StormTank® - Model GroundPro™ GRS & GRV -Flexible Permeable Grass & Gravel Paver Systems

StormTank® GroundPro™ GRS & GRV are flexible permeable pavers used in ground stabilization and protection applications. The system’s uniquely engineered design delivers superior load-rating and torsional resistance while the flexible framework allows rolls to be installed easily. GroundPro’s high compressive strength and permeability make it an ideal eco-friendly alternative to impervious paved surfaces while promoting stormwater infiltration, limiting runoff, preventing soil compaction, and reducing heat island effect.

• Pre-assembled rolls considerably reduce install time and cost.
• Rated to far exceed industry loading and durability standards.
• Greatly lessens need for pipes, detention basins, and storm drains.
• Efficient handling of vehicle torsional loads and turning stress.

GRS: How It Works

GroundPro GRS features an open-cell framework that is designed to allow rainfall and stormwater runoff to infiltrate ground-level surface(s), collect within the underlying base material, and then evenly permeate into the subgrade beneath.

GRV: How It Works

GroundPro GRV features an open-cell framework that is designed to allow rainfall and stormwater runoff to infiltrate ground-level surface(s), collect within the underlying base material, and then evenly permeate into the subgrade beneath.

Base Depth Recommendations:

(*) Depth may need to be increased on a case-by-case basis, because of subsoil characteristics, subsoil strength limitations, frost-heave limitations, etc. The engineer shall be responsible for the design and stability of the subgrade and base material.
