Thank you for the advice on retaining wall drainage!

Hi Hester,
Thanks for your questions
The timbers are old railway sleepers, no treatment , just aged.
Yes they are in Concrete.

Hi Linda

Thanks for your question.
The type of material used for retaining depends on a number of factors
- height and strength required
- aesthetic appeal
- durability requirement
The type of wood used in the photo was dense old hardwood recycled from railway sleepers. These were supported by upright sleepers slightly cantilevered and set in concrete to the same depth as the height of the wall from the ground.
This would have a life of about 15-20 yrs if it was drained from the rear using permeable medium such as gravel and agricultural drainage pipe.
I hope this helps you
