GEOTEXTILE FELT

NON-WOVEN POLYESTER AND POLYPROPYLENE FELT

DEFINITION:

Geotextile is a non-woven product manufactured by combinining synthetic short yarns mechanically by using needling method. Non-woven geotextile has no woof and warp. Strength is achieved by combining yarns and applying thermal process. Geotextile felt is a permeable textile product which can be used with basic elements or with any material related with soil, running ground or geotechnic engineering.

USAGE AREAS:

Used in motorways, sport facilities, tunnels and underground facilities, art buildings, underground, agricultural areas, garden terraces, airports, mining fields, railways, solid waste storage areas, irrigation channels and reservoirs, shore protection and isolationareas; as a reinforcementagainst cracks between insulationlayers; as a separator between waterproofing and thermal insulation layers; to protect insulation; to drain excess water; to prevent drainage pipes from plugging by wrapping them around; to avoid sinking and in many other applications.

TECHNICAL SPECIFICATIONS:

ADVANTAGES:

Thanks to thermal process, more strength and less elongation is achieved with the same weight.

Requires smaller storage area.

Can be manufactured up to a width of 6 meters, leading to less loss of material.

Both white and tinted varieties of ge0textile are manufactured from 100% pure yarn. No recycled material is used.

Products can be manufactured with surface weight ranging from 50 gr/m2 to 1000 gr/m2.

APPLICATION:

Various applications:

- in liquid bituminous insulation applications, it is used as a reinforcement between layers and avoids cracks.

- it prevents cracks found on the surface from moving onto insulation surface.

- it protects bituminous membrane or geomembrane applications in foundations.

- it is used as a separator between waterproofing and thermal insulation layers.

- it is used as a separator between thermal insulation and protection layers.

- It is wrapped around drainage pipes in foundations and it is used as a filter layer in terrace gardens.

- It is used in applications designed to withdraw pressure under road coatings.

COVERAGE RATE:

Calculation of coverage rate :

Coverage rate = area x ( roll width + overlap ) / roll width

Example:

1500 m2 area, 3 meters width, 20 cm overlap

1500 m2 x ( 3,00 m + 0,20 m )

= 1600 m2 geotextile required

3,00

PACKAGING:

Depending on the weight, geotextile felt is packed with various length options.

Examples:

50 gr/m2 ------ 1,5 m * 400 m = 600 m2/roll
100 gr/m2 ------ 2,5 m * 100 m = 250 m2/roll
150 gr/m2 ------ 2,5 m * 100 m = 250 m2/roll
