Correct the cause beneath the pavers

A Stronger Foundation for the Interlock You Own.

We identify why the surface moved, rebuild the failed support and relay reusable pavers over a properly prepared base.

Long-term support

The repair is only as strong as the base below it.

Base depth, aggregate selection, compaction, grading and edge support all influence how an interlock surface performs through Ottawa freeze-and-thaw cycles.

Foundation repair makes it possible to correct the failed area while preserving pavers that remain in good condition.

What 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.

01

Repeated settlement

A section sinks again after a surface-only levelling attempt.

02

Widespread movement

Several pavers rotate, spread or change elevation together.

03

Soft outside edges

The perimeter moves because the base or restraint no longer holds it.

04

Poor drainage

Water enters or washes through the supporting layers beneath the pavers.

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.

  1. 01
    Assess the base failure

    Review settlement, drainage, grade, edge support and the affected footprint.

  2. 02
    Lift reusable material

    Remove and organize sound pavers so the original surface can be rebuilt.

  3. 03
    Excavate and rebuild

    Replace weak material and compact the repaired foundation in controlled layers.

  4. 04
    Restore the surface

    Relay the pavers, confirm the grade and complete the joints and edges.

Foundation before finish

A permanent repair begins below grade.

Cosmetic work cannot compensate for missing depth, loose aggregate or an unstable edge. The supporting structure must be corrected first.

Common questions

Before you request a quote.

Send photos and a short description if you are unsure which repair applies.

How do you know the base has failed?

The pattern and extent of movement provide clues, but the exact condition becomes clear after affected pavers are lifted and the supporting layers can be inspected.

Can the existing pavers go back down?

Yes, when the pavers are sound. Reusing them preserves the existing pattern and keeps the repair focused on the failed support.

Does every low spot require a full rebuild?

No. The repair footprint should follow the actual failure. A stable surrounding area may not need to be disturbed.

Can drainage be corrected at the same time?

When water movement contributed to the failure, drainage and grade should be addressed as part of the foundation repair.

Keep the pavers. Fix the problem.
