeDeck concrete waterproofing solutions offer a more economical and efficient alternative. Following successful testing and monitoring, Louisiana DOTD proceeded to specify the BridgeDeck Waterproofing System for a full bridge application spanning 123,000 sq. ft. This system ensures true long-term waterproofing protection for the bridge deck, boasting environmental friendliness and certification for potable water use, meeting stringent standards set by UL and NSF-61.
In 2017, Colorado State University faced an urgent issue with concrete deterioration in parts of their newly constructed football facility, Canvas Stadium, raising concerns as such structures are typically designed for a lifespan of 50 to 75 years. The challenge was to halt the ongoing decay and prevent future deterioration to safeguard their investment for decades to come. While liquid-applied coating systems were the typical solution, they posed drawbacks such as slow application, high cost, and limited protection duration. Leveraging the success of the gel-forming TechCrete 2500 Waterproofing System in resolving leaking issues at the CSU basketball arena, the Facilities Department opted for the same technology to address the football stadium's premature concrete deterioration. The system's long-term protection, one-time application, preservation of concrete appearance and slip resistance, along with its cost-effectiveness, eco-friendliness, and rapid application, made it the ideal choice, offering substantial value to the university.
NEW JERSY D.O.T. BRIDGE
Departments of Transportation nationwide face the challenge of preserving existing bridges to extend their service life. In New Jersey, corrosion inhibitors are a key tool, with regular re-spraying every five years as part of bridge maintenance budgets. The New Jersey DOT recently awarded a contract for 27 bridges, totaling 4 million sq.ft., to apply BridgeDECK CorrosionBlok. This decision was based on the product's approval since 2005 and its perceived speed of application and cost-effectiveness by the contractor bidding for the project.
PITTSBURGH INTL AIRPORT
The challenge at Pittsburgh International Airport (PIT) arose in 1988 when almost 1 million sq. ft. of the existing runway surface needed long-term protection due to cracking and spalling caused by freeze/thaw conditions and de-icing salts. After evaluating various options, including cost-effectiveness and speed of application, the specifier determined that the TechCrete 2500 Waterproofing System was the most suitable solution. While few alternatives were available at the time, spray-applied concrete sealers and Methyl Methacrylate-based products were considered, but deemed inadequate or impractical. The TechCrete 2500 provided long-term waterproofing, the ability to seal existing and future cracks, and a crucial advantage in speed of application, allowing the runway to be treated within just 3 days, minimizing disruption to airport operations.
TREN MAYA RAILWAY
The Tren Maya Project (Mayan Train) consists of approximately 950-miles of new railroad being built along the coast and through the tropical rainforest of the Yucatan peninsula in Mexico. It is the country’s the largest infrastructure project, with an estimated cost of over $10 billion dollars. It’s configured in a large loop that connects all of the main cities and villages along the coast of the Yucatan Peninsula and includes 18 train stations being built along the route (including a station at the new international airport under construction in Tulum … where Alchemco’s Waterproofing System was selected as the roofing system of choice for concrete roof deck on Airport Terminal #1).
