Introduction

HDPE Geocell is a popular new type of high strength geoynthetic material, which is a three-dimensional mesh cell structure made of high tensile strength HDPE sheets welded by high strength ultrasonic waves. It can be stretched freely, folded for transportation, drawn into a network during construction, unfolded into a honeycomb three-dimensional grid, filled with loose materials such as soil, gravel, concrete, and so on, to form a structure with strong lateral restrictions and large stiffness.

Properties Of HDPE Geocell

*Flexible, transport can be folded

*Light material, wear resistance, stable chemical properties, light oxygen aging resistance, acid and alkali resistance

*High side limit and anti-slip, anti-deformation, effectively enhance the bearing capacity of the roadbed and disperse the load

*Change the height of the geoglage chamber, welding torch and other geometric dimensions to meet different engineering needs

*Flexible, small transportation volume, convenient connection, fast construction speed

Advantages Of HDPE Geocell

*Time and labor savings

*Durable and long service life

*All season and all weather condition

*Green product

*Environment friendly

*Reduces loose of top soil

*Limits the erosion quantity

*Provides planting and vegetable surfaces

*Aesthetical surfaces

*Economical and fast landscaping possibility

*Easy to install with mechanical anchoring

*Self drainage capability 

Application Of HDPE Geocell

*Highway and railroad side slopes

*Lagoon and channel shore slopes

*Dry channel bottoms and side slopes

*It is used to stabilize the railway roadbed

*It is used to stabilize highway subgrade

*Levees and retaining walls for bearing loads

*It is used for shallow water river treatment

*It is used to support pipes and sewers

*Hybrid retaining wall with load force for preventing landslide

*It is used for independent walls, wharves, breakwaters, etc

*It is used for desert, beach and riverbed, river bank management
