June 2026 was Edmonton's wettest June on record. Here's what it did to your foundation.

If you live in the Edmonton area, you don't need us to tell you June was bad. You lived it.

The numbers still matter, though, because they explain what's happening under your house right now:

Streets flooded in Beaumont. A pedestrian bridge closed because the ground eroded under it. And thousands of basements across the region got wet, some for the first time ever.

If yours was one of them, this article is for you. And if yours stayed dry, keep reading anyway, because the second half is about you.

Where all that water went

Rain doesn't disappear when the sky clears. Around Edmonton, it soaks into clay soil, and clay is the worst possible material to have wrapped around your foundation.

Clay absorbs water and holds it. When it's saturated, three things happen against your basement walls:

1. Hydrostatic pressure builds. Saturated soil pushes water against your foundation with real force. Water under pressure finds every weak point: hairline cracks, the joint where your wall meets the floor, old tie holes, window wells.

2. Your weeping tile gets overwhelmed, or exposed as broken. Weeping tile is the drain pipe at the base of your foundation that carries groundwater away. In many older Edmonton homes it's clay tile that cracked or clogged decades ago. June was the stress test. If water came up along the wall-floor joint, your weeping tile likely failed it.

3. The clay swells, then shrinks. Saturated clay expands and presses on your walls. When it dries later this summer, it shrinks and pulls away. That movement widens existing cracks. Then winter's freeze-thaw cycles widen them again.

The damage from June 2026 hasn't finished showing up yet. Waterproofers get busy the spring after a wet year.

"My basement got wet in June. What now?"

First, sort out what actually happened, because the fix depends on it:

Sewer backup: water came up through floor drains, toilets or showers. That was the stormwater system failing, not your foundation. A backwater valve is the main protection here.

Overland flooding: water came in through window wells, doors or the top of the foundation because water pooled against the house. Grading, window well drains and downspout extensions are the front line.

Seepage: water came through the walls, through cracks, or up along the wall-floor joint. This is a foundation waterproofing problem, and it will repeat every time the soil saturates.

Here's the part most homeowners learn the hard way: insurance usually covers sudden events like sewer backup (if you have the endorsement), but not gradual seepage through the foundation. Seepage is considered a maintenance issue. The mold, ruined flooring and drywall that follow a slow leak are often yours to pay for. That makes fixing the entry point the only real protection you have.

Take photos of everything now, even if the water is gone. Water stains, efflorescence (the white chalky residue on concrete), damp carpet edges, rust at the bottom of steel posts. It documents the event, and it tells us where the water came in.

"My basement stayed dry. Am I fine?"

Maybe. But June 2026 was also a warning shot, and it's worth ten minutes to check:

• Look at the wall-floor joint in unfinished areas. Any damp line, white residue or musty smell means water reached the wall, even if it never pooled.
• Check foundation cracks outside. Anything you can slide a coin into is moving water when the soil saturates.
• Watch your window wells during the next rain. If they hold water, they're draining into your foundation, not away from it.
• Test your sump pump by lifting the float. June proved the systems around Edmonton can hit capacity. Your pump is the last line of defence, and if it's more than 8 to 10 years old, it's living on borrowed time.
• Extend your downspouts at least six feet from the house. It's the cheapest waterproofing that exists.

One more thing worth knowing: if your home was built in the last few decades, it was almost certainly damp-proofed, not waterproofed. Builders spray a thin coating that slows moisture but isn't designed to stop water under pressure, and it degrades over time. June put water under pressure against every foundation in the region. That's why plenty of newer homes leaked too.

Why acting before spring matters

The soil around Edmonton is carrying more water into fall than it has in decades. That water freezes. Ice expands roughly 9% and widens every crack it sits in. Then the spring melt sends it all back against your foundation at once.

A crack that wept a little in June becomes a leak next April. Summer and fall are also the best seasons for exterior work, because the ground is workable and we can excavate to the footing without fighting frost.

What to do next

Text a photo of what you're seeing to 780-910-6196. A crack, a damp corner, a stained wall, a window well. We can often tell you what you're dealing with the same day.

If it needs eyes on it, we come out, find where the water is getting in, and explain it in plain language. You get a written quote, free, no obligation. Sometimes the honest answer is a $400 crack injection, not a full excavation, and we'll tell you that too.

June 2026 already showed you where your house stands. The next system doesn't have to.
