About The Owner

Marla Cosburn is President of DRE Industries Inc., a manufacturer, distributor and manufactures’ representative of waterproofing products.   

About the Owner

After attending McMaster University, Marla earned a Post-Graduate Management Marketing Diploma at Humber College. She was among the first to receive the Certified Technical Representative (CTR) designation in Ontario. Marla began working for DRE in 1993, and eventually took over the company in 1999. 

DRE started as a family business: Marla’s mother, Elva Edgar, was one of the founding partners. In 1983, when a colleague visited the World of Concrete and found a unique and interesting product called Chem-Trete, he became the Canadian distributor and began the company. A year and a half later, Doug Edgar, Marla’s father, was looking for a new opportunity after a long and successful career in retail management. After working several months promoting and selling the impressive product, he bought the business. DRE still works with Chem-Trete today - 38 years later and several of the early contractors DRE worked with continue to be customers.

Passionate about providing excellent service to her clients and customers, Marla loves working on projects from the earliest design stages through to installation and beyond. 

Marla’s many accomplishments include being the first female president of both the American Concrete Institute (ACI) Ontario Chapter, and the Sealant and Waterproofing Association, for whom she still sits on the Board of Directors. She has also served on the executive committee of the CSC Toronto Chapter and various committees at the Toronto Construction Association including, the Membership Committee, the Entertainment Committee and the Young Construction Executives Club (now YCL).
