DIY concrete repair

Cracks in concrete not only make your driveway, patio, or steps look undervalued, they can also lead to further problems as moisture seeps into the concrete. Prevention and maintenance is always your best protection against further costly and unnecessary problems. If you’re looking at fixing your damaged concrete yourself, using our DIY concrete repair will help you get the job done the easy way.

Whether you’re fixing a crack in your driveway, a concrete floor or a pothole, we can guide you in the right direction so you can fix it yourself with confidence.

The different causes of damaged concrete

Before you repair anything, it’s best to know what caused the problem in the first place so you not only have a better understanding but have a better chance of success with a DIY concrete repair that lasts longer.


Concrete corrosion is the chemical, colloidal deterioration or disintegration of solid concrete components and structures due to attack by reactive liquids and gases.

Corrosion is one of the biggest causes of concrete deterioration, so reinforced concrete must be installed and maintained correctly to minimize the risk of damage.

Temperature variations in concrete

Changes in the temperature of concrete can cause cracking. As the concrete gets hotter, it expands; as concrete gets cooler, it contracts. This is similar to many other materials you have probably learned about.

Plastic shrinkage

When the concrete is still in its plastic state before the hardening phase, it is full of water. This water takes up space and makes the slab a certain size. As the slab loses moisture while curing it gets a bit smaller.

Freeze-thaw cycle

If your concrete floor is located outdoors, it’s exposed to many elements. That means rain, wind, and the endless freeze-thaw cycle, to name just a few natural forces. Like corrosion, moisture is another primary culprit of concrete damage. When excess moisture in your concrete freezes, it expands, putting pressure on cavities within the material.

The concrete dries too quickly on application

If the concrete dries too quickly, it will lose moisture which can cause fine cracks throughout the concrete.

Improper installation

Improperly constructed joints, excessive moisture during curing or in the mix, and premature sealing are just a few potential examples of an installation gone wrong. Signs the job was rushed is finding crazing, spalling, and blisters.

How to tell your concrete needs repairing

Cracks appearing in the concrete

The most obvious sign that your concrete may need repair work is the appearance of cracks. Cracks in concrete can be caused by the soil underneath expanding and contracting due to weather conditions. If you have noticed cracks in your concrete, repair them promptly or seek professional advice.

Signs of concrete ageing

Like everything, expect concrete to age over time. A combination of cracks, pooling water, potholes, and unevenness are all signs of damage caused by ageing. The concrete will have noticeable signs of ageing and will look worn out. 

An uneven appearance

Another sign that concrete repair is necessary – if your concrete floors, external areas, or walls seem uneven. If you fail to take action when you notice your concrete areas are no longer even, you could end up with a serious issue. This includes crumbling and breaking, which causes instability and could also lead to injury. 


Like cracks, potholes are caused when the ground underneath it expands and contracts, as well as by the constant pressure from your vehicles. A pothole is more hazardous than a crack, as the hole can cause serious damage to not only cars but to people who use the driveway.
