TechStrap Geostrips are geosynthetic strips (polymeric strips/straps with a flat webbing like structure) specifically engineered for the reinforcement of soils and other fills for the construction of reinforced soil or mechanically stabilized earth structures. TechStrap Geostrips comprise a core of closely packed and tensioned high tenacity polyester filament yarn tendons encased in a sheath of linear low density polyethylene.
The polyester yarn tendons are the load-carrying elements and comprise select high tenacity polyester filament yarns with high tensile strength and modulus, low creep, high molecular weight (> 25,000 g/mol) and low carboxyl end groups (< 30 mmol/kg) to ensure excellent performance and durability.
The sheath consists of a custom formulation of superior grades of linear low density polyethylene and additives to enhance resistance to ultraviolet rays. The composition and thickness of the sheath is specifically engineered to provide a high level of dimensional stability and protection from weathering and exceptional resistance to installation damage. The surface texture of the sheath ensures a high degree of frictional interaction with the fill to mobilize high pullout resistance.
TechStrap Geostrips are available with tensile strength of 30, 40, 50, 75 and 100 kN
