Bases and undergrounds

Bases and undergrounds

Every layout starts below the surface: foam sheets and blocks to carve, plaster cloth and strips to shape the relief, preformed inclines and declines that guarantee even grades, Track-Bed underlay and rigid panels for diorama bases. These light, easy-to-work materials give your hills, valleys and rights-of-way a solid foundation — and forgive changes of mind along the way. Back to the Terrain collection.
