STRATA GLOBAL

OVERVIEW

Adaptability designed for the future

StrataTex HSR is a next-generation flexible polyester high-performance geotextile used in soil reinforcement and other civil engineering applications. StrataTex HSR is manufactured using a high-grade polyester yarn with special high tenacity and low creep properties knitted into a stable network.

It is differentiated from other geotextiles by lower elongation, superior stress-strain values, and high permeability performance. It has wider widths (up to 5.8m) and customised lengths for efficient and cost-effective usage.

MANUFACTURING

How it’s made?

StrataTex HSR is manufactured in the state-of-the-art manufacturing plant located in India.

The manufacturing process involves 2 phases:

stratatex beaming
Beaming

A predetermined number of yarn ends are pulled from a creel and are wound onto a large cylindrical beam. We have fully automated, highly sophisticated beaming machinery, which ensures uniformity in yarn tension and take-up and unwinding stability.

Knitting

Using state-of-the-art knitting machines, high tenacity Polyester yarn is precision-knitted into a dimensionally stable network of apertures.

APPLICATIONS

Where can StrataTex HSR be used?

We guide engineers, contractors, and owners to use StrataTex HSR to achieve cost effective, sustainable, and reliable solutions for various site development challenges.

Embankment over soft soil
Basal reinforcement for embankments on soft soil

Embankments over soft soil need basal stabilization during construction and until the foundation soil gains sufficient shear strength due to consolidation. Basal reinforcement distributes the load over a wider area and provides resistance against shear failure due to tensile strength improving the safety against bearing and shear failure of the embankment. Here, StrataTex HSR caters to two applications: (1) Separation (2) Reinforcement. A separator is required in the basal reinforcement system consisting of geosynthetic reinforcement and granular fill, to avoid mixing and loss of granular fill within the soft layer. StrataTex HSR separates and reinforces simultaneously, eliminating the need for an additional layer and reducing the cost and installation time.

Pavement Stabilization
Paved and unpaved roads

Pavements that are to be constructed on expansive or slushy soils with soft clay as subgrade, need a strong long-lasting separator above subgrade to ensure performance over the service life of the pavement. Using StrataTex HSR on subgrade not only provides the separation required but also improves the modulus of the granular layer above subgrade owing to its tensile modulus. StrataTex HSR, when placed above subgrade, improves the modulus or layer coefficient of the granular material above by reinforcing that layer based on friction, interaction, and tensile strength properties of StrataTex HSR. StrataTex HSR possesses excellent permeability and strength compared to nonwoven geotextiles which cater to a higher flow of water, ensuring serviceability performance of the pavement.

Load transfer platform for piled embankments

Embankments constructed over piles, on soft ground, need a load transfer platform with basal reinforcement spanning across pile caps to ensure the transfer of embankment loads onto the piles. Using StrataTex HSR ensures separation and tensile strength provision to the load transfer platform system catering to both separation and reinforcement in one geosynthetic layer. It ensures smooth load transfer from the embankment to the pile caps providing the required serviceability to the embankment without excessive deformations in the region between pile cap spacing. With proper design of basal reinforcement using StrataTex HSR, the pile cap size and pile spacing design can be optimized to ensure economy along with safety. These load transfer platforms are designed in line with international guidelines such as British Standards and FHWA (Federal Highway Administration) in the USA.

CASE STUDIES

Some of our greatest hits with StrataTex HSR

Making way on the Pune-Solapur Highway

The National highway approaches were constructed with the reinforced soil (RS) wall system to retain the earth instead of the conventional RCC retaining walls and proved to be cost effective and faster to construct.

QUALITY TESTING

How long does it last?

Many design engineers face challenges finding geosynthetic reinforcements that meet quality standards. The long-term performance of a geotextile is dependent on several factors such as raw materials used, the manufacturing process adopted, the designs, and the end application.

Since geotextiles are used for critical designs, it is essential to have a clear understanding of the above factors. To meet those standards, StrataTex HSR undergoes exhaustive testing at internationally reputed laboratories to define all of the above factors.
