Gravel Boards

What ho one and all,

I am getting organised to replace number of wooden fence panels that have been there for around 20 years a well past their sell-by date.

I have the panels which I will be giving a coat of Ducks Back before installing.

Having cleared away most of the earth / leaves / moss / twigs / ivy from the bottom of the fence, the current rubbish timber is of course, well rotted. So I am thinking of installing some gavel boards but con't plan to spend a great deal of money.

Gravel boards come as pressure treated. However, I have a number of usable joists (50 x 150 x 4m) from the build that have been under cover for the last ten years. I don't know if they were pressure treated but if they get a coat of wood preservative, is there any reason that I should not use them?

Basically, I'm wondering if joists (with wood treatment applied) is likely to be better or worse than gravel boards, which are already poor quality wood?

Thanks and toodle pip

    If they can be cut to fit then I don't see why not.  Wood preservatives (including pressure treated) don't help much with preserving wood which is in contact with soil, so they'll still start rotting at the bottom, but the extra thickness compared to standard gravel boards (usually 19mm) will mean they should last much longer, and may even outlast the panels.
    A trowel in the hand is worth a thousand lost under a bush.

    That tends to be my thoughts; thanks for your response.

    My experience is that all the outdoor wood, pressure treated or not, is of such low quality because it is fast growing, that it does not really last.

    Per a post the other day, there are alternatives at British Recycled Plastics for this sort of thing.  Possibly dearer but much more durable?

    Agreed that more durable would be best, but the current bit of rubbish has been there for 20 years (I asked the neighbour who has lived there since 2000) so if anything I do to replace, lasts another twenty, I will either be old enough not to care or more likely, way past caring.  SEP  (Someone Else's Problem!)
