On espeleo i aigua there is a short article about this new type of remoeable anchor by ClimbTech. It is load is rated 22 Kn, but unfortunately you have to drill at least 0,75 inch’ wide and 3 inch deep (approx 19mm wide and 75mm deep). You can see a fascinating video about testing the gear here and here. Does any one know a smaller version?
