Located on Yeongjong island, about 50 km from Seoul, South Korea, the Incheon International Airport is 60 times the size of a football field and boasts the second tallest control tower in the world. Its two runways allow takeoff and approach over the sea, and the terminal facilities are designed to handle 27 million passengers annually.
GCP Applied Technologies is proud to have been associated with this prestigious, state-of-the-art airport construction project. All GCP Applied Technologies materials were installed by experienced, trained applicators, and the architect and general contractor were delighted with the resulting quality and timeliness of completion.
Challenge
Protecting against fire and water
Protecting such a structure from the transgressions of fire and water is an important issue. The choice of fireproofing and waterproofing materials used had to take into account not only product quality and performance, but also application efficiencies and quality control on site.
During airport construction of the control tower, which is one of the most prominent features of the project, the designers were challenged to achieve a very high quality finish to the concrete surface. The concrete supplier, SsangYong, tested a large number of admixtures from different companies to assess performance in meeting the plastic and hardened concrete requirements.
Solution
Proven in place fireproofing
SsangYong selected MONOKOTE® fireproofing and GRACE ICE & WATER SHIELD® roofing underlayment for many parts of the airport construction. MONOKOTE®’s proven in place performance has made it one of the most widely applied fireproofing materials in the world.
About 51,000 m2 of MONOKOTE® MK®-6/HY® and MONOKOTE® Z-106 were used extensively in the main terminal building, the general hangars, and the Korean Air Cargo Centre. More than 130,000 m2 of GRACE ICE & WATER SHIELD® roofing underlayment were used in the transportation center and the main terminal roofs.
As for the control tower, SsangYong chose concrete admixtures from GCP, which proved to deliver the best overall performance. These concrete solutions helped by providing slump retention and very good off form surface finish. There was no need for subsequent surface treatment. GRACE ICE & WATER SHIELD® underlaymentprovides the assurance of a tight seal around penetrations from the metal roof surface, which pass through the assembly to the structural elements below.
Throughout the airport construction project, GCP provided full support to the applicators, architect, and general contractor. Its technical team made frequent site visits to routinely check bond strength and applied thickness and to provide equipment maintenance.
As a result of its success on the Control Tower, GCP delivered similar solutions for the construction of the high bridge.
