High mountain roads can be created authentically thanks to the hardfoam series „Rock“. The Rock Wall and the Rock Portals are matching in surface structure and colour and thus they can be combined ideally with each other. The handling of the hardfoam products is very easy. The products can be cut with a knife or a slitting saw and smoothed with a fine rasp. Heated by a hair-dryer you can even form the products. The hardfoam rocks can be fixed with hot-melt adhesive or rock compound on the model landscape.
