Mall of America EIFS facade sealed with Backerseal and liquid sealant

The vast panelized EIFS facade of the Mall of America contains over 200,000 LF of joint that faces the extremes of winter and summer weather of the northern US plains.

Backerseal installation as secondary sealant in Mall of America

The Mall of America opened in August of 1992 and was the largest shopping mall in the country in terms of total area as well as number of vendors. With a total floor area of 4,870,000 square feet, 200,000 LF of EMSEAL’s Backerseal was needed to seal the external panels of the facade of the building. Backerseal protects the building from weather and water damage and resists air pressure differentials as well as Minnesota’s intense winters.

The massive panelized facade of the Mall of America received over 200,000 LF of Backerseal as a secondary sealant to liquid silicone applied in the field.

To order Backerseal in sizes to suit joint variations, the contractor did a survey of a small, typical wall area.

From the percentages of each size in the survey, the contractor ordered materials accordingly. EMSEAL kept the job continuously supplied based on weekly usage.

5-gallon pails marked with the material size were tied to the rails of the utility lift basket. From these pails the installers pulled Backerseal to suit the joint sizes being treated.
