    Default Avoid treated pine sleepers bowing

    18 months ago I laid some (200x50) treated pine sleepers flat as a temporary mow strip edging until I got around to affording a proper paver edge. As it turned out, the sleepers actually looked ok against the planter boxes as you can see in my pic so I decided they might not to be replaced. They were simply laid onto some compacted soil/crushed rock with very little peparation

    The only downside is that some of them bowed as they dried. Some looked badly out of shape within days, others became slightly "off" after a few months.

    Because I have grown to like the look of them for their location, apart from the "bowing" I would like to use more of these sleepers in another area as a mow strip.

    I'm looking for suggestions to avoid the bowing of treated pine sleepers. Selecting the best ones that are flat, usually means they are still in a pallet and still damp but eventually warp as they dry out.

    Will allowing them to dry out with some strategically placed weight for a while help them stay flat?

    In reality, that's about as good as it gets. Chasing nirvana in treated pine behaviour and stability will only lead to pain

    I found it best to buy them wet and install while still wet, as long as they are securely fixed in place. I also select ones I think look stable.

    True that. I really like the look of treated pine edging but the warping does my head in. My solution for a recent fence build was to use secondhand composite decking boards (not common to find) on the ground (plinth) that way pine sleepers didn't go banana and do my head in. But for the money new composite stuff is not budget friendly. But on the bright side if its just edging, it would go a long way and the contrast you can achieve with the timber has a nice aesthetic.

    You can actually get composite sleepers now.
