Terminal 3 at Changi Airport, Singapore, has been completely waterproofed with PENETRON products in preparation for the next phase of construction. The completed project will span 7 levels with 28 gates and an additional 1,800 parking spaces.
Penetron completed the initial construction phase of at Singapore's Changi Airport, which is being built by the Civil Aviation Authority of Singapore. PENETRON ADMIX was used to treat the concrete substructures of Terminal 3. The new terminal, when completed, will spread over seven levels, including a three-level basement, house 28 aircraft boarding gates and add another 1,800 parking spaces. The airport is expected to be completed by 2007.
"It's crucial to choose a right waterproofing system for such a fast track project," said Gary Loh, Managing Director of Reverton Engineering. "Meeting our deadline is important, but achieving a watertight structure is our primary objective." The Penetron System was chosen because it heals and seals concrete, according to Mr. Loh, and because it's easy to use and can be applied flexibly even to wet concrete. "That kind of usability is what we count on to help us meet demanding schedules and deliver the results we want.
Robert Revera, President and CEO of the Penetron Group, says "it was a challenge to meet the schedule. But we worked well with Reverton Engineering because they operate with the highest standards in the design-and-build construction industry. Our partnership with them is grounded in mutual confidence that performance standards will always be met in these mission-critical projects for international governments."
To waterproof and protect the entire foundation and slab (140,000 m3) of Terminal 3, PENETRON ADMIX was added to the concrete mix. In addition, PENETRON (as a slurry) and PENECRETE MORTAR were also applied. The Penetron Waterproofing System uses chemicals that fill cracks, voids and spaces to prevent any penetration of moisture while allowing the concrete to breathe.
