Guide to Concrete Repair and Protection

Concrete is a common aspect of construction projects worldwide. The reason is that concrete is strong, affordable and gives long-lasting results. However, despite being so tough even concrete suffers damage from wear-and-tear, water seepage, etc. Over time, a concrete surface can develop cracks, fractures and other structural damage. This can affect freshly laid concrete or old concrete structures.

Fortunately, there are solutions available that can easily remedy these structural and strength problems. With the right knowledge and skills, you can easily perform concrete repair and protection on old and new concrete structures.

In this blog, we have outlined the complete guide to concrete repair and protection using the most trusted products from reliable manufacturers Sakshi Chem Sciences Pvt Ltd.

What is the need for concrete repair?

There are several reasons that make concrete repairs necessary. For instance, time and weathering are the most common reasons of damage to concrete surfaces, as the surface is constantly exposed to harsh weather and climate. This usually results in developing cracks, flaking, peeling, and other types of damage.

Besides this, constant foot or vehicular traffic also tends to take a toll on concrete surfaces, resulting in wear-and-tear over time. Cracks, that are caused by ground movement or settling of the structure also raise the need for repairs.

No matter what the reasons, it is crucial to repair damaged concrete as soon as possible. If neglected, damage to concrete can get worse over time and potentially affect the basic integrity of the concrete structure. This can increase the cost, time and effort required to repair damaged concrete. According to studies, it costs several crore rupees to repair concrete damage in a year, in India.

What are the types of concrete repair?

Concrete can be repaired using one or more methods, with each having its own benefits and limitations. Th cause of damage and its extent usually determine the type of concrete repair needed for any concrete surface or structure –

Surface Repair

Surface repairs are usually meant to cover minor damage, such as surface wear, flaking, peeling, or cracking. This type of concrete repair requires filling the damaged part with a patching material to bring the surface to its original condition.

Surface repairs may need to be performed frequently, as the patching material can get worn away with time.

Structural Repair

Structural repairs are normally meant to fix significant damage, such as deep cracks or fractures that affect the structural integrity of the structure. This form of concrete repair requires reinforcing the damaged portion with steel bars or other similar materials to provide additional strength.

Decorative Repair

Often, damage to concrete surfaces can also affect the appearance of the structure. Decorative repairs remedy both aesthetic and structural problems. These are solved by using special patching materials that create a smooth and seamless appearance to match the surrounding original structure.

Why are concrete repair techniques important?

It is vital to use the right concrete repairing technique when trying to fix concrete damage. Inappropriate repairs can result in the problem recurring and creative safety hazards for those living in the building.

For instance, you cannot use surface repair techniques to fix structural damage as this will only temporarily hide the damage, and not improve its ability to bear heavy weights. In contrast, using structural repair methods to amend minor cracks or peeling often results in unnecessary damage and costs more to repair.

Besides this, selecting the correct concrete repair and protection technique is as important as using high-quality concrete repair products and following the proper application instructions. These points will ensure the repair is effective and long-lasting too.

How to choose the right concrete repairing material?

Using the right concrete repairing material is essential to ensure successful restoration of concrete structures.

Here are some factors to keep in mind when selecting a concrete repair product –

  • Type of damage

We have already explained how different types of damage require different types of repairs. You should ensure that the concrete repairing product you choose is designed for the specific type of repair required.

  • Product performance

Choose products that are tested and proven to provide durable repairing solutions. This will help save time and money in the future.

  • Eco-Friendly products

Choose concrete repair products that are environmentally friendly and safer for the workers performing the repairs. Besides this, the repair material should not have any negative or harmful effects on the health and well-being of people who live in the building.

  • Ease of Use

There are types of concrete damage that may require specialized equipment and technical expertise to ensure effective and strong repairs. On the other hand, some concrete repairs are simple and can be done by anyone with the basic know-how to use concrete admixtures and use concrete. Make sure to consider the level of experience and the equipment you have before deciding to hire experts for concrete repairs.
