Interlock Repair

We are one of the select interlock repair and restoration companies in Ottawa.

Over the year’s interlock surfaces can become overtaken with weeds in their joints or uneven in areas due to our harsh winters in Ottawa.

As soon as uneven areas are noticed or weeds are creeping into joints, it is best to get it repaired as soon as possible.

As time goes on, water pools in lower uneven areas, causing more damage every year. We offer a few restoration options depending on your specific situation. Our services will give your old tired looking interlock an instant facelift!
