Calgary parging that lasts: fibre-mesh reinforced polymer-modified cement instead of the sand-cement mix that flakes off in two winters. Spot repairs, full resurfaces, crack filling and waterproofing. 5-year written warranty, same-day written quotes.
See Our Work ↓Calgary parging fails for predictable reasons: the freeze-thaw cycle, poor surface prep, or the wrong cement mix. Knowing which one is happening on your foundation is the first step to a fix that actually lasts.
Snow piles against the wall and the parging absorbs moisture. As temperatures swing overnight, water freezes and expands inside the cement, popping the face right off the foundation.
See What Goes Wrong → 02Parging applied over dusty, unprepared concrete has nothing to hold onto. It falls off in sheets within a couple winters. The fix is a real bond: fibre mesh in a polymer-modified base coat over a bonding agent, or galvanized mesh-lath pinned to the concrete when the wall calls for it.
Learn About Reinforcement → 03Standard sand-cement parging is brittle. When the foundation shifts even slightly with seasonal frost, rigid cement cracks. Polymer-modified mixes flex, which is why we don't use the cheaper standard mix.
See Why Polymer Matters →Spot repairs to crumbling, cracked, or spalling parging on residential foundations. We hammer-chip back to solid concrete, prep properly, and rebuild with fibre mesh in the base coat, or mesh-lath where the wall needs it.
When more than ~20% of the parging is failing, full resurface is the better long-term call. We strip back to bare concrete, embed fibre mesh in a polymer-modified base coat, and finish with a multi-coat system.
Hairline cracks, structural cracks, and spalled corners. We open the crack, address whatever's causing the movement, and rebuild with proper bonding agent and flexible polymer mix.
Alkali-resistant fibreglass mesh embedded in the polymer-modified base coat ties the parging into one continuous sheet, so cracks stop telegraphing through. Galvanized mesh-lath pinned to the concrete is available on request for badly spalled or previously failed walls.
Concrete retaining walls, garden walls, and any vertical concrete surface that needs a cosmetic coat or weather protection. Same polymer-modified system as foundation parging. For decorative stone facing over the same walls, see our stone masonry page.
Parging on new-build foundations before backfill or finished landscaping. We work with general contractors and homeowners on builder-grade and custom homes across Calgary.
Smooth Float, California Knockdown, or Rock Dash, we match the texture and grey tone of your existing parging so a spot repair blends instead of standing out as an obvious patch.
Crumbling parging is one of the most common Calgary home-inspection callouts. Fresh parging removes negotiation leverage and improves curb appeal, one of the highest-ROI fixes before listing.

Most parging that fails in Calgary fails because it was smeared on top of dusty, unprepared concrete with no mechanical anchoring. The new cement has nothing to hold onto. One winter of freeze-thaw and it sheets right off.
Our standard is fibre mesh: alkali-resistant fibreglass mesh embedded in a polymer-modified base coat over a bonding agent. It turns the parging into one reinforced sheet, so seasonal movement spreads across the wall instead of opening a crack.
Where a wall is badly spalled, has failed before, or a customer asks for it, we pin galvanized mesh-lath to the concrete first for a mechanical grip and parge through it. Both are options on every quote, and we tell you which one the wall needs.
Standard sand-and-cement parging is rigid. When your foundation shifts even fractionally with frost movement, and every Calgary foundation does, rigid cement has no give. Hairline cracks open up the first winter. Water gets behind. The cycle starts.
Polymer-modified parging is fortified with acrylic additives that act like a built-in glue. Stronger bond to the wall, and the cured cement keeps a small amount of flexibility so it can absorb seasonal movement instead of cracking through it.
Cementitious parging is the traditional coat: Portland cement and sand troweled over the exposed foundation, sometimes with lime for workability. It is what most Calgary homes built before the 2000s have on them. Done well over clean, damp concrete it is hard, breathable and cheap to repair. It is also rigid, so it cracks when the foundation moves with frost, and it flakes off when it was smeared over dusty concrete with no bond.
Acrylic parging is a polymer-modified or acrylic-based finish coat. The acrylic resin gives the cured coat some flex and a much stronger grip on the wall, and it can be tinted and textured to match the stucco above it. It is the better call on foundations that have already cracked and been patched, on ICF foam that needs a coat with real adhesion, and anywhere the parging has to meet an acrylic stucco wall cleanly. A pure acrylic finish still needs a cementitious base coat under it: it is a finish, not a structural coat.
What we use: a polymer-modified cementitious mix on every foundation. Cement for the strength and breathability, acrylic polymer for the bond and the flex. With fibre mesh in the base coat it lasts 15 to 25 years in Calgary where a plain sand-cement coat lasts two to five. Where a customer wants a tinted acrylic finish for the look, it goes on top of that base, never straight onto concrete.
Two decades of foundation work has shown us the same handful of patterns over and over. If you're noticing any of these, the underlying problem is rarely the parging itself. It is how it was installed or what's happening around it.
Snow piled against the foundation all winter saturates the bottom of the parging. Repeated freeze-thaw at the grade line causes spalling. Keep snow at least a foot off the wall.
Parging applied over dust, paint, or old failing parging has no bond. We pressure-wash, hammer-chip, and prime with bonding agent before any cement goes on the wall.
Cheap mixes with no polymer modification crack with the first frost movement. We don't quote standard sand-cement parging, it never lasts in Calgary's climate.
If the ground slopes toward the house, every rain drains down behind the parging. The cement skin looks fine while the wall behind it stays wet. Re-grading often has to come before any parging fix.
Homeowner patches over visible damage often seal moisture in rather than fixing the source. The original problem grows behind the patch and surfaces somewhere new the next year.
White powdery deposits on the parging mean water is moving through the cement and depositing minerals on the surface. The parging is doing its job, but there's a moisture source to find.
Most parging in Calgary fails within 2–5 years. Not because parging is fragile, but because contractors use the cheapest sand-cement mix on the cheapest prep. Cement cracks, no bond, water gets behind, the cycle starts.
We use polymer-modified parging for every foundation we touch. The polymer acts as a built-in adhesive and gives the cured cement the small amount of flexibility it needs to handle Calgary's 30+ °C daily summer-to-winter swings without cracking.

Parging is the visible coat. Under it, the concrete has to be sealed. These are the three jobs that keep water out of a Calgary foundation before the finish goes on.
Foundation cracks are opened with a grinder to a clean V, blown out, and filled. Hairline shrinkage cracks get a polymer-modified or hydraulic cement fill. Cracks that leak get polyurethane injection from the inside so the fill follows the crack through the wall. Then the parging is rebuilt over the repair so it disappears.
Crystalline waterproofing is a cement-based slurry brushed onto damp concrete. Its chemicals react with the moisture and lime in the concrete and grow crystals into the pores and hairline cracks, blocking water from inside the concrete itself. It cannot peel like a membrane and it keeps working when new hairlines open. We use it on leaking foundation walls, cold joints and around penetrations before parging.
Above grade, an elastomeric or acrylic waterproofing coat over the parging sheds rain and snowmelt and stays flexible through freeze-thaw. Below grade on an exposed wall, a rubberized damp-proof coating, and where the wall is dug out, a drainage membrane. The right coat depends on whether the wall is wet from outside or damp from inside, and we tell you which on the visit.

ICF foam above grade cannot stay bare, UV breaks it down and code requires a protective coat. That coat is parging: fibre mesh embedded in polymer-modified cement, and it is the one scope every ICF build in Calgary must buy. We schedule it to your pour calendar, quote it per lot, and keep it consistent house to house. Building the whole envelope? One sub covers stucco, stone and parging in a single mobilization.

On most Calgary homes the stucco wall ends where the parged foundation begins, and the two fail together. Cracks travel across the transition line and water tracks behind both materials. We repair stucco and parging as one system, matched in colour and texture where they meet, so the fix disappears. See our stucco repair work →

Practical answers to the questions Calgary homeowners ask before hiring a parging contractor.
These are rough estimates only, not a quote. Parging is priced after we see the foundation, because how much old parging has to come off, the length of wall, corners and steps, the texture, and whether the concrete under it needs crack filling all change the number. As a very rough guide only: a spot patch or one side of the foundation tends to land somewhere around $300 to $1,300 and up. One or two walls up to a full foundation resurface with fibre mesh, around $1,400 to $5,000 and up. Crack filling, crystalline waterproofing and other foundation work on top of the parging can take a job to $10,000 and beyond. All figures before GST, and a real job can land outside these ranges. The free on-site visit and written quote is the number to plan around.
Parging is the cement coating on the exposed portion of your foundation wall, the strip of concrete visible between your siding or stucco and the ground. It protects the foundation from water infiltration, hides raw concrete, and gives the house a finished look. In Calgary it takes a beating from freeze-thaw, road salt, and snow contact.
We generally recommend repair if the damage is limited to spot areas, usually 20% of the surface or less. Anything more extensive, full resurface is the better long-term call. Every foundation is different though, the only honest way to know is to have us come look. Free assessment.
Three common causes in Calgary: (1) the previous contractor applied parging over dusty, unprepared concrete, no bond; (2) standard sand-cement mix was used instead of polymer-modified parging, so it cracks with thermal movement; (3) water is entering behind the parging from a grading issue. We diagnose the root cause before quoting, no band-aid fixes.
Properly installed parging with polymer-modified cement and fibre mesh reinforcement should last 15–25 years in Calgary. Poorly installed parging, over dusty concrete, standard sand mix, often fails in 2–5 years. Our parging carries a 5-year workmanship warranty.
Not reliably for full repairs. Parging cement needs temperatures above 5°C for at least 48 hours to cure properly. Calgary parging season runs roughly April through October. Emergency spot patches can be done year-round with cold-weather rated products if you have an active water issue.
Crumbling or missing parging is one of the most common Calgary home-inspection callouts. Buyers often assume foundation problems even when there are none. Fresh parging dramatically improves curb appeal and removes negotiation leverage. It's one of the highest-ROI cosmetic exterior fixes before listing.
Parging is a thin cement coating on foundation concrete, typically the strip between siding and grade. Stucco is the wall finish on the rest of the exterior, usually applied over wire lath or EIFS foam. Both are cement-based but use different mixes and serve different purposes. We do both, and we make sure the transition between parging and stucco at the top of the foundation is properly sealed.
Yes, we match texture (Smooth Float, California, or Rock Dash) and grey tone for spot repairs. On older sun-faded parging a perfect colour match isn't always possible. When that's the case we'll tell you upfront and recommend either a wider re-coat for uniformity or accept a slightly visible patch.
Three main Calgary styles: Smooth Float (clean modern sponge finish, new builds), California / Knockdown (textured trowel finish, most common Calgary parging), and Rock Dash (embedded aggregate, traditional older homes). We match your existing finish or recommend the best option for new installs.
Yes. We parge concrete retaining walls, garden walls, garage foundations, and any vertical concrete surface that needs a cosmetic coat or weather protection. Same polymer-modified mix and fibre mesh system as foundation parging.
Yes, and on a foundation that has been leaking we will not parge over it until that is done. Cracks are ground out and filled, or injected with polyurethane from the inside if they leak. Damp or leaking walls get a crystalline waterproofing slurry that seals the concrete from within, and above grade we can add an elastomeric waterproofing coat over the finished parging. The parging is then rebuilt over all of it so the repair does not show.
A cement-based slurry brushed onto damp concrete. It reacts with the moisture and lime in the concrete and grows crystals into the pores and hairline cracks, so the concrete itself stops passing water. It is not a membrane, so it cannot peel, and it reactivates if water reaches a new hairline later. We use it on leaking foundation walls, cold joints and around pipe penetrations before the parging goes on.
