Permeable Grass Pavers & Porous Paving

Yes, in most applications, grass pavers and geocell-based porous paving systems are more cost-effective than concrete. They require less material, reduce aggregate usage when paired with nonwoven geotextiles, and lower installation labor costs. They also reduce long-term maintenance expenses by controlling erosion and maintaining subgrade strength over time.

Cellular confinement grass pavers should not be laid directly on unstabilized or weak subgrade without proper preparation. A geotextile fabric is typically installed beneath the geocell layer to separate soil from fill material, prevent migration, and improve load distribution. Proper subgrade assessment — including DCP testing and CBR evaluation — ensures long-term performance and stability.

Permeable grass pavers using cellular confinement technology are well-suited for driveways, parking lots, nature and bike trails, sports fields, emergency vehicle access areas, and sloped embankments. They provide structural reinforcement while maintaining a vegetated or aggregate surface, making them ideal for both light and heavy-load applications.

Cellular confinement systems confine soil and aggregate particles within their interlocked cell walls, preventing displacement from water flow, foot traffic, or vehicle loads. This confinement reduces surface runoff velocity and erosion on slopes, channels, and embankments. When filled with vegetation or rock, they also absorb surface water and reduce scour on vulnerable land areas.

Geocell grass pavers are typically manufactured from high-density polyethylene (HDPE) strips or Novel Polymeric Alloy (NPA), welded together to form a three-dimensional honeycomb structure. Fill materials can include soil, aggregate, or a combination of both. HDPE provides excellent durability, UV resistance, and long-term structural performance in permanent outdoor installations.

Yes, cellular confinement systems are highly effective on steep slopes. Their geocell structure forms a large interlocked mat that anchors fill material in place, resisting displacement even under heavy rainfall or load stress. They are commonly used for slope stabilization, embankment protection, and channel lining where traditional paving methods are impractical or cost-prohibitive.
