Question

Has anyone used gravel boards as a retaining wall? Can I see your pics please  

Answer 1

I would personally use sleepers as alot thicker and stronger

Answer 2

Depends on how many high you go and how you plan on fixing I'm just about to rip out that's two high and they've collapsed under the weight

Answer 3

You can but add extra support in the middle

Answer 4

Are you using the concrete posts that come with a fence with them?  

Comments

@nagel yes using 3 concrete posts, one either end and one in the middle

@inimical719 yea put them tight should be fine

@nagel thanks

Answer 5

They have a tendency to crack. Not designed to hold weight

Answer 6

The middle is retained by gravel Boards and concrete posts.  

Answer 7

Just to add, the area is 12ft wide x 5ft high and the garden goes back about 20ft on a slight incline so I was thinking 3 concrete posts and 10 gravel boards for that area

Comments

@inimical719 you would need to backfill with concrete at an angle and put some weep holes in

@inimical719 otherwise the gravel boards will eventually snap

Answer 8

I have got gravel boards retaining a 5ft mound of mud which is about 12ft wide also it was here when I moved in and it is buckling really bad I am in the process of getting rid of it and putting in a concrete wall then I was going to clad it with composite boards to make it look nice
