Residential Landslide Remediation (Slope Anti‑slide Rehabilitation with high tensile cellular confinement systems)

Residential Landslide Remediation (Slope Anti‑slide Rehabilitation with high tensile cellular confinement systems)

Project Background: A shallow‑seated landslide occurred on the 30° rear slope of residential properties after a hurricane. Continuous soil sliding posed threats to the residential area. The site was constrained with limited access for heavy‑duty construction equipment.

Selected Solution: High‑tensile geocell panels (150 mm height), with 6 fastening tendons per panel, and geotechnical anchors installed at the slope crest. Filled with planting soil for vegetation restoration, supplemented by drainage system and toe‑crushed‑rock backfill.

Construction: Excavation of landslide mass → timber‑fence toe restraint + drainage installation → deployment and anchoring of high‑strength CCS → topsoil backfilling and grass planting.

Performance Outcome: Further soil loss was arrested. Slope stabilization and ecological revegetation were achieved. The solution adapts to confined construction sites and enables rapid disaster rehabilitation.
