Attach something to Brick...How?

andrelaplume2June 1, 2011

I have a brick chimney. Alongside it is our old Giant Propane tank. I built a 3'W x 5'H picket fence section, stained it and used those heavy duty 7' long green fence posts (for chain link) to secure the section in the ground...there was not enough room to dig 4x4 posts least on the left side anyway.

The sucker is likely fine as is but in a HEAVY wind I could see it how it could sway forward / backward. The fence section sits at an angle to the chiminey. I'd like to add a bracket to the center 2 x 4 on the fence section connecting it to the chiminey. That would prevent any sway. How can I affix my bracket to the chiminey....screw into the block...the mortar etc...

You could attach a 1x4 wood strip to the chimney with cut masonry nails into the mortar joints, then screw the bracket into the wood, or you could use a hammer drill to make the holes necessary for some plastic anchors and attach the bracket directly. The masonry nails have no power to hold into the material, but they effectively pin it from side-to-side movement. You would have to determine if such a fixity suits your design. Anchors have side-to-side fixity and withdrawal resistance to boot.

Either is fine sine you do not require an actual rated joint.

Make sure you use the correct size drill bit for Tapcons, a drill at least 1/2 inch or so deeper than the screw will be inserted, and then blow the dust out of the hole.

Oversize holes really weaken tapcons withdrawal strength.
