Mixed type barriers

In addition to reflective properties, this type of noise barriers refracts acoustic waves by featuring an uneven barrier surface.

• Sawdust concrete noise barriers — a variety of construction solutions allows for the construction of noise barriers with diverse architecture. The surface of sawdust concrete barriers can be covered with polymer and mineral paint resistant to weather conditions and chemicals used on roads.
• Chip concrete noise barriers — these are DBS ribbed chip concrete boards made of a mixture of cement grout and mineralised fragments of coniferous wood, the so-called wood chips. They are harder than sawdust concrete boards and are dyed in any colour.
