The clear water plywood is made of pine, eucalyptus and other boards. The surface is impregnated with highly waterproof phenolic resin and pressed at high temperature to form a wood plywood formwork. Its surface is smooth and flat. The concrete poured with this formwork is named “clear water formwork” because of its smooth surface. It is mainly suitable for formwork of shear walls, vertical wall panels in high-rise buildings, dams, tunnels, overpasses, arch bridges, bridges, beams and columns, etc.
