About Michel Haydamous

Michel Haydamous

Michel Haydamous

Michel began his construction career as a management consultant. His experience in construction and bachelor’s degree in engineering brought him in contact with many construction companies, which is how he learned about the unique solutions for the basement environment and waterproofing provided by Basement Systems Inc.

This exposure inspired him to become part of the Basement Systems business, opening his own business as a certified dealer.He enjoys working with his team to help them create a healthier home for families in Quebec. Besides his work, Michel loves to spend time with his kids and wife and to read about history and scientific innovations.
