So, What the Heck is Spray Patching?

One minute you're cruising with your iced coffee and the next WHAM, your suspension is filing for early retirement and your latte's in your lap. But fear not: there’s a superhero in the road maintenance world, and its name is Spray Patching. It might not wear a cape, but it does blast aggregate and emulsion at high speed into craters like it’s starring in Fast & the Furious: Municipal Budget Edition!

Let’s be honest—when most people hear “spray patching,” their eyes glaze over faster than a pothole fills with rainwater. But if you’ve ever hit a crater in the road and felt your soul—and your suspension—leave your body, then you might want to keep reading. Because spray patching isn’t just another repair method; it’s the secret weapon in the eternal war on potholes.

Okay, but what is spray patching?

Spray injection patching (a.k.a. “spray patching”) is a high-efficiency method of repairing road defects. A specialized truck uses compressed air to blast debris out of a pothole, sprays in a tack coat of emulsion, adds aggregate, then seals the whole thing into a homogenous, sealed end product filling the pothole or defect. No hot mix, no expensive paving equipment, and no long traffic closures!

But does it actually work?

Let’s look at the data. According to a multi-year performance study by the Minnesota Department of Transportation (MnDOT) a leader in spray patching research, spray patching held a 92% success rate after one year, far outlasting the traditional “throw-and-go” method

MnDOT also found:

• Spray-patched potholes lasted 4+ years on rural highways. That’s longer than most gym memberships!

• It costs 70-90% LESS than mill and fill or full paving programs, making it one of the most cost-effective and durable maintenance methods on the market. This makes it ideal for preventative and spot repairs, keeping good roads good longer and stretching capital budgets.

• It dramatically reduces lane closures and improves the commuter experience, which is always a win.

Think of it like road Tupperware.

Spray patching doesn’t just slap material on top. It seals the pothole from the inside out, locking in dry, clean aggregate with emulsion that clings like your toddler during school drop-off. The result is a tight, water-resistant patch that holds up to weather, traffic, and even winter in Alberta.

• Fast (most patches take minutes),

• Efficient (1 truck, 1 operator, 1 raker),

• Sustainable (minimal waste, fewer re-dos),

• Cost Effective (stretching capital budgets to prolong road use)
