Not sure if I’ve missed something? Why do you need resin for concrete instead of standard security anchor bolts with ball bearings?
There are a few advantages to resin in use though only 1 is likely to apply here.
The main advantages of mechanical anchors are speed and lack of sensitivity to dust and contamination and lower cost.
The main advantages of resin are its suitable for use in broken/cracked/mixed materials. It’s suitable for use much closer to the edges of those materials. It tends to produce a better bond (with proper anchors). Suitable for use in weaker materials which would split when mechanicals are used eg soft brick, breeze block, aerated concrete blocks.
The only real advantage of resin over mechanical in this sort of application is down to material (you don’t want to fix 20mm from the edge of your slab). If it’s a solid pour concrete like in the video it’s an expensive faffy solution to a problem that doesn’t exist. If it’s cracked, damp, block work etc resin is the right answer.
