In case of a larger amount of wastewater and solid agents, we need more space to store them, such as lagoons or depots. We make lagoons and depots from geomembranes made from high density polyethylene (HDPE), with different thickness and smoothed or rough surface. The geomembrane foil is very persistent, and chemically and UV resistant. We can manufacture different types of lagoons, depending on the usage, such as waste depots, tanks for different types of water, the accumulation of waste and rain water, and any other place where the achievement of watertight layer is needed.
