Commonly known simply as HydroBlox, these planks are a permanent solution superior to traditional drainage, stabilization, and green infrastructure systems for a wide range of industries. The product’s high-void structure allows for a drainage capacity and structural stability greater than stone or pipe. Fast and easy to install, HydroPlanks use water pressure to redirect stormwater in any direction, without clogging. When installed either vertically or horizontally, there is no need to connect the planks, however they do need to be touching. However, when additional stability or continuous surface area of HydroBlox plank is required, such as in creating a permeable pavement sub-base or a trafficking surface, connect the planks with landscape spikes. Extremely versatile, HydroPlanks can be retrofit to traditional drainage systems by connecting with a HydroBlox Transition Box
