What Causes Concrete to Crack?
Before you can prevent it, you have to know what causes it. The most common reasons include:
- Shrinkage – Concrete shrinks slightly as it dries. Without the right joints or moisture control, this leads to surface cracks.
- Soil movement – Expansive soil or erosion under a slab can shift, causing pressure and cracking.
- Poor base prep – If the ground beneath concrete isn’t compacted properly, it can settle unevenly.
- Extreme heat or cold – In hot places like San Diego, high heat can cause rapid drying and surface cracks.
- Heavy loads – Concrete not designed for traffic can crack under cars, dumpsters, or other weight.
All of these issues can lead to concrete cracks, both small and large across driveways, patios, foundations, and walls.
The Cost of Letting Concrete Cracks Go Unfixed
Most concrete projects in Alpine range from $2,500 +, leave it long enough and it will get worse. Here’s what can happen:
- Water intrusion – Cracks let water seep in, which erodes the base and causes more movement.
- Trip hazards – Surface cracks become uneven, creating liability risks.
- Structural issues – Wall cracks or deep foundation cracks can weaken the integrity of your structure.
- Higher repair costs later – The longer you wait, the more damage you pay to fix.
Whether it’s concrete wall crack repair or patching a surface slab, early action is cheaper than a full replacement.
How to Prevent Concrete from Cracking (Step-by-Step)
1. Use the Right Mix
Work with a professional who knows how to balance cement, water, and aggregates for your climate and use.
2. Add Control Joints
These planned weak spots guide where the concrete will crack on purpose. Without them, cracks form randomly.
3. Prepare the Subgrade Properly
We compact and level the ground beneath the slab to avoid uneven settling later on.
4. Don’t Overwater the Mix
Too much water weakens the concrete and leads to shrinkage cracks.
5. Use Reinforcement
Rebar or mesh reinforcement helps support heavier loads and reduce spreading cracks.
6. Cure the Concrete Correctly
Curing is not just letting it dry, it involves keeping it moist for days to slow the process and prevent cracking.
These strategies are built into every job we do for Concrete Services.
Concrete Crack Repair: When to Call a Professional
Not all cracks need professional repair but many do. Here’s when to pick up the phone:
- The crack is wider than 1/8 inch
- It runs across the entire slab
- It’s getting longer over time
- It’s part of a retaining wall or foundation
- You’ve already tried DIY repair, but it didn’t hold

If the crack is small and stable, you might try sealing it yourself. Home Depot has a solid guide here on how to fix cracks in concrete with store bought sealant.
But if you’re unsure or if your slab supports a structure, get professional help.
