Efficient drainage This flexible drainage pipe promotes water absorption and infiltration, quickly channeling excess water during heavy rainfall, making it an indispensable drainage solution for horticultural landscaping projects. Material and filtration The outer layer is made of a nonwoven filter layer and polyester fiber, ensuring effective filtration and preventing sediment from entering the pipe. Extendable length and compatibility You can directly connect two permeable pipes to increase the length, or you can use PVC pipes to connect (PVC pipes are not included). Multi function performance The pipe combines water absorption, water permeability and drainage. It allows rainwater to penetrate into the surrounding soil and store it. In seasons with low rainfall, it can store rainwater in the soil. Use scenarios Garden bed and planter drainage: prevents surface water buildup while promoting soil infiltration and moisture storage for plants. Sloped landscape or courtyard areas: directs excess runoff away from foundations and reduces erosion while filtering sediment. Irrigation support and soil moisture retention: when rainfall is scarce, stored rainwater helps sustain soil moisture for nearby greenery. Notes PVC pipes are not included. This product is designed to connect with permeable pipes or PVC piping as part of a flexible drainage system.
