It looks like it is a cast in place concrete wall. You can get that look by using our custom concrete board form tiles. They come in 6" x 8' lengths and when installed (easy installation) they give the look of a cast in place piece like this wall. Check out www.2stone.ca and our Facebook page 2Stone Designer Concrete, we have posted some pictures of some fireplaces we have done. I love this wall and the detail of the rocks at the bottom! Very peaceful and organic.
