Driveway cracks form when the surface shifts, settles, or wears down over time. The success of any concrete crack repair depends on proper preparation and the right materials. If the surface isn’t cleaned, treated, and conditioned correctly, the patch won’t bond, and the damage will return.

At Olson Foundation Repair, we focus on process, not shortcuts. Every repair begins with assessing the crack’s severity, preparing the surface, and controlling moisture to ensure a strong, lasting seal.

Preparation and Treatment Process

Repairing cracks in concrete starts with assessing their severity, prepping the surface, and choosing the correct filler or sealer. Skipping these steps usually leads to short-lived results.

Step 1: Chip Out and Clean the Crack

Depending on how large or deep the crack is, you may need to chip out the ledge so the surface becomes flush. This ensures that when you apply new material, it bonds evenly without leaving raised edges. After that, blow the area out with a blower to remove any dirt or dust before moving forward.

Step 2: Wet the Surface Before Applying Material

When performing any concrete crack repair, the surface must be damp. Concrete should never be applied over dry concrete; it will not adhere properly. Wetting the area helps the new material stick, leading to a smoother, stronger bond once the filler cures.

Pro Tip: Always wet the surface before applying a cement-based filler. The added moisture strengthens adhesion and prevents the repair from breaking loose.

Step 3: Choose the Right Filler or Sealer

Once the surface is prepped and damp, apply either a concrete filler sealer or a caulk-type filler, depending on the crack’s size and location.

• For general cracks: Apply a concrete filler or sealer after wetting the surface.
• For small cracks between porches, steps, or entryways: Brush the area clean and dry it completely before applying a silicone or gap-filling material.

Each method works best when the surface condition matches the product’s requirements: wet for concrete-based sealers, dry for silicone or caulk fillers.

Common Mistakes in DIY Crack Repair

Many homeowners attempt small concrete fixes themselves, but often make mistakes that affect the results. Our team sees the same issues repeatedly when evaluating failed DIY repairs.

Using the Wrong Material

People sometimes buy the wrong product for the job. The material must match the type of crack and surface being repaired. Choosing the wrong filler causes weak adhesion and a poor finish that doesn’t last long.

Skipping Surface Preparation

The most common problem is failing to clean or wet the area before applying new material. Without proper preparation, the product won’t bond and will end up peeling or cracking again soon after application.

Key Takeaway: Good prep and correct product choice are the foundation of successful repair. Skipping those steps always leads to poor results and wasted effort.

Maintenance and Long-Term Considerations

There isn’t much maintenance involved once a driveway crack is properly sealed. Driveways, patios, and sidewalks rest on natural ground that moves with moisture changes. Our area’s expansive clay soil expands and contracts, which causes the concrete to move slightly over time.

Because of this, cracks may reappear eventually, even with professional repair. The soil “breathes,” reacting to the changing seasons, from freezing winters to hot summers. These shifts make the ground move and can cause minor cracking again later.

Pro Tip: Don’t overdo the repairs. Focus on proper prep, sealing, and ongoing observation. Small surface cracks will likely return, but well-done repairs extend your driveway’s life and reduce future damage.
