Maintenance & Repair
Cracks, sealing, cleaning, resurfacing, and the honest repair-versus-replace decision.
Most concrete doesn't fail. It gets neglected in small, cheap-to-prevent ways for fifteen years and then fails all at once. Sealing on a schedule, keeping joints clear, and moving water away from the slab edge account for the overwhelming majority of the difference between a slab that lasts and one that doesn't.
The other half of this category is diagnosis. Not every crack is a problem, and the ones that are look different from the ones that aren't. These guides give you the same tests we use on a site visit so you can tell which situation you're in before anyone quotes you.
If a contractor has told you a slab needs replacing, read the repair-versus-replacement guide first.
