Avoid These 5 Common Concrete Mistakes (And What to Do Instead)

Don’t Let These Concrete Mistakes Cost You

Whether you’re pouring a driveway, patio, or sidewalk, avoiding common concrete errors is key to a long-lasting result. At Allentown PA Concrete, we believe a little knowledge goes a long way—so here’s what every homeowner should know.

Mistake #1: Pouring on the Wrong Subgrade

Why it’s a problem: Concrete is only as strong as the base it’s poured on. Soft, unstable, or uneven soil leads to future cracks.
What to do instead: Ensure proper compaction and use a gravel or crushed stone base to support the slab

Mistake #1: Pouring on the Wrong Subgrade

Why it’s a problem: Concrete is only as strong as the base it's poured on. Soft, unstable, or uneven soil leads to future cracks. What to do instead: Ensure proper compaction and use a gravel or crushed stone base to support the slab.

Mistake #2: Using Too Much Water in the Mix

Why it’s a problem: Excess water weakens the concrete and leads to scaling and cracking. What to do instead: Use just enough water to make the mix workable. A pro-grade mix will feel like thick oatmeal, not soup.

Mistake #3: Ignoring Joints and Expansion Gaps

Why it’s a problem: Without joints, concrete has nowhere to expand and will crack randomly.
What to do instead: Use control joints and expansion gaps in the right locations and spacing.

Mistake #4: Rushing the Finish

Why it’s a problem: Finishing too early (while bleed water is still present) traps moisture, leading to a flaky surface. What to do instead: Wait until the surface is matte and the bleed water evaporates before troweling or broom finishing.

Mistake #5: Not Curing Properly

Why it’s a problem: Concrete needs moisture to reach full strength. Poor curing results in weak, dusty, or cracked surfaces. What to do instead: Keep the surface moist for at least 7 days using wet burlap, plastic sheets, or a curing compound.
