In various recreational site renovation projects, geotextiles have become an indispensable core material due to their excellent isolation and protection properties. Many old recreational sites, due to long-term use, suffer from mixed soil and slopes prone to soil erosion, causing numerous problems for renovation work. High-performance, cost-effective geotextiles can serve as a soil isolation layer, effectively separating newly laid engineering fill material from the original soil, preventing soil mixing from affecting the site's flatness and stability, while also providing a certain degree of tensile reinforcement and extending the site's service life. Furthermore, laying geotextiles on the surrounding slopes can effectively mitigate rainwater erosion, prevent soil loss, and provide a favorable environment for vegetation growth, achieving a harmonious unity between engineering protection and natural landscape. It is widely adaptable to the renovation needs of various sites such as parks, sports fields, and recreational plazas.
