hilti question

I have a friend who wants to attach a fence (corner) post to his house foundation. The foundation is block and I don't know if it is filled with concrete or not. Would the block hold up if we shot hilti pins into it? He originally used masonry screws to hold the post up but it wiggled free within a year.

no, shots is not the right answer. Must be block wall if anchors did not hold up. Use lead anchors with bolts and a lock washer. Try to drill into the mortar so as to not break the block cells.

I encountered a similar problem when I built and electrified parking fence for my parking lot. I anchored one end of the fence to a 2X4 that was fastened to the side of my brick veneer with Tapcon screws.

Within a year or two the Tapcon screws had effectively let go and the board that the cable to the parking plugs was fastened to was loose.

The reason why is that your fence will move up and down with the ground in winter due to frost heave, but your house's foundation is below the frost line, so the house won't move, or will move very little. As a result of the relative movement between the house and the fence, anchoring a fence to a house is just a bad idea.

What you should do is put in another fence post about a foot ie two from the house, have the fence itself coming to within an inch or so from the house, and if you need to run electric power along that fence, use a flexible cable housing to make the jump from the house to the fence. The flexible cable housing will allow for a bit of movement between the two.

Wahoo, I recently did a job a lot like the one you are talking about. I used a sleeve anchor. I bought them on LINK REMOVED I have used them in the past and I have never had a problem. The sleeve anchor is designed for block and brick.

drill sholes into the block, if filled with concrete. Match the poisition of the hole on the post, use Simpson SET-2 anchoring epoxy in the hole, insert the bolts thru the post into the drilled hole. You will need a tank to pull the bolt out after the epoxy sets. It's used for retro fitting foundation bolts.

thanks everybody,

We used the sleeve anchors and set the post to the foundation above ground. I feel pretty confident about it. Only time will tell.
