Board formed concrete material

does anyone know where to get a copy of board formed concrete material?

Loads of websites out there with free textures.
Some allow different resolutions, like this one…
https://www.textures.com/

on there now, thanks

Perhaps try sketchuptextureclub.com?

The second site listed has a really good board formed material. I use both those sites.

This website’s textures aren’t too bad (as well as being completely free): Free seamless textures & wallpapers to download - JPG, PSD, PNG
