Erosion Control

Geotextile in Erosion Control

Woven geotextiles are used as integral components in the design and construction of a variety of Coastal structures such as revetments, breakwaters, Sea walls, Anti Sea Erosion bunds and other containment structures. The materials used are easy to install beneath the water surface, and can provide long-term performance.

REVETMENTS

A Woven Geotextile acts as a filter underneath revetments to prevent the erosion of soil. The protection on top of the can be a wide range of materials such as rock, gabions and mattresses, concrete blocks, boulders etc. Applications range from riverbank protection to coastal protection works.

BREAKWATERS

Our product can also be used as a filter at the base of rubble-mound breakwaters. In this location, the Woven geotextile prevents the erosion of the base soil through the granular layers in the breakwater. In some cases, the Geotextile may also be required to reinforce the base of the breakwater when it is constructed on soft soils.

SHORE PROTECTION

High Strength Woven geotextiles are used in construction of Containers such as tubes, bags, etc which serve as shore protection structures. These measures prove effective in dissipating wave energy. These products are highly flexible and very economical since they utilize locally dredged materials.

Silt Fence

Is a geotextile specifically designed to offer a combination of UV resistance, strength, and hydraulic properties for use in sediment control applications.
Silt Fence is a woven polypropylene geotextile containing a combination of monofilament and fibrillated yarns designed to filter out sediment while reatining a high flow rate without clogging. Typically the product is fastened to wooden or metal posts. The preferred method is to use a specially designed ditch digger which installs the product and compacts the ground in one operation. Contact us for further information regarding this type of machinery.

When properly installed, silt fence geotextiles assist to control sediment laden runoff from disturbed areas. These fabrics help contain overland flow and filter suspended soil particles from water, preventing environmental damage to areas adjacent to construction sites. As sediment accumulates, silt fence geotextile’s high tensile strength and low maintenance features allow continued excellent performance until vegetation is complete.

Silt fences help protect streams, rivers, lakes, and reservoirs from contaminaton by sediment. Runoff from stormwater and other “non-point” sources is one of the largest remaining unaddressed sources of water pollution.

Gabions

Soil erosion is a common problem and Gabions have proved to be a lasting solution around the world.

TechFab Gabions are box type structures made from polymer ropes similar to the conventional metal/ wire crate type of Gabions. Gabions made from polymer ropes have certain advantages especially in marine environment where they would be in constant contact with water. Polymer Rope Gabions will not rust or corrode.

The lasting appeal of Polymer Rope Gabions lies in their inherent flexibility. These Gabion structures yield to earth movement but maintain full efficiency and remain structurally sound due to their ability to adjust to the bed contour. They are unlike rigid or semi-rigid structures, which may undergo failure even when slight changes occur in their foundations.

Gabions are used for several applications such as:

Anti Sea erosion bunds, Revetments, Sea Walls, Riprap, etc.

We've challenged conventional Gabion design to create a strong, flexible, dimensionally stable product, which assembles quickly and easily.
