Concrete Post for fencing query

    Starting to plan this job. Will be using 1.8m panels and 300mm concrete gravel boards and 2.7m concrete posts. Garden has block walls on either side and I'm fencing in the back which is open.

    Question around where the fence meets a garden wall on either side. I've cleared out along where the gravel boards will be but where the first and last post would go there is a large concrete foundation for the wall (no surprise)

    Options are:

    1) dig out around foundation for a post (don't fancy that!)
    2) use a cut down concrete for 1st/last post, attached to side wall with fixings and use as normal
    3) use a wooden post instead of concrete for 1st/last post, attached to side wall with fixings and then use clips to attach gravel board/fence panel to the wooden post
    4) no wooden/concrete post, just attach clips for gravel board/panel directly to the wall.

    I'm thinking #3 (#2) for ease of cutting? same principle but wonder if means any extra load on side walls?

    What is typically done?

    I think I'd just use brackets on the wall to hold the timber (and gravel board) in place.

    If you dont like the look you can easily try another option and you haven't really wasted much time.

    I have done this several times but u need the right tools. Option 2, cut post to correct height. It will have metal running through it do wear goggles. Pre drill 2 holes, top n bottom,in the slot where timber slides down. Get post in position and through these holes mark on wall where u need to drill into. Move post and drill the holes .then use frame fixers or express nails to attach to wall job done. Hope all this makes sense.

    Drilling through those posts is painful as they are full of aggregate and you risk cracking the post itself (it wont fall apart due to the rebar)

    Cheers,

    I have an SDS drill so I'll go with that to drill it, just have to borrow/rent a consaw to cut the post to size, will need it anyway to sort the cut a gravel board anyway..

    All makes sense- just wanted to hear someone else's thoughts so I wasn't going ott.

    If all else fails then I get gravel brackets and panel brackets next time a hardware/Homebase etc.. opens!
