The Most Common Concreting Problems and Their Solutions

A number of problems can arise when concrete is not properly mixed and worked. Some of these include discolorations, cracking, and scaling. In addition to shrinkage, these problems can also be caused by improperly working the concrete. While concrete is relatively easy to work, if it is not mixed properly or worked improperly, it can have a number of problems. Discoloration is caused by a variety of issues, including poor workmanship, adding too much water at the job site, or adding too much calcium chloride to the mix.


Bleeding in concrete is the development of a layer of water on freshly placed concrete due to the upward migration of water and the settlement of solid particles. While some bleeding is normal, excessive bleeding can degrade the quality of concrete by increasing the water-to-cement ratio of the upper layer of concrete. Excessive bleeding in concrete also affects its durability properties. It is recommended to avoid any finishing operations while bleed water remains, visit concreting contractor rockhampton.

Despite its negative effects, bleeding in concrete can be controlled by controlling the water content, adding air entraining admixtures, or simply compaction. In some cases, the bleeding can be completely eliminated through a controlled re-vibration process. Bleeding in concrete can be avoided by following the proper proportions for the components of concrete. As long as bleeding is a very minor issue, it should not affect your project.


Crazing is one of the most common concrete problems. This type of crack is caused by an uneven amount of cement paste that rises to the surface during the process of concrete installation. Although it has no effect on the structural stability of concrete, crazing can have an aesthetic impact. In order to prevent crazing, it is essential to control moisture and properly cure concrete. If you notice any signs of crazing on your concrete floor, you should contact a concrete contractor.

Blisters are a common concrete problem, and can be easily repaired by modifying the concrete mix. Crazing cracks are also caused by a foundation that is shifting, and may require foundation repair. Depending on the type of concrete, you can also have your slab checked by a foundation contractor to ensure that it is stable. Likewise, if you notice any cracks in the concrete, you should contact a concrete company right away.


While concrete is a relatively easy material to work, it is susceptible to several problems, including discoloration, crazing, and shrinkage. Luckily, these issues are typically preventable, and can be prevented by using proper mixing procedures and avoiding common mistakes in concrete placement. The following list highlights some common concrete problems and their solutions. Read on to learn how to prevent and fix these common concrete problems! This list will help you avoid costly repairs and replacements.

The most common concrete problems and their solutions may vary. Some of these issues are cosmetic in nature, while others are more structural. Regardless of the cause, a concrete problem can affect the structure of a building and the final appearance. In general, concrete problems are preventable and easy to fix, but the solution to each problem varies. Once you’ve identified a problem, a solution will be available as soon as possible.


Although cracking in concrete usually does not extend beyond the edges of the slab, it can still be an issue. Cracks in concrete can be the result of a variety of causes, including settlement around steel reinforcement, shifting formwork, and large changes in temperature. As a result, these cracks can eventually lead to greater weakness and leakage, and may even cause rusting of reinforcement steel. In extreme cases, cracks may even lead to spalling.

Drying shrinkage cracks are the most common and misunderstood types of cracks in residential concrete. The concrete has the highest volume when it is poured, but as it hardens, water comes out of the concrete. This water is called bleed water, and its loss reduces the volume of the concrete. The concrete begins to shrink when it loses its bleed water, and this is what causes the largest cracks.


Efflorescence is a result of water infiltration into the concrete. It can occur in any area where there is high moisture or when salts are present in building materials. The resulting capillary action from water in the concrete can develop 300 to 500 pounds of pressure. This water pressure can cause the concrete to crack and spall. There are several common solutions to this problem. Listed below are some of the most common.

Efflorescence can be minimized by site surface drainage. Use of a well-graded concrete mix can minimize the paste. Make sure the concrete is not more than 4″ slump and is consolidated properly. In addition, concrete should be cured in some manner after being placed on a surface. These factors will reduce the presence of bleed water and create a lower capillary network.
