Top 7 Signs You Need A Professional For Concrete Repair

Concrete finds its use in most of the important areas of commercial buildings and homes. From the structure itself to driveway, sidewalks, garage, porch steps or patio, the material, due to its durability and strength, is builder’s favourite. But with time, even a lasting material like concrete can wear down. Constantly exposed to elements including external concrete, deteriorated concrete not just affects the visual appeal but also pose a serious threat to structure’s safety, which can further impact the property’s value. If you observe any of the following signs in your concrete, contact a concrete repair contractor to conduct a thorough site assessment and recommend the right repair solution.

Development Of Cracks

Rain and heat cause concrete to expand and contract which results in the development of cracks. Excess water in concrete during installation also impacts the strength of the material which can lead to shrinkage. The more the water is present in the concrete, the greater the shrinkage will be. Depending on the cause behind the preliminary damage, concrete cracks can be hairline cracks, shrinkage cracks, settlement cracks or structural cracks. Irrespective of the type, cracks can impact both the foundation of the structure as well as the areas supported by concrete. They also provide an entry point for water, air, moisture, and debris to get inside the surface which can cause further damage and safety hazards.

Uneven Concrete Surface

When the area beneath the concrete is unstable, it makes the surface uneven, a perfect recipe for tripping hazard and this instability can result from a variety of factors. When the ground is not properly graded and prepared before pouring concrete, it can cause weakening of the material and shifting and settling of cement. Or if a contractor hasn’t compacted the soil well before pouring, debris can enter holes which can lead to sinking. Climatic conditions and the ratio between water and cement mix also play a huge role in defining the strength of concrete. Tree roots are yet another reason that can lead to uneven concrete surfaces; if left unattended, they can cause sidewalks to lift and heave.

Accumulation Of Water

Water has the potential to make or break concrete. During heavy rains, water softens soil and during winters it breaks it down, impacting concrete’s strength. As accumulation of water raises the water-to-cement ratio, continually flowing water above and beneath the surface can also lead to sinking. Combine it with stress due to heavy movement, water can lead to concrete fractures with cracked pieces emerging from the surface. During construction too, if the concrete dries earlier than expected due to rapid evaporation, water and air can get trapped below the surface, weaking concrete further. Water should drain off concrete and any sign of pooling must not be ignored.


If you see pests or animals burrowing under your concrete, you will soon need a concrete repair specialist. Pests or animals can create void and perforation of soil beneath the surface, causing slabs to sink and with the running water flowing both above and beneath concrete, the material is bound to lose its strength which will eventually lead to shortening of its shelf life.


Concrete is affected by the elements it is exposed to and changing weather conditions can clear out the protective coating from the surface, leading to darkening, rust streaks and discolouration. When you start seeing a change in the colour of your concrete, contact a concrete repair company to have a look.


If you notice concrete in your patio or driveway chipping or falling off, it might be due to spalling. Spalling results from adding excess water to concrete mix during construction or from improper curing. The reason why one must always avail services from a credible and certified service provider. To fix spalling, resurfacing with concrete overlay is required which can be done easily with the help of a professional.


If your concrete has aged and worn off, it’s always a recommended practice to get it assessed by a professional and see if any further repair is required. Ageing can result from one or the combination of all the factors highlighted above and there is always a possibility of finding underlying issues that may not have been addressed and might impact the structure in the long run.

Concrete Cancer

This is not an apparent sign and might be identified only during inspection. Concrete cancer occurs when cracks in concrete expose steel to the surrounding elements. Interaction of steel with air and water leads to formation of carbonic acid which is responsible for corrosion. Concrete cancer can lead to crumbing or collapsing which is not only harmful to the structure but also to the inhabitants as it might result in life-threatening accidents.
