Foam plastic with decoration like brick?

[larsu]

Hi!
Time for the next project . I'm going to cast a retaining wall in concrete and to make it look nice, I was thinking of using foam with decor resembling brick. This decor can be found on bridges, etc. But I can't find any supplier of this. I would be very grateful if someone on the forum could give tips and info on where to buy this type of foam.

Thanks in advance
