Low Impact Development LID Hydrophilic Rock Wool Soil Amendment

This product offers an efficient in-situ soil improvement solution for LID facilities. In sponge city retrofit projects, many existing green spaces suffer from compacted, low-permeability soil. Excavation and replacement are costly and disruptive. This fibrous amendment mixes with native soil without disturbing existing vegetation, transforming "old green spaces" into "sponge green spaces."

• LID facilities
• Sponge city retrofit projects
• Old residential area greening renovation

• In-situ soil improvement: Eliminates the need for excavation and replacement, avoiding large-scale earthwork costs and disruption. Offers a low-impact, high-efficiency retrofit solution for schools, hospitals, residential areas, and other settings where major construction is impractical.
• No damage to existing vegetation: The heavy metal content is extremely low and non-toxic to plants. Leaves native soil intact, preserving existing root systems. Avoids the risk of large tree mortality from soil replacement.
• Long-term effectiveness: Inorganic wool fibers with stable physicochemical properties do not degrade over time, eliminating the need for periodic reapplication.
