3 Ways to Repair Concrete Flooring

Problems with concrete are amongst the most common flooring challenges, since it appears that, at some point, most floors will gain spalls, holes or cracks. And a lot of these issues can be caused by the passage of time and dampness, as well as maintenance staff or contractors. Given that concrete is a familiar substance, it might seem like fixing it is no big deal, but the fact is not everyone can do it properly.

There are several things to take into consideration while fixing a damaged concrete floor:

Clean it First

Pouring wet concrete into the damaged area in your flooring won’t do in the long term. The edges of the problem need to be prepared correctly and with the right supplies. Deeper holes need a concrete mix with a stone aggregate, since that works well with the existing concrete, and a shallower crack or hole just requires a sand mix.

But before applying those materials into the damaged area, you need to clean it by sweeping, scrubbing any oil patches or stains, and use a pressure washer to make sure all the debris is taken out. If you have a sealant on your flooring, it’ll have to be removed before applying the mixtures.

 

Epoxy

If the concrete cracks and that crack moves due to temperature changes, merely filling the crack can result in another one forming nearby. If they’re likely to continue moving, then they should be treated as floor joints. And to fix a floor joint it’s necessary to re-cut, clean out and seal it with a floor joint sealant.

If the crack is stationary, it can be repaired and sealed before the application of the new resin. The best procedure and materials for this depends on the width, depth and length of the crack, and it’s likely that a part of the floor will need to be cut out to remove any loose substances, before being sealed with epoxy mortar.

Screeding

Sometimes the concrete will sink, making it difficult to work in a warehouse of factory, especially if heavy machinery is moving around frequently. This could be due to poor compaction of the materials beneath the concrete which, by shifting over time, will cause the concrete surface to sink and crack. To fix a floor that has subsided, if the issue is not too extreme (or easily fixed by polishing the floor), laying a self-levelling screed over the surface should do the trick.
