Common Concrete Mistakes Homeowners Make (And How to Avoid Them)

Concrete is one of the most durable materials you can use around your home—but only when it’s done correctly. Unfortunately, we often see homeowners dealing with cracking, settling, and premature failure because of avoidable mistakes made early in the process.

At Wally’s Concrete, many of our repair calls start with the same phrase: “I wish I had done this differently.” Here are the most common concrete mistakes homeowners make—and how to avoid them.

Mistake #1: Skipping Proper Base Preparation

This is the number one cause of concrete failure.

Without proper excavation and compaction:

• Slabs settle

• Cracks form quickly

• Surfaces become uneven

Concrete relies on a stable base—especially in Denver’s freeze-thaw climate.

How to avoid it:
Always insist on proper base prep with compacted gravel or road base.

Mistake #2: Choosing the Lowest Bid

Cheaper concrete often means corners were cut.

Low bids may skip:

• Reinforcement

• Proper thickness

• Correct concrete mix

• Drainage planning

Short-term savings often lead to long-term repair costs.

How to avoid it:
Choose a contractor based on experience, not just price.

Mistake #3: Poor Drainage Planning

Concrete that traps water will fail faster.

Common drainage issues include:

• Pooling water

• Ice buildup in winter

• Erosion beneath slabs

How to avoid it:
Ensure slabs are properly sloped and water drains away from structures.

Mistake #4: Improper Reinforcement

Reinforcement is critical—but only if installed correctly.

Problems occur when:

• Rebar is missing or improperly spaced

• Wire mesh sinks to the bottom

• Reinforcement isn’t secured

How to avoid it:
Confirm reinforcement is part of the project plan—not an afterthought.

Mistake #5: Pouring at the Wrong Time of Year

Colorado weather can ruin concrete if timing is off.

Pouring during:

• Extreme heat

• Freezing conditions

• Sudden weather swings

can weaken concrete significantly.

How to avoid it:
Work with a contractor who understands local weather patterns.

Mistake #6: Rushing the Curing Process

Concrete needs time to cure properly.

Rushing leads to:

• Surface cracking

• Reduced strength

• Shortened lifespan

How to avoid it:
Allow adequate curing time and follow professional recommendations.

Mistake #7: Ignoring Early Warning Signs

Small cracks and surface issues rarely fix themselves.

Ignoring early signs leads to:

• Larger cracks

• Structural issues

• Costly replacement

How to avoid it:
Address minor problems early with professional repairs.

DIY vs. Professional Installation

DIY concrete projects often struggle with:

• Proper prep

• Weather timing

• Finishing quality

• Long-term durability

Professional installation costs more upfront—but saves money over time.
