I've bought a canopy for my side passage. It came with very substantial fixings that would have been great if my brickwork suited them. The problem is that my exterior bricks are very hard indeed for c.25mm in, then there's a void until the drill hits the other side. The supplied fixings were suited to solid bricks and are designed to expand where my bricks have the void, so are of no use.
The question is what fastening combination is suited to such brickwork? The canopy supports are plastic, although chunky, and the 'glasswork' is transparent, corrugated plastic sheeting. The total weight of the structure is not great, of course, but the load from winds whipping down the side passage will put much more strain on the fixings.
Any recommendations/guidance much appreciated.
