Adam and Zack Askew founded A&Z Interlock Design & Build back in 2005, building decks and patios across the Ottawa area.
After more than 20 years in outdoor construction, they recognized a gap in the industry: Ottawa homeowners didn't have a single company that could handle both the foundation and the build. Most had to coordinate between a pile installer and a separate contractor — adding cost, delays, and finger-pointing.
So they expanded into helical pile installation, earned CCMC certification, and partnered with Almita — the leading manufacturer of engineered helical piles in Canada. They also brought on consultants with over 40 years of foundation experience.
Today, A&Z is the only Ottawa company that handles everything: foundation to finish. One crew. One point of contact. One company accountable from the first pile to the final board.
Adam brings 20+ years of experience in outdoor construction and helical pile foundations. He works closely with the installation crew and ensures quality standards are met on every project.
Zack manages client relationships, scheduling, and project coordination. He makes sure every client gets a smooth experience from the initial quote through final completion.
