Dubai International Airport Expansion, Phase II

Waterproofing Solutions Products Nigeria Dubai International Airport Phase II

The terminal building is underground and subject to a water pressure > 3 bar. The terminal building has a concourse on the air side and a car park on the land side. The area in between is a taxiway for aircrafts including the new Airbus 380’s which will load the structure with a weight > 500 tons each.

The project specification required a loose laid passive synthetic membrane to allow movement in the substructure over time. The membrane had to have a capability to be tested and inspected before placement of concrete. The structure needed to be compartmentalized to restrict the spread of leaks if they occurred.

The structure needed a curative system in place which would assist speedy rectification, with the minimum disruption. Most of all the requirement was to provide a system from a single source to ensure that the various elements of the system worked in harmony.

Logistics management was critical in the supply of close to one million square meters of waterproofing and accessories, to meet the challenging construction schedules.

MasterSeal 909 re-injectable hoses and MasterSeal 901 resin were the products of choice for the curative measures, this joint protection system was the only one that successfully demonstrated the capability to be reinjected. The resin has been used successfully to control the leaks in numerous structures worldwide.

The membrane is synthetic PVC, to allow increased resistance to damage as the structure settles or moves. The welding of PVC waterstops to the waterproofing membrane provides the capability of compartmentalizing the loose laid waterproofing membrane.

The MasterSeal 914 epoxy grout was used to cap the pile heads and sandwich the membrane. This allows movement at the interface of the pile head and the structure. The MasterEmaco S 466 cementitious repair grout was used to reprofile and repair the pile heads, because of its superior flow characteristics and strength.
