Best Crack Repair Methods

Best Crack Repair Methods

There are multiple methods of concrete crack repairs. However, the most famous are epoxy injection, grouting stitching, drilling, routing, sealing, etc. You might be wondering what method is most suitable. Before we look into that, we have to evaluate each type based on the evidence; only then the suitable method can be selected.

Methods of crack repair

Epoxy injection

This is the most commonly used method to fix the narrow cracks of not more than 0.002 inches. The process is closely associated with injecting the epoxy by pressure.

This method is widely used to fix the cracks in roads, dams, builds and other concrete structures. However, these cracks can reoccur if the root cause is not identified. If you cannot identify the root cause of the crack, you can go for other options that are ‘route and seal the crack,’ and the other one is a ‘joint’ method.’ In that method, repairers establish a joint between the crack to allow movement.


The process of epoxy injection is not as critical as it seems to be. All you have to do is first clean the crack as contaminants such as dirt, oil, etc., reduce the effectiveness. Then the surface is sealed with the appropriate material.

Routing and Sealing of cracks

This method is performed when there is no such need for repair. This method involves enlarging the crack and then further making it right with a suitable sealant joint. This method is comparatively simple and does not require a lot of training, unlike the epoxy injection. Moreover, this method is usually applied on flat surfaces such as concrete pavements and floors.

This method is used to treat the fine pattern cracks and comparatively larger cracks compared to epoxy injection. Commonly routing and sealing are used for the surface where the water stands and the cracks are established. Hydrostatic pressure is exerted on cracks to fix them. The sealants are of different materials such as epoxies, polysulfides, silicones, etc. However, the joint is handled with special attention so that it can be a permanent fix.


Stitching includes boring openings on the two sides of the break and grouting in U-moulded metal units with short legs (staples or stitching canines) that range the break, as demonstrated in Fig.3. Stitching might be utilized when elasticity should be restored across significant breaks.

The stitching methodology comprises penetrating openings on the two sides of the break, cleaning the openings, and mooring the staples’ legs in the openings, with either a non-psychologist group or an epoxy pitch-based holding framework.

In the majority of crack cases, stitching is the most optimum solution. It offers an ideal solution to most of the crack problems in walls. Stitching the crack also assists in preventing walls from getting moisture. In this way, stitching is the most reliable and effective way for crack repairing. It can be used easily without worrying about how to install stitching bars.

Drilling and plugging

If you have to repair a crack that runs in straight lines, drilling and plugging is the best suitable method to repair such cracks. Drilling and plugging are some of the most cost-effective methods to repair a vertical crack. All you have to do is to drill a hole in the position of the crack. It is then filled with grout and the tubes inserted in the hole that resists any leakage.

This crack repairing method does not require additional tools that you have to insert in the crack. It just requires drilling vertically and plug-in tubes. This makes it duly cost practical, comfortable, and time-saving to repair vertical cracks.


It is another method for crack repairing that includes filling the crack with flowable plastic material. It is usually used for filling damaged concrete structures. Grouting is not limited to a common material for repairing all kinds of cracks. It has different types.

Some of the grouting materials are:

  1. Fiber-reinforced grouting
  2. Cement sand grouting
  3. Gas forming grouting
  4. Sulfo-aluminate grouting
  5. Polymer injection grouting

All of these types are used to treat different types of cracks. It depends upon the intensity of the crack and the type of material that has to be repaired, and according to your need, you can select the optimum grouting material.
