    I'm about to replace my old 5 bar gate with a pair of aluminium gates.

    The posts need to be bolted down.

    As the current surface is soil I need to lay a slab either side for the posts to go on.

    Any ideas how big the slab should be? or how to go about sizing them?


    The gates are about 2m tall prob about 30-40kg per leaf.

    Thanks in advance

    That seems an unusual way of fixing gates, most gates have a post that is sunk in the ground and concreted in.

    Indeed, I think it’s because they’re aluminium and it doesn’t react well with concrete.

    The posts have a base plate with pre-drilled holes already welded in place ready for mounting.

    if you run a ground beam between the two post bases, linking them together and pouring in one (preferably with some reinforcement) it will combat the tendency of the two gates to lean together, caused by the leverage of the weight on the posts.
