Crack Injection and Repair

If there are cracks in concrete there is a reason for it, and it should be addressed. While many people don’t see an issue with mild cracks, once a crack appears it will only grow. This is particularly important for large structures. It’s a prime opportunity for an epoxy crack injection solution.

At R + R, we provide epoxy crack repairs – a cost-effective solution used to strengthen structures that are weakened due to cracks. In addition to structural concrete cracks, there are other signs to look out for. For example, if water is appearing on you slabs or pooling where it didn’t previously, this could signify a concrete structural issue. Additionally, check windows. If you have trouble opening or closing a window or there are cracks in the drywall around the window, this is also a sign you have bigger issues.

What You Need To Know

Crack repairs are a simple, cost-effective solution to address potential structural issues before they have a chance to spiral out of control. The right solution to repair cracks will depend on the types of cracks present.

There are various injection products, including concrete crack injection epoxy, repair mortar, polyurethane crack injection, fast-setting semi-rigid polyurea joint repair, ardex injection t-port, and low viscosity structural crack injection repair. The right solution will depend on the injection range, whether you are dealing with major cracks or hairline cracks, and if there are other underlying issues.

What Does Crack Injection Do?

Whatever concrete crack repairs solution you choose, the purpose is concrete repairs. Epoxy injection is fast setting and will fill the crack to provide additional support. Repaired concrete is a necessary step to maintain structural integrity.

If you notice cracks in your home’s foundation, do not attempt a DIY solution. It’s important to have a trained professional assess the issue to recommend the appropriate solution.

Why Do You Need Crack Injection?

It’s common for civil infrastructure, such as buildings and bridges, to crack due to vibration, structural movement, and overloading. For example, when heavy vehicles repeatedly travel over a bridge, it will eventually result in concrete cracks. An epoxy crack injection is an ideal solution to provide these bridges and buildings with an effective epoxy repair solution that will strengthen the durability and stability of the structure.

If you have a rising damp issue, then damp-proof work is necessary to address it and prevent it from spreading. Whether it’s due to structural cracks or otherwise, the affected area is removed, and an injection system is used before the area is repaired. If you have had a damp issue in your home, opting for paint-containing protective coatings is your best bet moving forward.

The waterproofing membrane is part of the remedial waterproofing process in wet areas. In the event of water leaks, the area is protected. It is also a common step for balcony waterproofing. However, waterproofing solutions should be considered wherever water ingress is possible. These can be completed after the fact as one of your repair products. Sheet membranes can be installed after the crack injection is completed. Cracks can result from many issues, including structural changes due to the removal of water tanks or leaking cracks.

Leaking can undermine underground infrastructure, whether it’s a residential basement, a tunnel or a rail station. A crack injection system is a way to seal and waterproof unground leaks effectively. It is common for these types of structures to crack due to the liquids that pass through at volume over some time. While multipurpose epoxy repair adhesive is valuable, pressure injection techniques make the area watertight, provide a flexible bridge, and stave off future cracks.

Travel routes are also prone to cracking because they carry much weight. The correct crack injection will restore the travel route’s integrity, increase safe function, and protect against further cracks. Concrete slabs crack for various reasons, but they can be quickly restored.
