In 2018, the Vancouver International Airport (YVR) celebrated a record-breaking level of growth. Reaching their 25-million-passenger milestone two years ahead of forecast, YVR saw an increase in passengers since 2017. That increase was over 7%, and such a big leap was mainly thanks to expanding services from YVR’s airline partners. That included the growth of Air Canada who had made YVR their premier transpacific hub. This level of growth has only been expected to get bigger as forecasts for YVR indicate that the airport will reach 31 million passengers annually by 2022.
To ensure that YVR could continue supporting the ever-increasing number of passengers, the Vancouver Airport Authority chose to expand the airport. This expansion (known as the Pier D expansion) gave YVR another eight wide body gates. Four of those gates were bridged gates, allowing YVR to make room for more planes, including large aircraft, such as the A380, which come with a 260-foot wingspan. The other four gates were remote stand operation gates. These added space for more buses, increasing how many passengers YVR could transport across the airport.
At the same time, the Vancouver Airport Authority also added a wide variety of other new features, including a private nursing room, a pet relief area, vision strips designed by a Musqueam artist, refill stations for hot and cold water bottles, a pond water feature, and an abundance of outlets and charging stations.
It was the largest terminal expansion YVR had seen since 1996, and it wouldn’t have been possible without thorough, permanent concrete waterproofing.
Such waterproofing was critical as YVR is an airport located in Richmond, British Columbia, a region that is very close to sea level. As a result, a number of YVR properties could be found at that level and needed protection from water penetration. That was no different for the Pier D expansion.
Having worked with Kryton before in past projects, however, the Vancouver Airport Authority knew they could count on Kryton’s Smart Concrete® solutions to provide them with the perfect protection from water. As a result, their construction team added around 300 m3 (392.34 y3) of Kryton’s waterproofing admixture, KIM, directly into the concrete for the expansion project’s pond water feature, elevator and escalator pits, utility chambers, sumps, and planter pit.
This admixture transformed the concrete from a stationary material to one that could protect itself from water and waterborne contaminants. At the slightest sign of moisture, the concrete would have the ability to use Krystol® technology to chemically react to it and nearby unhydrated cement particles to form interlocking crystals. These crystals would then fill up any capillary pores and micro-cracks, effectively blocking any spaces that water and any contaminants within it could go through.
This protection will work for the entire KIM-treated structure as KIM permeates throughout the concrete during batching. And it will last for the lifetime of the structure as the Krystol technology within the admixture will remain dormant until activated by the presence of moisture.
It significantly reduces the risk of water passing through the concrete. But the concrete’s joints could still act as an entryway for moisture. So to mitigate that possible risk as well, the Vancouver Airport Authority’s construction team treated the joints with Kryton’s Krystol Waterstop System. Using the system’s triple protection, the team applied Krystol Waterstop Treatment™ to the concrete around the joints, installed the Krytonite™ Swelling Waterstop, and then applied the Krystol Waterstop Grout™. The treatment would provide additional waterproofing protection while also protecting the rebar inside the concrete from corrosion. At the same time, the waterstop would act as an additional barrier that could swell in the presence of water to seal construction joints away from the moisture. And finally, the grout would add fiber reinforcements to reduce the possibility of the concrete structure shrinking or cracking.
To add to that support, Kryton also provided the construction team with assistance from their Krystol Assurance Program. Through the program, the team received an in-depth design review, site training and inspections, and a 10-year labor and material warranty for leaks. All of which led to the team successfully completing the Pier D expansion with no concern for leaks or other moisture issues.
Krystol Internal Membrane (KIM) is a hydrophilic crystalline admixture used to create permanently waterproof concrete.
The Krystol Waterstop System is used to permanently waterproof concrete construction joints, pipe penetrations, tie holes and control joints. The Krystol Waterstop System works where other waterstops routinely fail. Kryton is the only integral waterproofing company that offers fully integrated concrete waterproofing solutions.
