Concrete Repair and Problems

Concrete is one of the strongest and most durable construction materials used by man. It is in everything from home interiors to large dams and bridges. However, there are a number of concrete problems that may occur and will need repair. To begin performing concrete repair, you must first identify the nature of the problem. Many problems are better prevented than they are later fixed but if you need to tackle a repair project yourself, there are many kits and tricks available that will help ensure that you successfully repair all of your concrete problems and restore your concrete's strength and durability.

One common problem that affects concrete is dusting. Dusting is when loose particles, or fine dust, begin to accumulate on the surface of the concrete structure. This often occurs due to inadequate ventilation or if the surface of the concrete has previously been subjected to freezing. It may also occur when the concrete has been trowelled with bleed water. The water blends with water in the concrete and as a result, the concrete is worn down ad becomes weakened. To repair dusting the repair must take place on the concrete's surface.

 

Another common concrete problem that will need repair is peeling or flaking. This is when the concrete surface has been exposed to freezing temperatures and subsequently thawed out. When this occurs, the top layer of the concrete will take on a dry and flaky appearance. To repair flaky or scaling concrete, you will need to peel off the top or surface layer of the scaling concrete. After you have removed all of the loose concrete, you will need to pressure wash the surface to ensure that any remaining loose particles are thoroughly removed. You will then patch the remaining areas until you have created a level surface. When you are finished repairing and patching the surface, you may want to overlay it so that it has a finished and uniform look.

 

Cracks are one of the most common problems that require concrete repair. There are several reasons why concrete cracks and they are the result of a variety of causes. First there is crazing. Crazing occurs when the surface of the concrete dried to quickly and did not have adequate time for proper curing. The result is a network or a web appearance of fine hairline cracks that spread throughout the surface of the concrete. This may also occur when bleed water is on the surface of the concrete and the concrete was finished, or if someone tried to dry up the water quickly by adding cement. It is best to let concrete cure slowly and wait until the process is finished to prevent cracks and crazing. Some other causes of cracking may be due to concrete being subjected to the pressure of freezing conditions and then thawing out, external pressure that causes the concrete to become stressed, and settlement. There are many compounds available that you can use to repair cracks in concrete. Choose the repair compound that best meets your project needs and apply. You will need to smooth away any loose debris from the crack before repairing and you should also be prepared to seal the crack after repair.
