Signs You Need Interlock Releveling Ottawa
What Causes Interlock to Become Uneven
Pavers don't shift on their own—underlying issues create the movement:
Base Problems
- **Inadequate base depth** – Thin bases compress under load
- **Poor compaction** – Loose base material settles over time
- **Wrong base material** – Clay or organic soil doesn't provide stable support
- **Base erosion** – Water washes away supporting material
Water Issues
- **Drainage failure** – Water collects and softens the base
- **Downspout discharge** – Concentrated water flow erodes specific areas
- **Freeze-thaw heaving** – Ice expansion pushes pavers upward
- **Underground water** – High water tables destabilize bases
External Factors
- **Tree roots** – Growing roots lift pavers from below
- **Heavy loads** – Vehicles exceed design capacity
- **Adjacent construction** – Vibration and excavation affect stability
- **Age and settling** – Natural compaction over time
Trip Hazards and Drainage Issues Explained
Uneven interlock creates two serious problems:
Trip Hazards
- Height differences as small as 6mm cause trips
- Liability exposure for property owners
- Accessibility issues for elderly or mobility-impaired visitors
- Building code violations in commercial settings
Drainage Problems
- Low spots collect standing water
- Pooling accelerates freeze-thaw damage
- Mosquito breeding in warm months
- Ice patches in winter
- Water migration toward foundations
When Releveling vs Lift and Relay Is Needed
Understanding the difference saves you money:
Releveling (Minor Adjustment)
- Small areas of settlement
- Height differences under 25mm
- Base is generally sound
- Isolated problem spots
- Lower cost solution
Lift and Relay (Major Repair)
- Large areas affected
- Significant height differences (25mm+)
- Base failure evident
- Drainage problems throughout
- Multiple underlying issues
- More comprehensive but lasting fix
How Long Releveling Repairs Last
Properly executed releveling provides long-term results: **With proper base correction:** 10-15+ years **Surface-only adjustment:** 2-5 years Longevity depends on: We focus on permanent solutions, not temporary fixes.
Our Interlock Releveling Ottawa Process
We follow a proven process:
Survey and Diagnosis
Using levels and straightedges, we map the problem areas and identify what is causing the unevenness.
Paver Removal
Affected pavers are carefully lifted and set aside. We preserve pavers for reinstallation whenever possible.
Base Assessment
We examine the exposed base to determine if it needs repair, addition, or complete replacement.
Base Correction
Depending on findings: adding granular base material to low spots, compacting loose areas, improving drainage where needed, and replacing failed base sections.
Screeding
A fresh layer of bedding sand is applied and screeded to achieve perfect grade.
Paver Reinstallation
Original pavers are reset in their pattern, compacted, and joints are filled with polymeric sand.
