Concrete Repair Methods: How to Repair Cracks in Concrete

Several concrete repair methods exist to treat small cracks in concrete. Concrete maintenance is essential because a small crack today becomes a big problem down the road. 

To remedy these issues, we utilize an array of techniques. Today, we want to cover a few common concrete repair methods typical to concrete paving contractors. 

Epoxy Injections

With an epoxy injection, we can correct a small crack in the concrete. Generally speaking, this is a fairly simple technique. Moreover, it helps to establish inlet and ventilation holes at intervals along the crack. 

From there, we seal the surface by applying the epoxy under pressure. While simple, using this injection requires a bit of know-how. At low temperatures, it hardens quickly. 

That means you need a bit of experience to get the job done right the first time. 


When we talk about “sewing,” we don’t mean fabric. Among concrete repair methods, sewing is a little more involved. It requires drilling holes on both sides of a crack. Then, we join the holes with U-shaped pieces of metal. 

For instance, we might use prestressed steel rods or reinforced girders. The “seam” in the process undergoes a good amount of stress as the construction passes through the cracked area. 

Routing, Patching, Sealing

Generally speaking, we employ routing and patching to repair flat surfaces. This is great for floors and sidewalks. However, some companies also apply it to vertical or curved surfaces. 

That includes some posts, piles, and pipes. Typically, this method requires us to make the crack larger at first. However, that merely allows our team to close it with a joint sealant. 

Drilling & Plugging

In this process, your concrete contractor enlarges the crack with a drill. Then, they seal it until it has the shape of a key. Generally, this technique only works when the crack is fairly straight. 

Moreover, it requires that one end is accessible. Typically, paving companies employ this method to repair vertical cracks in retaining walls. 

The “key” prevents the concrete sections adjacent to the crack from moving. Additionally, it helps to reduce leakage through the cracking and helps prevent soil loss. 

Concrete Repair Methods: Which One Is Right?

When we choose from our various concrete repair methods, we consider numerous factors. First, we determine how extensive the crack is. The further it develops, the more complex methods we have to consider. 

Additionally, it’s essential to determine the cause of the crack. For instance, shrinkage causes cracks in some concrete. In some cases, it stabilizes on its own. 

Alternatively, if the foundation never properly settles, you have to address that issue before you repair the concrete. Otherwise, the problem pops up again and again.
