That wall looks like a concrete poured in place structure. We have created a few products that can be used to achieve this look where it was not previously possible. Our product is concrete not another material trying to look (and feel) like concrete, it's strength comes from the glass fibre that is in our mix, we can create very large thin pieces that have incredible strength. Check out the tiles (72" x 6" x 1/2 - less then 20 lbs) and our panels (36" x 48", only 55 lbs). For more information contact me at lise@2stone.ca
