About

100% Permeable

Our grids are designed to be 100% permeable, effectively eliminating puddles and ruts and significantly reducing the burden on stormwater management systems.

About

Heat welded geo-textile

We stand alone in offering an innovative, non-rotting, heat-welded geo-textile. This advanced fabric not only secures the gravel within the cell to prevent bulging by barring gravel migration underneath but also adeptly suppresses weed growth from below, ensuring a clean, maintenance-free surface.

About

Worlds only grid system for steep slopes

Our company exclusively provides a grid tailored for sloped applications, setting us apart in the industry. The 60-40 grid, with its innovative lateral drainage design, ensures seamless water flow between cells, effectively preventing any accumulation on slopes. Additionally, the grid is equipped with dedicated slots for inserting 8-12 inch galvanized nails, anchoring the grid firmly in place and virtually eliminating slippage risks. This combination of efficient drainage, secure anchoring, advanced geo-textile, and hexagonal design culminates in a foundation of unmatched permeability and stability.
