Double-walled
The innovative design combines the advantages of plastic and concrete, while also serving as a support for the reinforcement for the future concrete intermediate layer. The plastic walls provide perfect protection for the concrete structure against the aggressive effects of wastewater and groundwater. As a result, the tank acquires the static properties typical of concrete tanks, such as load-bearing capacity and resistance to soil pressure and travel loads. This combination of materials and structural elements ensures the reliability, durability and longevity of the tank in demanding conditions.
