Landfill

– Seepage prevention

Geomembranes play a vital role in landfills. For example, high-density polyethylene geomembranes can effectively prevent landfill leachate from seeping into groundwater bodies and prevent groundwater pollution. Its low permeability and high chemical stability can provide a reliable bottom and side wall seepage barrier for landfills.

– Gas collection:

Geocomposite drainage nets can be used in the gas collection system of landfills. It can smoothly discharge gases such as methane produced by garbage decomposition, which can not only prevent gas accumulation from causing explosion hazards, but also make reasonable use of the collected gases, such as power generation as energy.

Contaminated land remediation

– Isolation of pollutants:

Geotextiles can be used to isolate contaminated soil from the surrounding environment. When a piece of land is contaminated by heavy metals or organic matter, geotextiles can prevent further spread of pollutants, thereby controlling the scope of contamination.

– Auxiliary remediation process:

In some contaminated sites using chemical or biological remediation methods, geotextiles can be used as carriers or auxiliary materials. For example, in bioremediation, geotextiles can fix microorganisms to better decompose pollutants in the soil.

River management

– Riverbank protection:

Geogrids and geotextiles can enhance the stability of riverbanks. In some riverbanks prone to soil erosion, laying geogrids and planting vegetation can effectively prevent riverbank collapse and protect the river’s ecological environment.

– Filtration and purification:

Geotechnical products can be used as a filter layer to purify river water quality. For example, a geotextile filter device is set up in the river, which can filter out suspended particles, some organic matter and heavy metal ions in the water, and improve the quality of river water.
