Product Description

Geotextile

Geotextile Fabrics - the oldest and most commonly used geosynthetic today - are engineered to provide cost-effective solutions to meet specific design requirements. And although there are at least 80 specific 'applications' for geotextiles that have been developed, a geotextile always performs at least one of five discrete 'functions':

--Separation

--Reinforcement

--Filtration

--Drainage

--Protection

Geotextiles are synthetic and permeable materials used in civil construction projects to improve soil characteristics. Geotextiles make poor soils more suitable for construction, since they have the ability to separate, filter, reinforce, protect and drain soils.

Geotextiles are useful in many infrastructure works such as roads, landfills, harbors, drainage structures and other civil engineering projects.

Types of Geotextiles that we can do

Geotextiles are made from polymers such as polypropylene and polyester. They are divided into three categories, according to their manufacturing process::

Woven fabric

Nonwoven fabric

Knitted fabric

Geotextile Separation

This is the main reason why geotextiles are used in construction. When a geotextile is installed between two different soils, it will prevent intermixing when water gets into the soil strata. This way, the required soil characteristics can be conserved. By separating fine subgrade soil from the aggregates, which is the case of roads, the geotextile preserves the drainage properties and strength of the base material.

These geotextiles have special thickness and permeability properties, to prevent soil contamination and to allow water flow without compromising structural integrity. Some application areas of geotextiles include:

Between landfills and stone base courses

Between subgrade and base in paved and unpaved roads

Between subgrade in railroads

Between geomembranes and sand drainage layers
