If I do need to take 10mm out of the concrete, what is the best way?
Armeg scutch chisel and 3.2J SDS do not sound like they could handle
2x1m area?

Looks like I have a scale of removal...
- Marcrist BF750 diamond disc slot, try breakout with 5J SDS
- Marcrist CCU850X core stitch drill, try breakout with 5J SDS
- Apply 40J electric breaker
- Apply diesel, fertiliser, aluminium powder

Can not get there to do a test hole yet.
