Best For Fixing Sole Plate to Flagstone Foundation

[JKBDIY]

Hello,

What fixings are best for fixing new stud wall to stone foundation? I've used Tapcon for this in the past and think they're excellent but that was in the USA. Is there a UK equivalent or shall I just drill with masonary bit, plug, and screw? If so, what size for 4"x2" sole plate on DPC then flagstone?

Thanks,

JB

Had to look up Tapcon, think these are similar unless someone says otherwise.

Thunderbolts

it depends what the flagstones are made of -if its sandstone and not too hard they will work

if very hard material, then you might be best with expanding plugs

Nr 5 screws and brown plugs.

Concrete screws or thunderbolt type fixings don't expand when driven in. They may be more suitable on a slab, particularly near the edges.
