mastersealpr.com > About Us

Master-Seal's concept was brought about through experience in the petrochemical industry during the 1970's and 1980's. Through many iterations and field experiments, its formula was perfected and lastly became a leading product for the demanding waterproofing industry in Puerto Rico and the Caribbean.

Industrial Roofing, Inc. proudly operates as a family business from Cataño, Puerto Rico. We wish to thank all of our clients, friends and suppliers for making Industrial Roofing, Inc. and Master-Seal continously set the bar for quality and perfomance of waterproofing systems in Puerto Rico.
