250mm Depth Heavy-Duty HDPE Geocell Grid for Steep Slope Stabilization and Erosion Resistance
HDPE Geocell GM356-250mm Geocell for 2:1 Slopes, Vegetation and Soil Retention
GEOMAX® GEOCELL PRODUCT INTRODUCTION
Manufactured from high-density polyethylene, GeoMax® Geocell forms a deep cellular framework that confines soil and aggregate infill. This confinement improves slope integrity by distributing loads evenly and reducing erosion caused by rainfall or surface runoff.
The system is widely applied in slope protection projects where conventional retaining methods are difficult to construct.

APPLICATIONS
 |
SOIL REINFORCEMENTGeomax®(Hdpe Geocell) is the solution to soil stabilization or soil reinforcement. It can increase the bearing capacity of the pavement and avoid cracking of the pavement. |
 |
SLOPE PROTECTIONGeomax®(Hdpe Geocell) is the obvious choice for slope protection or erosion control. It has both good drainage effect and slope protection. |
 |
CHANNEL PROTECTIONGeomax®(Hdpe Geocell) delivers stability and protection of channels |
 |
RETAINING WALLSGeomax®(Hdpe Geocell) offers highly permeable and acts as a great number of planting pots, allowing rainwater to infiltrate, minimizing runoff. |

FAQ:
Q1: Why is a 250 mm cell depth recommended for steep slopes?
Deeper cells provide stronger confinement, improving resistance to soil displacement and erosion.
Q2: Can locally available soil be used as infill?
Yes. Local soil can be used if it meets basic gradation and compaction requirements.
Q3: How does the system handle heavy rainfall conditions?
The cellular structure slows runoff velocity and improves drainage, reducing erosion.
Q4: Is the geocell system compatible with drainage layers?
Yes. It is often installed over geotextiles or drainage layers for enhanced performance.
Q5: Can this system be used on curved or irregular slopes?
Yes. The flexible structure adapts well to complex slope geometries.
