Sunjüt Geotextiles are also available UV-stabilized with woven-in loops, long life additives antioxidants for under water applications, with loop holes, flame retardant and coated/laminated. We can weave up to 900 g/m²
SUN GEO is engineered to provide cost-effective solutions and to meet specific design requirements in separation, reinforcement, filtration, drainage, and cushion applications.
SUN GEO is applied for reinforcement structures, such as mechanical stability earth walls, reinforced slopes, reinforced embankments, soft foundation improvements and other geotechnical engineering applications for increasing soil shear strength.
SUN GEO have been used in a wide range of applications such as pavements/roads/railroad beds/airfields, retaining wall earth embankments, concrete revetments, drain construction waterways, as well as coastal engineering and defense structures, industrial and contaminated land reclamation and landfills – to either increase the life of the pavement or reduce cost.
The placement of SUN GEO between the soft subgrade and the granular material may provide one or more of the following functions,
- a filter to allow water but not soil to pass through it,
- a separator to prevent the mixing of the soft soil and the granular material,
- a reinforcement layer to resist the development of rutting and difference settlement.

EN 13251 Earthworks, foundations and retaining structures Geotextiles are normally placed between the subgrade and ballast layer or between the subgrade and subballast layers if one is present. A common geotextile application is found in what is commonly known as “pumping track” and “ballast pocket areas |

EN 13254 Erosion and Sediment Control (construction of reservoirs and dams) Erosion is caused by a group of physical and chemical processes by which the soil or rock material is loosened, detached, and transported from one place to another by running water,waves, wind, moving ice, or other geological sheet and bank erosion agents. In erosion control, the geotextile protects soil surfaces from the tractive forces of moving water or wind and rainfall erosion. Geotextiles can be used in ditch linings to protect erodible fine sands or cohesionless silts. |

Filtration and Drainage Control of water is critical to the performance of buildings, pavements, embankments, retaining walls, and other structures. The use of geotextiles in filter applications is probably the oldest, the most widely known, and the most used function of geotextiles. In this application, the geotextile is placed in contact with and down gradient of soil to be drained. Drains are used to relieve hydrostatic pressure against underground and retaining walls, slabs and underground tanks and to prevent loss of soil strength and stability in slopes, embankments, and beneath pavements. When functioning as a drain, a geotextile acts as a conduit for the movement of liquids or gases in the plane of the geotextile. Examples are geotextiles used as wick drains and blanket drains. |

Reinforcement Quite often, conventional construction techniques will not allow dikes or levees to be constructed on very soft foundations because it may not be cost effective, operationally practical, or technically feasible. In the most common reinforcement application, the geotextile interacts with soil through frictional or adhesion forces to resist tensile or shear forces. To provide reinforcement, a geotextile must have sufficient strength and embedment length to resist the tensile forces generated,and the strength must be developed at sufficiently small strains (i.e. high modulus) to prevent excessive movement of the reinforced structure. |

Separation (Reinforced Solid Walls) Separation is the process of preventing two dissimilar materials from mixing. In this function, a geotextile is most often required to prevent the undesirable mixing of fill and natural soils or two different types of fills. Geotextiles have been utilized in the construction of reinforced soil walls since the early 1970’s. Geotextile sheets are used to wrap compacted soil in layers producing a stable composite structure. In the most common reinforcement application, the geotextile interacts with soil through frictional or adhesion forces to resist tensile or shear forces. To provide reinforcement, a geotextile must have sufficient strength and embedment length to resist the tensile forces generated,and the strength must be developed at sufficiently small strains (i.e. high modulus) to prevent excessive movement of the reinforced structure. |
| Moisture Barrier Woven geotextiles can serve as moisture barriers when impregnated with bituminous, rubber-bitumen, or polymeric mixtures. Such impregnation reduces both the cross-plane and in-plane flow capacity of the geotextiles to a minimum. |
