Remedial measures for slope failure

Remedial measures to prevent or stop slope failure:

1. Flatten the slope or reduce its height; provide berms or benches.
2. Unload the top by removing soil or load from the crest, and place a berm or counterweight at the toe.
3. Drainage: surface drains and catch-water drains, sub-surface and horizontal drains, and sand blankets to lower the water table and pore pressure.
4. Retaining structures: retaining walls, gabions, sheet piles or piles at the toe.
5. Reinforcement: geotextiles, geogrids, soil nailing, rock bolts and anchors.
6. Vegetation and bio-engineering to bind the soil and stop erosion.
7. Soil improvement: compaction, replacement of weak soil, grouting, or lime and cement stabilisation.
8. Control of vibrations and erosion at the toe, with proper protection such as riprap.
