From the product name we can know that , Rainwater infiltration tank, is the tank for rainwater infiltration purpose, that means the rainwater will be infiltrated into the ground. Since it is for rainwater infiltration, the water is temporarily stored in the tank, and it will be soaked away slowly as time goes by, so we do not need waterproof geomembrane, we will only need water permeable geotextile to cover the tanks.
