Dubai International Airport is one of the world’s fastest-growing airports, and is in the midst of a long-term plan for expansion. Terminal 3 was recently completed after three years of construction, and features 3.8 million square feet of a Brazilian stone called Panha Fragola Corcovado, or “PF”. PF presented a serious sealing challenge because the stone contains soluble pyrite (an iron sulphide) which can absorb water from the mortar bed during curing and cause severe discoloration. IKAN, Inc. a local distributor of Aqua Mix care and maintenance products, recommended a six-sided sealing solution in order to protect the stone from moisture throughout the 28-day curing process.
Extensive testing was conducted by Aqua Mix technical experts, with two new products that were not even on the market yet, UltraSolv® and Econo-Seal™. First, local materials were used in order to duplicate the installation conditions, while confirming with control groups that the discoloration from soluble pyrite would in fact occur without proper sealing. Next, IKAN preformed submersion and mortar bed tests with PF stone sealed on all six sides with EconoSeal and UltraSov. Both sealers performed impressively, keeping water at bay for the required 28 days and preventing discoloration. Finally, tests were done to prove that neither sealer would compromise shear bond strength.
After successful testing, EconoSeal was selected for the initial six-sided sealing, with UltraSolv specified for final sealing of the installed surface. Stone was laid out, sealed on six sides with Econoseal, and cured for 24 hours prior to installation. UltraSolv was applied to the finished surface just prior to completion of the entire terminal. During this period both UltraSolv and EconoSeal products were launched for sale internationally.
IKAN assisted the primary stone contractor, Al Habtoor, throughout the 2-year process, providing onsite support, quality control and education for the ever-changing staff of over 400 tradesmen imported from other countries to work on the project. The result is a stunning, pristine installation that has no trace of soluble pyrite or any other staining. In fact, the sealing project was so successful that Aqua Mix sealers, from Custom Building Products, will be used on the next new terminal at Dubai International Airport, already underway.
