It’s a yearly occurrence. One morning, you pull back the curtains, peek outside, and find your street buried under fresh snow. Snow season in Alberta doesn’t play around. It comes fast and hits hard.
If you own a business or commercial property in Calgary, you already know that it’s not the soft Christmas-movie snow here. It’s the kind of cold that comes with deep freezes, sudden melts, and unfortunate asphalt damage.
Your parking lot takes a beating every single winter. And if you’re not proactive about protecting it, you’ll be looking at major repairs come spring. Or worse, dealing with liability issues when someone slips and falls.
Here’s everything you need to know about winter-proofing your commercial parking lot. We’ll cover prep work, maintenance strategies, and how to minimize damage during Calgary’s harshest months.
Why Calgary Winters Are Especially Hard on Parking Lots
Let’s start with the obvious: Calgary’s climate is uniquely destructive to asphalt.
We don’t just get cold—we get chinooks. Those warm, dry winds melt everything, and then temperatures plummet again overnight. Water seeps into cracks, freezes, expands, and creates bigger cracks. This cycle repeats all winter long.
Add in the salt and sand we use for traction. These materials are necessary for safety, but they accelerate deterioration. Salt is particularly corrosive, as it breaks down the binding agents in asphalt.
The result? What starts as minor surface damage in November becomes a pothole nightmare by March.
Start With a Pre-Winter Inspection
You can’t protect what you don’t understand. Before the first snowfall, walk your entire parking lot. Better yet, have a professional assess it.
Look for existing damage like small cracks, areas where the surface is crumbling, and spots where water pools after rain. These problem areas will only get worse once winter hits.
Take photos and document everything. This gives you a baseline to work from.
If you find issues, address them now. Seal cracks before they fill with ice. Fix drainage problems before they become skating rinks. Patch potholes while the weather is still warm enough for repairs.
Waiting until spring means you’re letting damage compound for months. It’s like ignoring a small leak in your roof until the ceiling caves in.
Seal Coating: Your First Line of Defence
If your parking lot hasn’t been seal-coated recently, fall is the time to do it. Seal coating creates a protective barrier over your asphalt, almost like sunscreen for your parking lot.
The coating protects against water penetration, shields the surface from UV damage and oxidation, and makes the asphalt more resistant to salt and chemicals.
The catch is that you need to apply the seal coating before temperatures drop too low. The asphalt surface must be at least 10°C for proper application. In Calgary, that usually means getting the service done by late September or early October.
Seal coating doesn’t last forever. Most lots need reapplication every two to three years. But that’s a small price to pay compared to complete resurfacing.
Fix Drainage Issues Before They Freeze
Water is the enemy. If water can’t drain properly from your parking lot, you’re asking for trouble.
Standing water finds its way into cracks, where it freezes. Ice expands with tremendous force, and it can literally tear asphalt apart.
Check all your drains and catch basins before winter. Clear out debris. Make sure water flows away from the parking surface. If you have low spots where water pools, you might need to add drainage or regrade those areas.
Some property managers ignore drainage issues because they seem minor. Then winter arrives, and those minor issues become major headaches.
Snow Removal Strategy Matters
How you remove snow makes a huge difference in your parking lot’s longevity.
First rule: don’t wait. Remove snow as soon as possible after it falls. The longer the snow sits, the more likely it is to be compacted into ice. Compacted snow is harder to remove and more likely to cause damage.
Use the right equipment. Plow blades should have rubber or poly edges, not metal blades, which can gouge your asphalt surface. Set blade heights properly so you’re not scraping away at your parking lot with every pass.
Designate snow storage areas ahead of time. Don’t just pile snow anywhere. Keep it away from drains. Avoid creating massive piles that will take forever to melt in the spring.
Consider hiring professionals for snow removal. While it might cost more money, professionals who have the right equipment and experience are less likely to damage your lot while clearing it.
Smart Salt and Sand Application
You need traction, and your customers and employees need to walk and drive safely, but you also need to be strategic about how you use salt and sand.
Apply de-icing materials in moderation. More is not always better. Excessive salt accelerates asphalt deterioration without providing additional safety benefits.
Consider using calcium chloride instead of traditional rock salt in extreme cold. It works at lower temperatures and is slightly less corrosive.
Target high-traffic areas first. Focus on entrances, exits, walkways, and areas with slopes. You don’t need to salt every square inch of your parking lot.
Sand provides traction without the corrosive effects of salt. Use it in areas where you need grip but can tolerate some mess. Just remember you’ll need to sweep it up once temperatures rise.
When to Call the Professionals
Some property managers try to handle everything in-house. That’s fine for basic snow removal. But major winter preparation and repairs require expertise.
Professional paving companies understand Calgary’s specific climate challenges. They know which materials work best in our conditions and have specialized equipment for cold-weather repairs.
If you’re dealing with significant damage, drainage issues, or need seal coating, don’t go the DIY route. You might save more money upfront, but it’ll often cost you more in the long run.
A well-maintained parking lot is an investment in your property. It keeps customers and employees safe, projects professionalism, and saves you from costly emergency repairs.
Winter is coming. Your parking lot needs to be ready.
