High Strength Geotextiles

Comtrac High Tenacity Polyester Geotextile Reinforcement for embankments
ComtracĀ® polyester geotextiles are comprised of high tenacity polyester yarns woven or knitted into a stable network which allow the yarns to retain their relative positions. High tenacity polyester yarns provide excellent creep resistance which allow for higher tensile strengths at lower stains. The resulting high tensile modulus makes Comtrac polyester geotextiles a natural choice for many earthwork reinforcement applications. Comtrac polyester geotextiles are available in ultimate tensile strengths ranging from 400-6000 lb/in. Comtrac polyester geotextiles conform to the minimum average roll values listed in the following table.

Comtrac High Tenacity Polyester/Polypropylene Geotextile Reinforcement for Walls and Slopes
ComtracĀ® polyester/polypropylene geotextiles are comprised of high tenacity polyester yarns (machine direction) and polypropylene yarns (cross machine direction) woven into a stable network which allow the yarns to retain their relative positions. The superior creep characteristics of high tenacity polyester yarns in the roll direction provide superior long term design strengths (LTDS) at lower strains. The LTDS properties of the Comtrac polyester/polypropylene geotextile provide cost effective alternatives when designing and constructing steepened earth slopes or retaining walls. Comtrac polyester/polypropylene geotextiles conform to the minimum average roll values listed in the following table.

Comtrac Polypropylene Geotextile Reinforcement for roads over soft soils
ComtracĀ® P series high strength geotextiles are comprised of polypropylene yarns woven into a stable network which allow the yarns to retain their relative positions. The geotextile is inert to biological degradation and naturally encountered chemicals, alkalis, and acids. Comtrac P series geotextiles provide a range of ultimate tensile strengths (ASTM D-4595) and were developed to provide stabilization and separation of soft subgrade soils in a variety of construction applications. Comtrac P series geotextiles conform to the minimum average roll values listed in the following table.
