Associated ISRNM partner SIA „Composite Constructions” (CC) in January 2014 started blocks production for anti-noise barrier. The composite blocks for noise protection walls construction are produced by the original technology in new equipment, which was designed in Latvia and produced in China after the international procurement tender.

The blocks producing technology is made especially for sound absorption. The ingredients of the blocks contents used only fibres and the organic parts. Acoustic characteristics and endurance tests are inspected in the laboratory. Tests have shown that blocks provide good sound adsorption and mechanical properties. That is very important for the wall construction. In addition, the material is environmentally friendly, because these bricks are fully recyclable after their service life.
