SOIL-BASED BARRIERS
Soil-based barriers are a load-bearing structure in which the load-bearing elements are steel frames placed on a specially prepared base, screwed together with screws and tie rods. The installed steel frame is lined with mats from the inside and covered with earth and aggregate. The soil to be backfilled may come from the construction site.
They constitute the most effective soundproofing for direct noise propagation.
The galvanized steel structures produced by our company for the construction of earth screens are free-standing, self-supporting steel modules filled with earth and aggregate, constituting an anti-sound shield for the direct transmission of traffic and industrial noise in the air.
