Ledger board for decking

[Ptdmitchell]

Hi all,

I've decided to build a deck at the rear of my propert but need some advice on the best fixings to attach the 6x2" ledger board to the wall. I've used 6x130 screws with 3x3mm M8 square plate washers behind each screw to leave a 9mm gap for drainage. The screws I've used have pulled in tight, but not as tight as I'd like, and are pulling into the wood. Should I use something like coach bolts instead to get a real firm fixing? Any advice would be welcome

Many thanks

Coach screws into decent plugs such as duopower should hold well, along with washers

If the masonry is friable, resin bond threaded rod into the wall using nuts and washes to create a gap, they will not pull out like plugs sometimes do. If the masonry is sound use masonry bolts that screw straight into drilled holes.
