These are particularly transformer tubs for petroleum products, retention tanks, tanks of pumping stations, tanks under reservoirs and silos, WWTPs. They are often tanks with complicated shapes. The advantage of the polyurea solution is that it is possible to copy the shape of the retention tank fully and in detail and the work is relatively quick.
From the viewpoint of material used, we distinguish retention tanks for acids , where a material relevant for the chemical load must be used. In case of need we also use materials for heavy chemical load .
