Protecting Every Surface, Inside and Out.
Product
Strip-type geosynthetic reinforcement is a linear composite material
designed to ensure the stability of mechanically stabilized earth (MSE)
walls and reinforced slopes. This reinforcement is installed within soil,
utilizing frictional resistance and tensile strength between the soil and
the reinforcement to prevent shear failure and provide internal stability
to the structure.
It was developed to overcome the shortcomings of conventional
galvanized steel strips, which are vulnerable to corrosive environments
such as seawater and acidic soils. This product combines the tensile
performance of high-tenacity polyester (HTPET) fibers with the chemical
durability of polyethylene (PE) coating, offering superior strength and
long-term resistance.

long-term resistance.
Strip-type geosynthetic reinforcement consists of a dual structure comprising an inner core that supports the load and an outer sheath that protects it.
1. Inner Core: Super High Tenacity Polyester (SHT PET)
Function
It provides the tensile force caused by earth pressure acting on the structure.
Structure
Thousands of high-tenacity filaments are arranged as parallel fibers without twisting, resulting in low strain under tensile loading and delivering high-strength performance.
Chemical properties
To ensure long-term resistance to hydrolysis, yarns are typically selected with a molecular weight (Mn) of at least 25,000 g/mol and a carboxyl end group (CEG) content less than 30 mmol/kg.
2. Outer Coating: Polyethylene (LLDPE Sheath)
Function
The outer coating provides complete isolation and protection of the internal core from acids, alkalis, salts, and physical damage during installation.
Shape
The outer coating is extrusion-molded into strip shapes with a width of approximately 50 to 90 mm, and its surface features fine textures or ribs to maximize frictional interaction with soil.
Channel Structure
Inside the coating, discrete channels are formed to prevent the internal fibers from clumping, ensuring that stresses are evenlydistributed throughout the material.
