Frequently asked questions
When can interlock be installed in Ottawa?
Typically from spring through fall when the ground is not frozen. Book early in the season for the best choice of dates.
How do you prevent sinking and shifting?
With proper excavation depth, a well-compacted base, edge restraint and drainage planning, which matter more than the stone itself.
Do I need a permit for an interlock driveway?
It depends on changes to the driveway width, curb cuts or grading. We check City of Ottawa rules for your property.
Can you fix my existing interlock?
Yes. We can lift, rebuild the base and relay sunken or uneven areas, and refresh the joints.
