How to fix fence post to concrete patio slab


Recommended Posts

Slatted screen to be erected around patio. 44mm slats with 16mm gaps to form privacy screen. Surface of patio is concrete patio slabs.

Thinking of 4x4 fence posts but need to fix them to the patio. Slatted panels will be 2 x 1800mm (3.6m in one direction) then at right angles 2 x 1800mm. (3.6m at right angles to first).

Main challenge is withstanding the occasioinal storm. What would work?

It really depends how the patio slabs are fixed down and on what sub base, I would worry about wind,s pulling the fence/slab away from the ground (which is your question, I get that). The screen is slatted so not a complete sail but still will catch some “air”. If you believe the slabs are fixed well enough then metal post feet bolted to the slab will be sufficient.

I would be drilling 300 to 500mm odd deep to resist force, and resin fix threaded bar through the various foundation sub layers as best I could!
