Why Concrete Cracks – JL Enterprise Denver, Colorado

Concrete cracking is one of the biggest concerns for homeowners and property managers in Denver, and the truth is simple: all concrete can crack — even when it’s done right. The trick is understanding why it happens and how to prevent the cracks that actually matter. Here’s the full breakdown from JL Enterprise, your local asphalt and concrete experts serving Denver and the surrounding cities.

Denver’s Climate: The Real Enemy of Concrete

Colorado has one of the harshest freeze–thaw cycles in the country. The ground expands, contracts, freezes, and thaws constantly. When the soil moves, the concrete sitting on top of it is forced to move too.

If the slab wasn’t installed correctly, that movement leads to cracking — sometimes fast, sometimes over years.

The 4 REAL Reasons Concrete Cracks

1. Poor Base Preparation

Concrete is only as strong as the base underneath it. If the soil isn’t compacted correctly, the slab settles unevenly — causing cracks, heaving, or sinking.

JL Enterprise always compacts the base properly to prevent this.

2. Insufficient Thickness

Cheap contractors often pour 3 inches to save money. At JL Enterprise, we pour 4 to 6 inches depending on the project size and load requirements.

Thicker concrete = stronger concrete.

3. No Reinforcement

Concrete is strong in compression but weak in tension.That’s why reinforcement matters.

JL Enterprise uses:

• Rebar

• Fiber mesh

• Proper joint spacing

This gives the concrete a backbone and reduces structural cracking.

4. Weather & Curing Conditions

Denver’s weather changes fast. Pouring concrete when it’s too hot, too cold, too windy, or curing it incorrectly leads to early cracking.

JL Enterprise schedules pours around weather windows and cures slabs properly every time.

When Cracks Are Normal (And When They’re Not)

Some cracks are completely normal — especially hairline cracks caused by natural shrinkage as concrete cures.

These do NOT affect the strength or lifespan of the slab.

Bad cracks include:

• Wide separation

• Vertical displacement

• Sinking or heaving

• Deep structural fractures

These are signs the slab wasn’t installed correctly — and that’s when you call JL Enterprise.
