HydroBlox is made from highly porous, high strength recycled thermoplastics designed to filter and direct water flow through surface tension and water pressure. The planks move water from wet areas to dry areas without requiring a downward slope, making them useful for managing groundwater around pool installations and future site developments. HydroBlox maintains permeability, requires little to no post installation maintenance, and can be added to or reused in future projects. For inground pool builds, proper drainage helps reduce standing water around concrete footings, wall panels, and other structural components.
