10 drill holes (8mm diameter, 50 mm length) in a concrete ceiling were filled using a high strength concrete repair product and a bonding agent. It's been curing for a whole year. What are the chances of drilling in the repaired area is secure to han a curtain pole? Since the surface is painted is not possible to determine where the old holes were

If It crumbles just use epoxy resin to secure the bolts/fixings. Start with a small drill bit and work up.
Thanks!
