Vetiver erosion control

Slope Stabilization Calculator

Measure your slope, see how many vetiver slips it needs and compare the cost with a traditional retaining wall. The drawing updates as you type.

Your slope

Change any value and everything updates.

Slope dimensions
m

Sideways, along the contour.

m

Measured up the slope surface.

m

Switching the unit converts your current slope.

Vetiver planting
cm

10–15 cm forms a tight hedge.

€
m

Typical rows are 0.5–1.5 m apart.

Mulch
m³/t

Cubic metres filled by one ton of harvested biomass. Depends on chopping and dryness.

Retaining wall (comparison)
€/m²

Local quotes are often 250–400.

years

Usually 25–100 years.

Vetiver and walls do different jobs, so compare cost with care. A hedge controls surface erosion and shallow slips; a wall holds a structural load.

Structural retaining walls typically last 25–100 years under ideal conditions.

Before you build: vetiver mainly stops surface erosion and shallow slips. On steep slopes, or where a failure could reach people, a building or a road, get a geotechnical assessment first.

These are planning estimates. Real yields and costs depend on variety, climate, soil and local prices.
