Signs You Need Interlock Releveling Ottawa

Inadequate base depth – Thin bases compress under load
Poor compaction – Loose base material settles over time
Drainage failure – Water collects and softens the base
Downspout discharge – Concentrated water flow erodes specific areas
Freeze-thaw heaving – Ice expansion pushes pavers upward
Tree roots – Growing roots lift pavers from below
Heavy loads – Vehicles exceed design capacity

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:

1

Survey and Diagnosis

Using levels and straightedges, we map the problem areas and identify what is causing the unevenness.

2

Paver Removal

Affected pavers are carefully lifted and set aside. We preserve pavers for reinstallation whenever possible.

3

Base Assessment

We examine the exposed base to determine if it needs repair, addition, or complete replacement.

4

Base Correction

Depending on findings: adding granular base material to low spots, compacting loose areas, improving drainage where needed, and replacing failed base sections.

5

Screeding

A fresh layer of bedding sand is applied and screeded to achieve perfect grade.

6

Paver Reinstallation

Original pavers are reset in their pattern, compacted, and joints are filled with polymeric sand.
