What is the best DIY kit to fix an expanding driveway fissu

[h=Hi everyone,

I am noticing a rather concerning development right down the center of our main concrete driveway where I park my heavy duty truck. A narrow, hairline fracture that appeared last summer has suddenly expanded into a deep, jagged gap that is now growing small weeds.

My neighbor suggested just pouring basic liquid caulk over it from the local hardware store, but I am worried that trapped water will freeze, expand, and completely shatter the entire pad this coming winter. Should I attempt an epoxy injection kit myself, or should I call a professional for proper Concrete Crack Repair.]2[/h]Thanks in advance.

You are 100% right to question your neighbor's advice on this one! Just pouring basic hardware store caulk over a deep, structural gap—especially under a heavy-duty truck—is like putting a band-aid on a broken bone. The weight of your truck will cause the concrete to flex slightly, and standard cheap caulk will tear right open, letting water seep underneath. When that trapped water hits Utah's winter freeze-thaw cycles, it will expand and turn that jagged gap into a massive, expensive pothole.
