Overview
Concrete problems include cracks, surface flaking, and sunken sections. Some can be repaired, while others need replacement.
The cause, such as poor drainage or base failure, should be addressed or problems return.
What to expect, step by step
- Diagnose the cause. Drainage and base issues are common.
- Choose repair or replace. Severity decides.
- Work is done and cured. Repairs need cure time.
- Describe the area and use. Size, shape and what will sit on it, such as cars or a hot tub, shape the design.
- Site prep comes first. Excavation, compacted base and forms are a big part of a durable slab.
- Curing takes patience. Fresh concrete usually needs days before light use and longer before heavy loads.
Things worth considering
- Drainage needs a plan. Slabs should slope away from the house so water doesn't pool.
- Reinforcement varies. Ask whether rebar, wire mesh or fiber is included and why.
- Freeze-thaw cycles are hard on concrete. Proper air entrainment, sealing and drainage help in cold climates.
- Trip hazards matter. Sidewalk lips can create liability.
- Resurfacing has limits. Overlays need a sound base.
- Leveling may be an option. Sunken slabs can sometimes be lifted.
Before you send an inquiry
- Your address or nearest cross streets so the request reaches someone local.
- A short description of the job and where it is on the property.
- The best way and time to reach you.
- Rough measurements or quantities, if they matter for the job.
- Photos, if you have them; they help a provider understand the job faster.
Signs to slow down
- Door-to-door offers right after a storm with no local track record.
- No local address or references you can check.
- Unwilling to share proof of insurance or a license where one is required.
- Requests for large cash deposits before any work is scheduled.
- No written estimate, or an estimate with vague scope.
What to ask before you commit
- How will you handle control joints and slope for drainage?
- Is reinforcement included, and what type?
- What base material and thickness do you plan to use?
- Will you pull any required permits?
- What does your warranty cover for cracking or scaling?
- Is removal of the old concrete included?
People also ask
- Why is my concrete flaking?
- Freeze-thaw cycles and deicing salts are common causes.
- Can cracks be fixed?
- Many can be sealed or filled, but structural cracks need a closer look.
- Will my concrete crack?
- Most concrete develops some hairline cracks. Control joints, good base prep and proper curing help keep cracks where they're intended.
