HydroBlox Planks


Commonly known simply as HydroBlox, these planks are a permanent solution superior to traditional drainage. The HydroPlanks are used for a variety of water management problems. 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 crushing or clogging. 
When installing either vertically or horizontally, the planks have to be touching or connected with stainless steel screws. 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
