Why Crack Size & Depth Matter

Crack size and depth determine the type of repair needed and the long-term durability of the fix. Small, hairline cracks may seem minor, but they can allow moisture and contaminants to seep in, leading to expansion and further deterioration. Shallow cracks in low-traffic areas might only require a surface sealer, while deeper cracks, especially those that reach the structural layers of concrete, need stronger solutions like epoxy injections or polyurethane fillers to restore strength and prevent further damage. Choosing the wrong repair method can result in temporary fixes that fail under stress, leading to more extensive and costly repairs down the line. By identifying the right crack size and depth, you ensure that the repair method is suited to the concrete’s needs, extending its lifespan and maintaining its integrity.

What Happens If Cracks Are Ignored?

Leaving concrete cracks untreated can turn a minor issue into a costly problem. Small cracks can widen over time due to temperature changes, water infiltration, and regular wear. When moisture seeps in and freezes, it expands, causing the cracks to grow and weaken the concrete structure. In high-traffic areas, ignored cracks can lead to surface crumbling, creating safety hazards and increasing the need for resurfacing. Structural cracks in driveways, garages, or industrial floors can result in uneven surfaces, making them more prone to heavy impact damage. For polished or decorative concrete, even small cracks can ruin the appearance and require refinishing. Addressing cracks early with the correct repair method prevents further damage, protects the floor’s strength, and saves money by avoiding complete replacements or extensive patching.
