Grass Reinforcement Grids

Product Definition

Grass Reinforcement Grids are load-bearing cellular pavement systems manufactured from polymer or concrete composites, designed to stabilize turf surfaces while distributing traffic loads, preventing soil compaction, and enabling sustainable permeable ground solutions for light to heavy vehicular use.

Industry Comparison

Application Scenarios

• Emergency vehicle access routes

• Parking lawns and overflow parking zones

• Golf cart paths and resort landscaping

• Fire lanes in commercial and residential developments

• Slope stabilization and erosion control systems

Core Pain Points and Engineering Solutions

• Soil Rutting Under Traffic: Cellular structure disperses wheel loads evenly

• Poor Drainage and Waterlogging: High void ratio enables rapid infiltration

• Vegetation Damage: Protective grid walls shield root zone from shear forces

• Ground Settlement: Grid-reinforced layers reduce long-term deformation

Risk Warnings and Mitigation Recommendations

• Risk: Inadequate subbase compaction
  Mitigation: Minimum 95% Proctor density before grid placement

• Risk: Grid uplift during freeze-thaw cycles
  Mitigation: Use geotextile separation and proper drainage layers

• Risk: UV degradation in storage
  Mitigation: Store under UV-protective covers before installation

• Risk: Vegetation failure
  Mitigation: Select grass species compatible with traffic load and climate

Procurement and Selection Guide

1. Define traffic load class and axle load requirements

2. Assess subgrade CBR value and moisture conditions

3. Select cell height based on design load and soil bearing capacity

4. Verify polymer grade and UV stabilization package

5. Request compressive and creep resistance test reports

6. Confirm interlocking compatibility for large-scale installation

7. Evaluate packaging efficiency for logistics and site handling

Engineering Application Case

In a municipal overflow parking project of 9,500 m², Grass Reinforcement Grids with 40 mm cell height were installed over a compacted crushed stone base. The system was designed for occasional heavy truck access. Post-installation monitoring over two rainy seasons showed stable load performance and consistent turf coverage without visible rutting.
