One of the things we often come across when doing an estimate for settled concrete is cracks, sometimes a lot of cracks. People ask “is there anything that you can do with these cracks”

The simple answer is “yes, but” the “but” being what is your end goal? If the goal is to make the crack invisible there’s nothing that can be done short of a complete overlay of the slab to fix the crack and even then slight cracks will often remain. Decorative overlays cost in the neighborhood of $4 to $12 or more a square foot. On the high-end $12 you can generally get brand-new concrete poured of course it won’t have that fantastic decorative look of an overlay.

The fix that we most often recommend is simply caulking the joint or crack with a material that closely matches the concrete or that will be sanded or textured too closely match the concrete. This works best with joints due to the fact that they are nice and straight and not jagged and of various wits and depths like cracks are.

Here at Slabjack Geotechnical we primarily use a custom formulated silicone caulk for concrete however if we are removing previously installed polyurethane we generally will use polyurethane again since it sticks to itself so well.

Take a look at our websites before and after pictures. We try to update it every few months with new projects and this winter we will be adding a lot more content relating to caulking since so much of our work revolves around it now.
