For BC Strata Councils & Property Managers
A Property Manager's Guide to Strata Concrete Maintenance
Quick Answer
Shared concrete — parkades, walkways, entry aprons, and common-area patios — is one of the largest physical assets your strata owns, and it degrades quietly under Okanagan freeze-thaw cycles and tracked-in road salt. A scheduled re-seal cycle is preventive maintenance that protects the contingency reserve fund and helps a strata avoid the special levy that comes with an emergency repair. This guide walks councils and property managers through how to inventory those surfaces, fit the work into the depreciation report, budget it honestly, and vet a contractor.
The Okanagan Problem
Why Shared Concrete Fails Here
Okanagan concrete takes a beating that mild coastal climates never see. Understanding how it fails is the first step to budgeting for it, because the damage is almost always cheaper to prevent than to repair.
Freeze-thaw cycles
The Okanagan runs through 50–80+ freeze-thaw cycles a year. Water seeps into the concrete's pores, freezes, expands, and forces the surface apart. Over enough winters that shows up as scaling and spalling — the surface flaking and crumbling away. Every cycle is a small crack-growing event, and shared surfaces see it across thousands of square feet at once.
De-icing salt
Road salt and de-icers tracked into parkades and spread on walkways accelerate the damage. Salt pulls moisture in, worsens the freeze-thaw cycle, and chemically attacks the concrete. In a parkade, salty meltwater dripping off vehicles is one of the most aggressive things a slab faces.
Water reaching rebar
Parkade decks and elevated slabs are reinforced with steel. Once water and chloride from salt penetrate to that rebar, it corrodes and expands, cracking the concrete from the inside out. This is the failure mode that turns a maintenance line item into a structural repair — and a structural parkade repair is exactly the kind of bill that triggers a special levy.
Trip and liability risk
Scaling and spalling on walkways and entry aprons isn't just cosmetic. Lifted, crumbling, or uneven shared concrete is a trip hazard, and a fall on common property is the kind of incident that becomes a liability claim against the strata. Keeping shared walking surfaces sound is a safety obligation, not just an aesthetic one.
Where It Fits
Concrete Maintenance and BC Strata Governance
Concrete upkeep isn't a side issue for a strata — it sits right in the middle of the tools BC strata corporations already use to plan for the future. Here's how the pieces connect. None of this is legal advice; check your own bylaws and lean on your strata manager and depreciation report provider for the specifics that apply to your corporation.
The depreciation report
A depreciation report is the strata's long-range look at its common assets — what they are, what condition they're in, and roughly when each will need major repair or replacement, with the funding to match. Shared concrete is a textbook asset to include: it has a long but finite life, it degrades on a predictable curve, and proactive sealing extends that life. When concrete upkeep is documented in the report — condition, re-seal cycle, expected repairs — council and owners can plan for it instead of being blindsided.
The contingency reserve fund (CRF)
The CRF is the strata's savings account for common-asset repair and replacement. A planned, recurring re-seal cycle is the kind of steady, foreseeable expense the CRF exists to smooth out. Funding maintenance from the reserve keeps costs predictable and spreads them fairly across owners over time — far better than the alternative below.
Strata Property Act expectations
BC strata corporations carry a general duty to repair and maintain common property. Speaking broadly, that responsibility points toward proactive care of shared assets like concrete rather than letting them fail. A documented maintenance program is the clearest evidence a council is meeting that duty in good faith. For the exact obligations and any votes or approvals required, confirm with your strata manager — bylaws and circumstances vary.
Scheduled maintenance vs. the special levy
This is the heart of the case. A maintained re-seal cycle is a modest, predictable line item funded steadily through the CRF. An emergency parkade or walkway repair after years of neglect is a large, sudden bill — and when the reserve can't cover it, that gap is closed with a special levy charged to every owner. Owners remember special levies. Prevention is almost always the cheaper, calmer path, and it's an easier story to tell at an AGM.
The Framework
A Practical Maintenance Framework
1. Inventory your shared concrete. Walk the property and list every common concrete surface: parkade decks and ramps, shared walkways, entry aprons, common-area patios, stairs, and loading or service areas. Note the approximate square footage and current condition of each. You can't plan or budget what you haven't catalogued.
2. Set a re-seal cycle by surface. Different surfaces wear at different rates — the simple rule is more traffic means more frequent attention. A parkade deck carrying vehicle weight and salty meltwater needs care sooner than a quiet courtyard patio. A pedestrian walkway sits in between. Condition-based timing beats a blanket calendar number.
3. Demand a real vendor scope. A good assessment should cover surface-by-surface condition, measured areas, the prep required (cleaning, crack treatment, stripping any failed old coating), the product proposed for each surface, and the expected protection life. Vague, one-line quotes are a red flag.
4. Document it for the depreciation report. Feed the inventory, condition notes, re-seal cycle, and cost ranges into your depreciation report and CRF planning. That paper trail is what turns "we should probably seal the parkade" into a funded, defensible program council can stand behind.
Traffic drives the schedule
Parkade decks and ramps wear fastest, walkways and aprons sit in the middle, and quiet common patios wear slowest. Build your re-seal cycle around how hard each surface actually works — not a single number for the whole property.
Budgeting
What to Budget — and What Moves the Number
Strata concrete is priced by the job, not from a sticker. Anyone who quotes a parkade over the phone is guessing. These are the factors that actually set the number — a free on-site assessment turns them into itemized figures you can take to council.
Total surface area
The biggest lever. Sealing is largely priced per square foot, so the combined area of your parkade, walkways, and patios is the foundation of any budget. Larger stratas with multiple buildings carry more square footage and more scheduling complexity.
Condition & prep
Clean, sound concrete seals quickly. Heavy salt scaling, oil staining, moss, cracks, or a failed old coating that has to be stripped first all add prep labour before any sealer goes down. The worse the starting condition, the more the prep weighs on the number.
Surface type & access
Traffic decks, ramps, stairs, and tight or gated areas take more care and time than open flatwork. Phasing the work to keep residents moving — staging by level or zone — is the right call, and it factors into scheduling and cost.
The honest comparison to keep in front of council: sealing is a fraction of replacement. Replacing failed concrete runs many times the cost of maintaining it, before you factor in resident disruption and the special levy that funds an emergency repair. A maintained re-seal cycle isn't an expense — it's reserve-fund protection.
Due Diligence
How to Vet a Concrete Contractor
Common-area work on strata property deserves the same diligence as any other vendor going through council. Before you award the job, confirm:
- WorkSafeBC coverage — ask for a current clearance letter so the strata isn't exposed if a worker is injured on common property.
- Proof of insurance — a certificate of insurance (COI) naming appropriate coverage, available on request.
- The right product for the surface — a traffic-deck sealer for parkades is a different decision than flatwork; the vendor should match product to use.
- A scope you can read — measured areas, prep, product, and protection life in writing, not a one-line price.
- References and a willingness to assess on site before quoting.
OKGN is licensed and insured, WorkSafeBC-covered, and can provide a COI and clearance letter on request — the basics a council should expect from anyone working on common property.
The Product
Penetrating Sealers vs. Surface Coatings
For high-traffic strata surfaces, the product class matters. Cheap topical coatings sit on top of the slab and peel under vehicle traffic and freeze-thaw — they look fine for a season, then flake and need stripping.
We use Pavix CCC-100, a penetrating dual-crystalline sealer that soaks into the concrete and becomes part of the slab rather than forming a film on top. It's a penetrating treatment — not a membrane — which means there's no surface coating to peel off under tire abrasion. For parkade decks and other traffic surfaces, that's the difference between a one-time treatment and a coating you keep redoing.
For the full breakdown on traffic-deck protection, see our parkade sealing page. For broader plaza, storefront, and multi-surface commercial work, see commercial concrete sealing.
Why It Suits Strata Surfaces
- Penetrates the slab instead of forming a film — nothing to peel under vehicle traffic.
- Built to fight the freeze-thaw and salt damage that drives Okanagan parkade failure.
- Long protection life means fewer re-applications across the maintenance cycle.
- Lower cost-per-year than coatings you strip and redo every couple of seasons.
FAQ
Strata Concrete Maintenance: Common Questions
How often should strata concrete be re-sealed?
There's no single number — it depends on the surface and the traffic it carries. As a planning rule of thumb, high-traffic parkade decks that take vehicle weight, tire abrasion, and tracked-in road salt need attention more often than a quiet common-area patio. Penetrating sealers protect for far longer than the cheap topical coatings that peel every couple of years. The honest answer for any strata is to put each surface on a documented inspection cycle and let condition — not a calendar guess — trigger the re-seal. A site assessment gives you a realistic schedule per surface.
Does concrete maintenance belong in the depreciation report?
Yes. Shared concrete is a common asset that wears out and eventually needs major repair or replacement, which is exactly the kind of item a depreciation report is meant to anticipate. Scheduled sealing and preventive upkeep is the cheaper end of that lifecycle — documenting it (and the re-seal cycle that extends asset life) gives your depreciation report provider and council a clearer, more defensible picture than treating concrete as a surprise emergency every decade.
Is sealing cheaper than repairing or replacing concrete?
Almost always, over the life of the asset. Sealing is preventive — it slows the freeze-thaw and salt damage that causes scaling, spalling, and rebar corrosion. Repair and replacement are reactive, far more expensive per square foot, and disruptive to residents. A maintained re-seal cycle funded through the contingency reserve fund is steady and predictable; an emergency parkade repair is the kind of bill that ends up funded by a special levy.
How do you seal common areas without disrupting residents?
Scheduling and phasing. Parkade and walkway work can be staged by zone or level so residents always keep a usable route in and out. We confirm access, cure times, and any temporary closures in writing before the job starts, and coordinate timing with the property manager around resident notice requirements. The goal is a quiet, predictable job — not a building-wide shutdown.
Who is responsible for common-area concrete — the strata or the owner?
Generally, common property is the strata corporation's responsibility to maintain, while limited common property and an owner's own lot may fall differently depending on the strata's bylaws and how the surface is designated. Parkades, shared walkways, entry aprons, and common patios are typically strata-maintained common assets. Because designations vary by strata plan and bylaw, council should confirm what's classed as common property before scoping work — but the shared concrete that affects everyone usually sits squarely with the strata.
How do I get council approval for a concrete maintenance program?
Bring evidence, not vibes. A documented condition assessment of each surface, a clear scope, planning-stage cost ranges, and the lifecycle case (maintained re-seal cycle versus a future special levy for emergency repair) give council and owners something concrete to vote on. Tying the program to the depreciation report and funding it through the contingency reserve fund frames it as responsible asset management rather than discretionary spending. We can provide an itemized site assessment you can take straight to a council meeting.
