In many ways, concrete is a tough substance. It is composed of a variety of ingredients that are hard by themselves and when combined together form a strong surface or known as the maturity of concrete which relate to concrete strength at a specific time. But there is one way in which concrete can be made vulnerable-cracks.

If you have a crack in your concrete, it's important to know how to fix it before it causes more damage. We will explore the benefits of concrete crack injections and what they entail!

In recent years, the popularity of using epoxy injection for repairing cracks has increased significantly because they provide long-lasting protection from water penetration as well as improving aesthetics. Epoxy injections are also very cost-effective since they use less material than other popular solutions such as pouring or spraying sealant on top of the crack.

What is Concrete Crack Injection, and what are the benefits of this service

Concrete crack injections, or concrete injection, is a technique that entails the injection of a watertight, durable epoxy to repair cracks in concrete. Different from other methods of repairing cracks in concrete such as pouring or spraying sealant over them, the advantage of using an injection is that it doesn't use a lot of material and can last up to five times longer.

How does it work?

When the injection is done, a urethane-based material is mixed and then injected into the cracks in the concrete. A nozzle that's typically part of the kit injects this solution into the cracks formed by concrete.

This mixture can also be applied with a pump, tube or gravity feeder. The mixture will harden over a period of time and push out any debris from the cracks, filling them up once it solidifies.

The Benefits:

The benefits of using this technique to fix your crack are numerous. Firstly, it works without gaps and has been proven to last for years on end with no maintenance required. In addition to that, the epoxy sealant is watertight which means that there is no worry about water seeping into the cracks and causing further damage to your concrete.

Lastly, the process is safe and cost-effective since there is no need for power tools or heavy machinery which work can be performed by one single person in any weather condition.

The process for getting a concrete crack injection

Getting a concrete crack injection requires you to first clean the cracks with a heavy-duty cleaner and air dry it after. Next, a colourfast coating is applied to make sure that it doesn't stain your outside surfaces. This can be done by a professional crack injection company that provides the service.

Next, you will need an epoxy sealant or adhesive. Apply this to fill in the gaps of the cracks. The final step is to cover up any trace of material on the surface by painting over it with exterior paint.

It is important to know if you have a crack in your concrete, it's also important to know how to fix it before it causes more damage. Crack injections are the perfect solution for this and come with multiple benefits such as being cost-effective and safe.
