Hiya. I'm new to these boards, so forgive me if I do anything wrong.
I need to build a low retaining wall for the garden (since I had some building work done.) I plan to use railway sleepers (new ones, not reclaimed.) The dimentions of the sleepers are 24cm x 12cm x 2.4m. Total height needed above ground level is about 30cm.
As you can see from the photo, I plan on putting them in 2 high, using the height rather than the width. The bottom sleeper will be well over half underground (as per piccie). I plan to link the sleepers together with Timberlok fasteners
My questions are ....
Do I need footings for this - concrete etc or am I OK just tampening the ground ? If I need concrete, what depth would you use?
Do I need vertical posts to secure the sleepers with - or should I be OK without (I thought I would be OK without because it isn't very high).
Any advice would be most welcome. Please bear in mind I'm far from experienced though.[/img]
