Project Spotlight: Infill Preparation near Canada Avenue "We recently managed the site preparation for a new residential infill project just off Canada Avenue. Given the area's high water table, standard trenching wasn't enough. We installed specialized perimeter drainage and completed the sewer tie-in to strict City of Duncan municipal standards, ensuring the new foundation stays dry even during winter peak flows."

Q: My property is in the Cowichan River flood plain. Can you still excavate?

A: Yes, but it requires careful planning. We are familiar with the City of Duncan’s Flood Plain Management Bylaw (No. 3236) and the specific Flood Construction Levels (FCL) required to keep your home safe. We can work with your geotechnical engineer to prep the site correctly.

Q: Do you handle municipal water and sewer connections in Duncan?

A: Absolutely. Whether your property is within the City of Duncan or North Cowichan boundaries, we handle the full utility trenching and connection process. We coordinate with municipal inspectors to ensure the hookup passes inspection the first time.
