PRODUCT DESCRIPTION

Textured Surface Hdpe 3D Geocell For Bank

Product Introduction

Geocell is also called "cellular confinement systems" academically
.It is widely used in construction for erosion control, soil
stabilization on flat ground and steep slopes, channel protection,
and structural reinforcement for load support and earth
retention.Typical cellular confinement systems are geosynthetics
made with ultrasonically welded high-density polyethylene (HDPE)
strips or PP and expanded on-site to form a honeycomb-like
structure—and filled with sand, soil, rock, gravel or concrete.

Geocell strip widths, hence the on-site height, come in various
sizes from 50 to 300 mm. Geocell walls are usually made from
textured or structured polymer sheet so as to increase frictional
resistance against the infill soil from displacement. Geocell are
made of HDPE, PP, low-density polyethylene and nonwoven heat-bonded
geotextiles. Geocell walls are typically perforated so as to allow
for drainage from one cell to another. On steep slopes Geocell may
have a tendon or cable extending through the central region up the
slope and anchored to, or within, a concrete plinth so as to resist
downgradient sliding of the system. The backfilling of Geocell on
long and wide slopes is quite labor-intensive. Construction
equipment called phneumatic sand-slingers or stone-slingers have
been used advantageously.

Application

SOIL REINFORCEMETN

Geomax®(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 PROTECTION

Geomax®(Geocell) is the obvious choice for slope protection or erosion control. It has both good drainage effect and slope protection.

CHANNEL PROTECTION

Geomax®(Geocell) delivers stability and protection of channels
exposed to erosive conditions ranging from low to high flows, either intermittent or continuous.
