concret wall

I am building a cross road defense position from the Sicily campain. What is a good thing to use for a concret wall???

A thin piece of wood, covered in a thin layer of plaster or drywall compound. It looks pretty realistic. If adding battle damage–just use a motor tool (like a Dremel) and just nick it against the dried plaster where you want the bullet or fragment damage.

Sculpey clay…

Here’s a few pics of a 1/35 war torn European cottage diorama I started but never finished; walls were made from Sculpey, and the wood beams were made from popsicle sticks…
