Keep Your Building Up to Standards with Concrete Crack Repair

Wednesday, July 05, 2017

Concrete is one of the preferred masonry materials in industrial and commercial settings. It is durable, affordable, and easy to maintain. It can be used for both the structure of a building as well as the flooring. However, concrete needs regular maintenance, and that includes patching cracks in concrete. Your local painting contractors at Lakeside can help you keep your building up to standards with concrete crack repair.

What We Do

Lakeside Painting’s floor team specializes in repairing vertical edge damage, joints, cracks, spalling, pop-outs, gouges, bolt holes, and more.

Our professional painters work with both semi-rigid and structural polyurea products. These two types of products offer maximum flexibility while remaining rigid enough to preserve the structural integrity of the concrete’s edges. Since the products we use are relatively fast-curing, we can apply them in areas that withstand heavy amounts of foot traffic as well as areas that absorb hard wheel carts and heavy load fork trucks.

Similarly, our products are environmentally safe and contain no VOCs (volatile organic compounds); they are 100% stable. Having no odor or toxic vapor, when we patch your concrete, your everyday business will not be interrupted.

Your Options

As mentioned before, we typically utilize two types of products when patching concrete cracks: epoxies and polyurethane foam. Generally speaking, if the crack needs structural repairs and the area needs to be as strong or stronger than the surrounding concrete, epoxies should be used. Polyurethane is the best choice if you’re just seeking to prevent water leakage or repair a crack that is actively leaking.


Epoxies are injected into cracks and are available in a wide range of thicknesses. The varying viscosities accommodate cracks of different widths – the larger the crack, the more viscous the injected material ought to be.

Epoxies are advantageous because they have incredible compressive strength, making them even stronger than concrete at 12,000 psi. This is why epoxies are best for structural cracks. However, they do cure very slowly, taking hours from their injection to harden. This is good because it allows the epoxy to flow into even the tiniest crevice of the crack. On the flip side, its slow cure time means that the epoxy could very well flow out of the opposite end of the crack before it has had a chance to harden.


Polyurethanes are the best option if you are concerned about leakage. Polyurethanes are elastomeric and fast-setting, making them ideal for waterproofing. Since they are flexible, polyurethanes can accommodate slight movements in the concrete while ensuring that the seal remains intact. They harden within minutes of injection, reducing the likelihood that the product will flow out of the injected crack. While urethanes are awesome for basic crack filling, they add no compressive strength.

Regardless of which type of crack you’re looking to fill, the professionals at Lakeside Painting can meet that need.
