Need ideas for a small retaining wall

[CADplans]

I picked these up from an ad on CraigsList,,,

I will add these to the inlets of my newly installed culverts.

I have only installed one so far,, they are H E A V Y !!,,,

They sell these at precast concrete companies,, I have no idea what they cost new,,,

^^ Shovel some dry Mortar Mix in around the rip-rap while you place it, then more over the top when done. Then spray gently with a garden hose to help it set. That'll stop a lot of the weeds.
