This revolutionary product replaces traditional crushed stone with ultra-high-porosity hydrophilic rock wool for permeable pavement base layers. It maintains permeability while significantly increasing water storage capacity and reducing structural dead load, offering a superior base solution for sponge city construction.
| Parameter | Typical Value |
|---|---|
| Density | 100-140 kg/m³ |
| Porosity | ≥ 90% |
| Permeability Coefficient | ≥ 0.6 cm/s |
| Compression Strength | 80-120kPa |
Porosity ≥ 90% provides ample temporary storage for rainwater, offering higher storage capacity without increasing excavation depth. This makes it particularly suitable for urban renewal projects with dense underground utilities and limited excavation space.
Density is only 1/20 that of traditional crushed stone, greatly reducing transportation and installation labor. With permeability coefficient ≥ 0.6 cm/s, it effectively solves the problem of surface ponding.
Achieves the same storage capacity with only 1/3 the thickness of crushed stone. Especially suitable for projects with height restrictions, such as underground garage roof greening or existing building renovations, saving excavation and backfill costs.
Uniform dimensions allow fast placement without heavy compaction equipment. Significantly shortens construction schedules, reduces noise and vibration, and suits projects in urban areas with sensitive construction conditions.
