Local context

Liberty Lake, WA

Representative project location: River District HOA near Pavillion Park.

  • Nearby landmarks
    Pavillion Park, Liberty Lake Regional Park, Trailhead Golf Course
  • Typical soil
    River District subdivisions frequently have engineered fill over silt — walkway settlement typically clusters near downspouts.
  • Drainage
    HOA-owned walkways commonly run adjacent to building downspouts and irrigation lines.
  • Freeze/thaw
    Liberty Lake's colder shoulder seasons produce longer freeze windows that heave joint edges gradually.

Project overview

What this project represents.

This case study represents a Liberty Lake HOA scope: nine trip hazards on association-owned walkways, identified during a board-directed insurance review, documented and repaired under a fixed scope with photo evidence.

The polyurethane foam approach delivered a board-friendly outcome: minimal resident disruption, per-hazard pricing, before/after documentation, and same-day return to service on every walkway.

The problem

What the homeowner was seeing.

  • Nine trip edges on HOA-owned walkways ranging from 1/2 to 1-1/8 inches.
  • Association insurance carrier had flagged the hazards during a routine inspection.
  • The board was weighing replacement (higher cost, longer disruption) against leveling for the annual maintenance budget.

Inspection findings

What the on-site walkthrough showed.

  • Board-approved walkthrough with the property manager — every hazard photographed, GPS-tagged, and measured.
  • Written scope with per-hazard pricing prepared for board approval.
  • Downspout, irrigation, and root proximity captured for each panel.

Cause of settlement

Why this slab moved.

  • Six hazards traced to downspout washout — repeated saturation of the walkway subgrade over 12+ years.
  • Two hazards traced to root uplift from association-planted parking lot island trees.
  • One hazard traced to differential settlement at a low spot in the walkway grading.

Repair solution

How the slab was lifted.

  1. 1Repairs scheduled across two working days, sequenced by walkway to minimize any single-area disruption.
  2. 2Each panel lifted with polyurethane foam under continuous laser monitoring.
  3. 3Every finished trip edge under 1/4 inch — within ADA guidance and consistent with the association's insurance carrier expectations.
  4. 4Board received a written project summary with before/after photos, elevation measurements, and maintenance recommendations for association records.

Why polyurethane foam was selected

The right tool for this project.

  • Board-friendly documentation — before/after photos and elevation data.
  • Per-hazard pricing gives the board a predictable annual maintenance budget line.
  • Same-day return to service on every walkway means residents aren't inconvenienced.
  • The cost of leveling all nine hazards was well below the cost of even a partial walkway replacement.

Repair timeline

Start to finish.

  • Scoping walkthrough

    Half-day with the property manager.

  • Board approval

    Written scope submitted for board vote — typical 2–4 week approval cycle.

  • Repair window

    Two working days across the site.

  • Documentation

    Final report with before/after photos delivered within one week of completion.

Estimated project size

Nine trip hazards across five walkways — approximately 180 sq ft of remedied concrete.

Expected lifespan

Polyurethane fill is stable long-term. With drainage corrections in place, additional trip-edge development from these locations is unlikely within the association's normal maintenance horizon.

Maintenance recommendations

How to make the repair last.

  • Add walkway trip-edge inspection to the annual HOA maintenance walk.
  • Extend building downspouts a minimum of 4 feet beyond walkway edges where feasible.
  • Reseal walkway joints every 3 years as part of the standard maintenance contract.

Frequently asked questions

Questions we hear on projects like this.

Do HOA boards usually approve leveling over replacement?
In our experience, once the cost differential and documentation quality is understood, most boards prefer leveling for common-area walkways where the concrete itself is still sound.
What documentation do you provide?
Before/after photos, per-hazard elevation measurements, and a written project summary suitable for association records and insurance carrier communication.
How do you handle resident notice?
The property manager typically distributes resident notice 48 hours in advance. Walkways are only closed during their individual injection window.
Can this be part of an annual maintenance contract?
Yes — many HOA clients use us on a rolling maintenance basis rather than a single project. See our HOA sidewalk repair page for the association-focused scope.
Is this ADA compliant?
Every finished trip edge measured under 1/4 inch, which meets ADA guidance for pedestrian surface transitions. See our ADA sidewalk compliance page for commercial specifications.
