The slopes that are prone to failure and collapse by sliding can be enhanced and made serviceable, safe and secure. For this numerous efficient and reliant methods are used to stabilize the slopes. The methods usually engage one or more of the following measures, which either reduce the mass that are vulnerable to cause the sliding and collapse or successfully helps improving the shear strength of the soil in the failure zone.

  1. Slope flattening reduces the weight of the mass tending to slide/collapse. It can be employed wherever possible.

  2. Proving a berm beneath the toe of the slope enhances the resistance to movement. It is especially useful when there is a possibility of a base line.

  3. Drainage helps in reducing the seepage forces and thus enhances the stability of slopes. The zone of subsurface water is lowered and infiltration of the surface water is prevented.

  4. Densification by the using explosives, vibroflotation or terra probe aids in increasing the shear strength of cohesionless soils and hence increases stability.

  5. Consolidation by surcharging, electro-osmosis or various other reliable effective methods help in enhancing the stability of slopes in cohesive soils.

  6. Grouting and injection of cement concrete mixture along with other compounds into specific zones help in increasing the stability of slopes.

  7. Sheet piles and retaining wall structures can be installed to provide lateral support and to increase the stability.

  8. Stabilization of the soil helps in enhancing the stability of slopes.

  9. Other relative inexpensive methods like for slope flattening and drainage control may be usually applied.
