Hi, I’m building a small platform which partially sits on the ground and partially sticks out from the slope. I’ll use H4 timber sleepers for the frame given the ground contact and have a footing in place to support the bit that sticks out. What’s the best/strongest way to join the sleepers to form the frame?
Also one end butts up against some reconstituted limestone. I’d like to join the sleeper to the limestone for added support. What’s the best way to do this?
Welcome to the Bunnings Workshop community @mjwillis. It's fantastic to have you join us, and many thanks for your question about joining sleepers.
It would be really helpful for our members when offering useful advice if you could provide a sketch of what you are hoping to achieve. That way, they'd be much better placed to provide suitable options. Let me know if you need a hand uploading an image.
Typically you'd join sleepers with landscape screws. You might like to employ the use of brackets to reinforce the internal corners for a stronger connection. Also, these brackets can be used to attach the sleepers to your limestone wall. I'd suggest using Ankascrews to attach the bracket to the wall.
