We love fixing cracks in concrete. We use a high quality silicone sealant designed specifically for concrete with vehicular traffic. Before we can seal cracks though, we have to grind them. This is where we get this question the most!

We use geotechnical polyurethane injection to lift concrete. Sometimes we do this in conjunction with our mechanical jack.

Should use a cartridge 3m type industrial mask and not the cheap type mask in the video because of the bad news/nasty dangerous silica in the dust when grinding or cutting concrete. People - Google dangers to lungs from silica (quartz?) In the dust from grinding or cutting concrete.

What's the difference between a poly sealant and a concrete specific epoxy fix ? Is the former better for expected frost-thaw cycles & seismic activity?

We don't recommend polyurethane sealant, and definitely don't recommend epoxy. Both of those tend to get very rigid over time, and are not UV stable. You will usually find polyurethane sealant in the big box stores because they are easy to install. If you want to do it properly we would recommend a concrete specific silicone that is DOT rated such as Dowsil 888, or Alchatek AP Slabseal 142.
