Empty joints
Sand has washed or worn away, leaving visible gaps between pavers.
Interlock joint repair
Renew the Joints Between Your Pavers.
We remove failed material, clean the joint depth and install polymeric sand suited to the paver spacing and surface condition.
Repair-first recommendationsLocal Ottawa service
Joint material has a service life
Cracked or missing sand can be removed and replaced.
Polymeric sand helps lock the paver pattern together and reduces the space available for weeds and insects. It does not last forever.
A durable renewal depends on cleaning the joint to sufficient depth, choosing sand for the actual joint width and activating it according to the product requirements.
Ask about your repairWhat to look for
Signs this repair may be needed.
A visible change in the surface can point to a problem with support, restraint or drainage beneath it.
Cracked joint lines
Old polymeric material has separated and no longer bonds consistently.
Recurring weeds
Open joints collect organic matter and allow new growth to establish.
Loose pavers
The pattern lacks lateral support, though base movement must be ruled out first.
The repair process
Fix the problem in the right order.
Every repair begins with the condition beneath the surface—not with a coating or cosmetic shortcut.
- 01Check surface stability
Confirm that sinking or movement is repaired before renewing the joints.
- 02Remove failed material
Clean old sand, weeds and debris from the joints to the needed depth.
- 03Install the right sand
Select material for the joint width, paver type and expected exposure.
- 04Compact and activate
Fill the joints evenly and follow the proper water-activation sequence.
Joint width matters
The sand must match the size and condition of the joints.
Products designed for narrow joints may not perform the same way in large slab gaps or irregular stonework. Selection is part of the repair.

Common questions
Before you request a quote.
Send photos and a short description if you are unsure which repair applies.
How long does polymeric sand last?
Service life varies with installation, drainage, cleaning, traffic and weather exposure. Joint material should be inspected as part of regular maintenance.
Can new sand go over old sand?
Topping up shallow or failed joints usually does not create the depth needed for reliable bonding. Old material should be removed to the appropriate level first.
Will polymeric sand stop all weeds?
It reduces open space for growth, but airborne seeds and organic debris can still support weeds at the surface. Maintenance remains necessary.
Should sinking pavers be fixed first?
Yes. Joint repair cannot correct movement beneath the surface. Structural and drainage problems should be addressed before new sand is installed.
Keep the pavers. Fix the problem.
