HAOYANG HYE series Geotextile Ecological Bag (Slope Bag, Afforest Bag) can be applied in slope engineering, completely replacing the stone, cement and other materials, to significantly reduce cost of project. After construction, slope will be covered by vegetation surface, to enable a green excavated slope surface, and formation of slope of natural ecology. Permeability through soil filtering, allows slope to be highly permeable, to prevent and stabilize soil loss, the local landslide, slope collapse greatly, to form a permanently high stability natural slope.

Size Calculation Formula for Geobag (Slope Bag, Afforest Bag) Filled with Soil

Length = length of Geobag (Slope Bag, Afforest Bag) - (12-15) cm
Width = width of Geobag (Slope Bag, Afforest Bag) x 0.7 cm
Height = height of Geobag (Slope Bag, Afforest Bag) x 0.4cm

In addition to a high corrosion resistance, ultraviolet resistance, and aging resistance, the geobag (slope bag, afforest bag) is also resistant to combustion and pests, toxin free, non-combustible and stable. It also will not be affected by chemicals in the soil, or rot, due to its outstanding physical and water-penetration performances that are highly reliable and praised by our customers. With the addition of moisture resistance materials that do not absorb water, do not damage or otherwise cause deformations in the bag, this bag can be used in even the most polluted water.

Advantage of Geobag

Geotextile ecological bags (Slope Bag, Afforest Bag) are an important component for flexible ecological slope engineering systems, with filtering functions for objective-water penetration and soil conservation in order to prevent the loss of fillings (mixture of soil and other nurseries), and to maintain a normal exchange of moisture in the soil. This reduces the hydrostatic pressure of the slope, while simultaneously maintaining effective and timely replenishment of the water needed for plant growth in order to maintain media required for vegetation life. Geotextile ecological bags (Slope Bag, Afforest Bag) are made from environment-friendly materials to allow the plant to grow freely through the bag. Roots enter the engineering foundation soil, anchoring the plant between the ground and the bag (the longer the roots, the stronger they are) in order to ensure a greater degree of permanence in a slope by preventing erosion, and thus, reducing maintenance costs.

Geotextile ecological bags (Slope Bag, Afforest Bag) are widely used in slope engineering, to completely replace stone, cement and other materials in order to significantly reduce project costs. After construction, the slope will be covered by a vegetation surface, in order to allow the slope formation to follow natural ecology without erosion. Permeability through soil filtering allows the slope to be highly permeable which prevents and stabilizes soil loss, thus preventing landslides, erosion or slop collapse, and instead, offering a highly stable, solid, natural slope.

Production Process of Geobag

HAOYANG HYE series geotextile ecological bags (Slope Bag, Afforest Bag) are made from Polypropylene (PP) or Polyester Fiber (PET), by ironing a needle-punch non-woven fabric on both sides through special processing.
