Hydroex Modular Geocellular Unit is designed to provide retention, attenuation and infiltration. All three methods are directed at harvesting and saving rainwater, while recharging the groundwater table and aquifers. The harvested water can then be reused on a day-to-day basis for activities such as gardening, cleaning etc. Its superior surface area and heavy load capacity makes it ideal to manage water run-off at a variety of depths in different areas of applications.
