Roof Planting Box
▪ High Integration
▪ Physical Reuse
▪ High Pressure Resistance & Long Liespan
▪ Dual-Layer Root Barrier Protection
▪ Optimized Thermal Insulation
▪ Roof Protection
A modular rainwater storage and drainage planting container designed for rapid water infiltration, featuring a double-layer root barrier, easy installation, and optimal plant growth conditions. This lightweight, aging-resistant, and eco-friendly solution integrates thermal insulation with ecological benefits, combining functions of "infiltration, retention, storage, purification, utilization, and drainage" to align with Sponge City principles.
Integrates traditional protective technologies including "protective layer, root barrier layer, durable water pump, isolation layer, and filtration layer" into a unified system. Offers comprehensive protection without requiring multilayered subcontracting.
Enhances water retention efficiency: initial drainage prevents bidirectional water absorption, while self-sustaining plant root capillary action enableswater reuse.
Obust baffle structure: Engineered for superior compressive strength to meet demanding pressure requirements. Lifespan: Exceeds 20 years under standard conditions.
Combines membrane and structural barriers to create a "double defense" against root penetration, eliminating risks of corrosion, leaks, or water damage.
The coated design and internal water storage cavity absorb over 90% of heat, significantly improving indoor cooling efficiency.
Elevated planting structure: Prevents direct contact with the roof surface, minimizing wear. Enhanced durability: Prolongs roof lifespan while maintaining functional integrity.
