Interlock Repair & Sealing
Don't tear it out. Most tired, sunken or weedy interlock can be lifted, fixed and sealed to look close to new, for a lot less than starting over.
One of the great things about interlock is that it can be fixed. Sunken sections, heaved edges, weedy joints and faded colour don't mean you need a new driveway or patio. Groundwork Landscaping lifts the problem areas, fixes the base underneath, re-lays the same pavers and finishes the surface so the whole area looks fresh.
What's included
- Lift and re-lay of sunken, heaved or shifted sections.
- Base repair, with new granular compacted under the low spots.
- Paver replacement of cracked or stained pieces, matched as closely as possible.
- Deep cleaning to lift dirt, moss, organic stains and old sand.
- Re-sanding of the joints with polymeric sand.
- Sealing with a natural or wet-look finish to deepen colour and protect the surface.
How a restoration runs
- Assess. We find what caused the problem, such as a downspout, poor base or roots.
- Repair. Problem sections lifted, the base fixed and the pavers re-laid level.
- Clean. The full surface cleaned and the old joint material flushed out.
- Sand and seal. Joints filled once dry, then the sealer applied.
Fix the cause, not just the surface
Sinking often comes from water. If a downspout is emptying onto the pavers, we'll redirect it as part of the job or with drainage work. If the interlock is beyond saving, we'll tell you, and quote a new patio or driveway instead.
What affects the cost of interlock repair & sealing
Repairs are priced on the area that needs lifting and re-laying, plus the area to clean, re-sand and seal. Deep sinking that needs more base, replacement pavers, moss and stain removal and the type of sealer affect the total. Restoring interlock almost always costs much less than replacing it.
Interlock Repair & Sealing questions
Can sunken interlock really be fixed?
Yes, in most cases. The pavers are lifted, the base is rebuilt and compacted, and the same pavers are re-laid level.
How often should interlock be sealed?
Every three to five years for most driveways and patios, depending on the sealer, sun and traffic.
Will sealing make my pavers slippery?
A good sealer, applied properly, adds very little slip. Wet-look finishes can be a little slicker, and we can add a grit additive where needed.
What's the white haze on my new pavers?
It's usually efflorescence, a natural salt that rises out of concrete. It fades on its own over time and can be cleaned off before sealing.
Will cleaning damage my joints?
Cleaning does wash out old sand, which is why we re-sand the joints with polymeric sand afterward.
Can you get rid of weeds between my pavers for good?
Re-sanding with polymeric sand makes it much harder for weeds to grow. No joint is weed-proof forever, but it cuts weeding way down.
Can you fix interlock around a sunken catch basin?
Yes. We lift the pavers around it, rebuild the base and reset them to the right height, and make sure water still flows into the drain.
Can I seal interlock myself?
You can, but surfaces need to be fully clean and dry, and joints set first. Uneven or cloudy sealer is hard to undo, so many people leave it to a pro.
