Interlock Driveway Sinking, Cracking, or Overrun With Weeds? Here’s What GTA Homeowners Need to Know
After a long GTA winter, many homeowners step outside to find their interlock driveway looking worse for wear — sunken stones, weed-filled joints, crumbling edges, or a surface that’s just lost its original shine. The good news? In most cases, full replacement isn’t necessary. Professional repair and restoration can bring your interlock back to life at a fraction of the cost.
⚠ Spring 2026 heads-up for GTA homeowners
This past winter’s freeze-thaw cycles were particularly harsh. If your interlock has shifted, heaved, or developed new cracks since last fall, now is the time to act — small issues worsen quickly once spring rain sets in and weeds take root in open joints.
6 signs your interlock driveway needs professional attention
Don’t wait until the damage becomes a full replacement. These are the most common warning signs we see on GTA driveways every spring:
Sinking or uneven stones
Pavers that have shifted or dropped are a base failure issue — and a tripping hazard. The longer you wait, the more stones are affected.
Weeds growing through joints
Once polymeric sand breaks down, weeds colonize the gaps fast. They accelerate joint erosion and push stones apart over time.
Cracked or broken pavers
Individual cracked stones can be replaced without redoing the entire driveway — if caught early enough.
Water pooling on the surface
Poor drainage leads to freeze-thaw damage, mould growth, and an icy driveway in winter. Usually a grading or base issue.
Ant hills between stones
A classic sign that joints have eroded. Ants tunnel under pavers and weaken the base — don’t ignore this one.
Faded, dull colour
UV exposure and years of GTA winters strip the colour and finish from unsealed interlock. Restoration can bring it back to like-new condition.
Repair vs. full replacement: which do you actually need?
This is the most common question we get — and the honest answer is that most GTA driveways can be repaired, not replaced. Here’s a straightforward breakdown:
✓ Repair & restore (most cases)
- Localized sinking or shifting stones
- Weed-filled or eroded joints
- A few cracked or broken pavers
- Faded colour & loss of sealer
- Ant or drainage issues
- Driveway under 15–20 years old
- Structurally sound base
✕ Full replacement (rare)
- Complete base failure across entire driveway
- Majority of stones cracked or broken
- Severe drainage or grading issues
- Driveway over 25+ years old
- Extensive heaving throughout
- Original installation was severely poor
How our interlock repair process works
Every job starts with an honest assessment. Here’s what a professional restoration typically involves:
1
Inspection & assessment
We assess the base condition, drainage, joint integrity, and the extent of damage before recommending any work. No upselling — just an honest evaluation.
2
Pressure washing & debris removal
Industrial pressure washing clears all weeds, old sand, dirt, algae, and staining. This step is essential before any repair or sealing work begins.
3
Re-leveling & re-compacting
Sunken or shifted stones are lifted, the base is re-graded and re-compacted, and pavers are relaid level and tight. Broken stones are replaced to match.
4
Polymeric sand application
Fresh polymeric sand is packed into all joints. Once activated with water, it hardens to lock stones in place, prevent weeds, and block insects from nesting.
5
Sealing & finishing
A premium sealer is applied to protect against UV, salt, water, and freeze-thaw damage — and to restore that sharp, rich colour. Available in matte to high-gloss finishes.

Frequently asked questions
How much does interlock driveway repair cost in the GTA?
Costs vary based on the size of the driveway, extent of damage, and whether sealing is included. Minor repairs and re-sanding can start from a few hundred dollars, while full restoration of a larger driveway with sealing typically ranges from $800–$3,000+. We provide free, no-obligation quotes for every job.
How long does an interlock repair take?
Most residential interlock repair and restoration jobs in the GTA are completed in a single day. Larger driveways or jobs requiring full re-leveling of the base may take 2 days. Sealer needs 24–48 hours to fully cure before driving on it.
Can you match my existing interlock stones if some need replacing?
In most cases, yes. We work with all major suppliers including Unilock and Best Way Stone to source matching pavers. In cases where an exact match isn’t available, we can suggest complementary border designs that actually enhance the look of the driveway.
When is the best time to repair interlock in the GTA?
Spring through fall is ideal — specifically when temperatures are consistently above 5°C. May through October is our busiest season for good reason. That said, urgent repairs (safety hazards, severe drainage issues) can be assessed year-round.
