You can build with these stones: The rigid foam series "Rubble Wall" impresses with its extremely realistic rock structure. The products in this series are ideally suited for constructing buildings in rural settings, such as viaducts or mountain tunnel routes. Most NOCH bridges made from structural rigid foam have the same rock structure as the "Rubble Wall" series. Therefore, the rigid foam bridges and the rigid foam series "Rubble Wall" are perfect to combine. Since our rigid foam items are all hand-painted, color variations are possible. NOCH PROFI structural rigid foam is the perfect material that you will often find with us - and there are many good reasons for this, primarily related to the composition of the material. The raw materials for structural rigid foam are two liquids that are mixed together. This creates a foamy mass that is then allowed to solidify in the desired plastic shape. The resulting products have outstanding properties that are often hard to find in most other materials: they are lightweight yet stable; they are extremely realistic, as our special production technique even allows for undercuts, and they can be very easily processed further.
