Willem Ligthart began his career in construction in the Netherlands in 1998, eventually bringing his skills and dedicated work ethic to Canada in 2011. Today, he and his team continue to bring increasing value and quality craftmanship to Southwestern Ontario and beyond, as Dordt Contractors Inc. and Dordt Waterproof Solutions.


Our team is dedicated to delivering satisfaction and value to our customers. Dordt Contractors brings high quality products and skilled labour to every project, specifically in the areas of general contracting, renovations, flat roofing and septic design and installation.


Dordt Waterproof Solutions offers cutting edge technology to meet the growing demand for water storage systems. As an importer of the acclaimed Dutch fabricating Company Genap, we are proud to bring leading waterproof solutions to North America and beyond, maintaining the same quality service customers expect from the Dordt name.



We are open, reliable and honest in our relationships with clients, colleagues, subcontractors, suppliers and partners. It is important that we foster an environment that encourages workers to be consistent, cooperate as a team, and accept responsibility.

We are also realistic. No matter how spectacular a project may be, we are committed to working hard and being straightforward. This empowers us to deliver projects on schedule, within budget. We value integrity and actions that build trust.



We do not compromise quality in any of our divisions. Our commitment to quality is reflected in our people, processes and materials.


We are committed to providing a safe workplace for our customers, workers and other stakeholders. We believe that all workers have the right to work in a safe and healthy work environment.



We can only be successful by working effectively within our teams. We seek and achieve the best solutions for our customers, as well as with clients, partners, subcontractors, suppliers and colleagues. We respect each other and act accordingly.


We love our profession and we love a challenge. Passion for what we do gives us the energy to push boundaries.
