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.
We use the Pagani DPM 30. It is a wonderful machine if you are using it regularly. If you are only doing a few per year it is better to hire someone who already has one.
That is a great question. This job was great because the demolition work was already done. Typically, we just need the flooring taken up prior to lifting. In some cases, the customer may just have us drill through the flooring, with the understanding they will have to repair it in the future.
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.
Wow i find it shocking that people are so fast at showing their stupidity and make fraudulent videos on how to do something then they screw that up even like this idiot started with a crack but then is improperly filling an expansion joint and no crack filled at all but if you want to fill an expansion joint you use 2 inch tape on each side then fill the joint and smooth with a 2 inch wide puddy knife and done
@williamcoble the last thing I wanted to do is offend you good sir! I am posting some photos of crack repair on our IG @truliftconcrete right now just for you!
For every inch we grind we slope it back a foot. Then we take a hand grinder to smooth it out a bit more. Grinding is our last resort when lifting and replacement are not an option for the customer.
We use a high active solid penetrating siloxane sealer. It does not form a film on the top, but penetrates and fills the pores of the concrete. This does not change look or slip resistance of the slab. Only con is that the product is about 4x the cost of cheaper sealants.
