In agriculture, alternatives to traditional waterproofing materials include natural substances like clay, which can be used to create barriers against water infiltration, and organic materials such as straw or compost that can help retain soil moisture. Additionally, hydrophilic polymers can absorb and retain water, reducing the need for waterproofing. Permeable fabrics and geotextiles can also be used to control water flow and prevent soil erosion. These alternatives can be more sustainable and environmentally friendly compared to synthetic waterproofing materials.
