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.
