Post by: casper on April 27, 2019, 07:55
Hi, A local hardware supplier selling pressure treated decking boards and treated railway sleepers, sleepers 18 each, decking planks are thick 4 each, I would like to make raised beds, due to owning several dogs, which material do you recommend, and do u have a base or not, I want them to last too,pictures of your raised beds would be great too, thanks in advance

No base, you want worms to get in and water and roots to get out.  Factor in the cost of lining the sides of the beds,  wet soil will rot even thick treated timber.  Any plastic sheet with some uv resistance will do.

Any "new" treated timber will be treated with tanolith E which is perfectly safe if they're reclaimed they could be treated with coal oil creosote which I personally wouldn't use. As mentioned before whatevever you use line with DPC, it's available in widths from 4 inch to around 18 inch so you don't get much waste, as for which timber to use for me depends on budget, what tools are availeable and how strong you are. An 8 foot sleeper is heavy, expensive and hard to cut up and join back together without the right gear but lasts a long time and for me looks better. Decking is cheaper, easier to work with but will last a fraction of the time. I've used both on my plot and both do a good job.
