What is the difference between landscape fabric and geotextile?
Landscape fabrics and geotextiles are both materials used in civil engineering and landscape design, but they have some key differences. Here are the main differences between landscape fabrics and geotextiles:
Purpose and functions:
Landscape Fabric: Landscape fabric is primarily used for landscaping and soil protection. It is commonly used in lawns, gardens, landscape beds, and more to help control weed growth, protect soil from erosion, and maintain soil moisture.
Geotextiles: Geotextiles are primarily used in civil engineering and soil engineering, including anti-seepage, isolation, reinforcement and layering applications. Its functions include preventing water penetration, separating different soil layers, strengthening the soil, and preventing erosion.
Material and structure:
Landscape Fabric: Landscaping fabric is typically made from textile materials, such as polypropylene or polyester, and has an open fabric structure to allow moisture and air to penetrate.
Geotextiles: Geotextiles are usually made of polyethylene (PE) or polypropylene (PP), and their structure is usually a tightly woven or synthetic film with good waterproof and isolation properties.
Thickness and Strength:
Landscape Fabric: Landscape fabric is typically thin, relatively low-strength, and suitable for light-duty applications.
Geotextiles: Geotextiles are generally thicker, have high tensile strength and stiffness, and are suitable for applications in civil engineering that need to withstand larger loads.
Application areas:
Landscape fabric: Mainly used for landscaping, gardening and soil protection, such as gardens, flower beds, landscape construction, etc.
Geotextile: Mainly used in civil engineering and soil engineering, such as road construction, water conservancy projects, river embankment repair, landfills, etc.
In general, landscape fabrics and geotextiles have different uses, materials, and structures, so the selection of materials needs to be based on the specific project or landscape design needs.

Is geotextile high density polyethylene?
Geotextiles are typically not made from high-density polyethylene (HDPE), but from materials such as polypropylene (PP) or low-density polyethylene (LDPE). Although HDPE has uses in some geotechnical applications, it is generally used to make impermeable membranes rather than geotextiles.
The materials geotextiles are made from can vary depending on the manufacturer and specific application, but a common choice is polypropylene. This is because polypropylene has high tensile strength, chemical resistance and weather resistance, making it suitable for isolation, reinforcement and protection applications in geotechnical engineering. Low-density polyethylene (LDPE) can also be used in some geotextiles, but is typically used in lighter-duty applications because of its relatively low strength and chemical resistance.
In summary, geotextiles are typically not made from high-density polyethylene, but rather from polypropylene or other synthetic materials suitable for geotechnical needs.
