PaveDrain Design Objective

The stone reservoir immediately beneath the PaveDrain System is ¾" clean angular stone (#57 Stone) with no fines. The depth of this first stone reservoir beneath the PaveDrain System ranges from 4”-12" based on the soil conditions, anticipated loading and storm water volumes. Additional stormwater storage can be achieved by adding an additional layer of larger diameter stone (ASTM #2 or #3 Stone; 2"-3") to the required depth.

A geogrid or woven monofilament geotextile layer is STRONGLY recommended below the bottom layer of stone to maintain a clean stone reservoir and enhance structural stability. Please contact PaveDrain, LLC for geosynthetic recommendations.

Void space for stone varies from 30% on ¾" clean stone and up to 40% for 2-3" clean stone. The void space will vary depending on your local and or regional regulations.

PaveDrain, LLC will provide a layout of the project identifying all of the appropriate styles of PaveDrain blocks. (i.e. Arched, Solid, Half and End). We will also give a total block count and area of coverage so that all parties know precisely what is going to ship.

PaveDrain permeable paving supported by HydroCAD

HydroCAD-10 provides direct support for the PaveDrain system of permeable articulating concrete blocks. This allows the storage and infiltration capabilities of PaveDrain installations to be easily modeled with HydroCAD. www.HydroCAD.net

The PaveDrain can be modeled with HydroCAD-10, which provides an interactive chamber wizard for easy layout, pricing, and modeling of modular storage systems.
