To meet the parking requirements, the lowest parking level and building slabs had to be constructed below the existing water table necessitating a solution capable of withstanding high hydrostatic pressure.


Hycrete’s System W provided a superior solution in terms of cost effectiveness and accelerated construction schedule. Using Hycrete eliminated the need for waterproofing membranes and saved GLY a significant amount of time and money.


The construction schedule was shortened, saving Expedia time and money. By using Hycrete's System W, they also received a non-absorbent concrete surface that is easy to maintain with a 10-year performance warranty. Overall, the property owner gets a company they can count on to keep their building dry and continue operations without interruptions. Additional Benefits • No Additional Labor Required • Disruptive Maintenance and Down-Time Avoided • Warranted-Performance
