Project description: Westfield is doing a $750 million expansion on their Topanga Canyon mall. One part of the expansion includes building an underground tunnel from a main road under shopping area to a parking structure. Freedom worked closely with Westfield to design and spec a waterproofing system that would last and speed up the construction of the project.

Application: Westfield had a tunnel they need to move cars from a busy street under the mall to a parking garage. The total surface are of the tunnel was 50,000 +. They were going to be pouring in sections and needed to be able to apply a waterproofing system on some areas in less than 28 days of the pour. For these areas that were older than 7 days of cure but less than 28 days of cure we used 16 mils of FT-6600 MVR. After the primer was applied a total of 120 mils of FT-2202 polyurea was applied. A “belt & suspenders” approach was used so drain board was hung on top of the polyurea to help move the water away from the walls and ceiling.
