stone wall fixings?

[rmt]

Hi
I intend to fit an extending canopy to an outside wall of my house but it is a very old wall of uneven stone and I assume lime render, it is almost imposable to drill & plug a secure fixing, is there a type of filler which can be used and if so what is the procedure?
thanks

Drill into the stone and use a resin fixing agent to anchor the bolts

Tricky one, how thick is the wall? You'll probably have more luck drilling right through and bolting to the inside.

the wall is approx 2 feet thick, large ish stone either side rendered with smaller coble infill
