What drainage for retaining wall along fence?

[paula24]

Hi

I am wanting to level block in backyard.  Putting 2 sleepers high retaining wall 400 high along fence line. 

Do I need to worry about drainage or what type of rocks can I put in between retaing wall and fence. Gap will be aprox 250 to 300

Sorry for all questions.  I just noticed that these are too low for amount of soil we need. Are they easy to lift them up. I have attached pictures. And imbues what do I need.

Thanks

Hi @paula24,

It is easy to raise the level of the inspection outlet so it is flush with your new level. However, to do so would be considered plumbing work and requires a licensed plumber. I'd imagine it wouldn't be too expensive to have done, as it only requires minimal work.

Oh ok. I was hoping landscaper can do it. He didn't mention anything to me.
