Fourth Avenue Junior High School – Yuma, Arizona
The building that the Fourth Avenue Junior High resides in was built in 1920 and was named a National Historic Landmark in 1982. When the building required a re-cover roof project, its National Historic Landmark status and student safety was top priority. Due to its history and age, care needed to be taken when completing the project. The products installed were required to be odor-less and could not damage the building. A second requirement for the project was that it be completed quickly and without lingering odors, because they planned to complete the installation over their holiday break. This is where SOPREMA products came into play.
Potomac Transportation Center – Dumfries, Virginia
To stay proactive, The Potomac Transportation Center, part of the Prince William County Public Schools, decided to apply a protective coating to their rooftop. Although there were no immediate problems with the current roof, it was determined that a preventative coating was needed on the aging roof before future complications arose. When it came time to select products for this job, the ALSAN® Coating line was selected due to SOPREMA’s relationship with Northeast Contracting Corporation, a 2018 Mammouth Club Member, and the expert local field technical services team.
