The application of a seed, fertilizer, wood fibre, and binder slurry using a specially built Hydroseeding Unit. This unit incorporates the seed, fertilizer, wood fibre, and binder in a slurry mixture with water, and then sprays this slurry (or Hydramulch) on the area to be treated via a high pressure pump system.

Hydramulching is the most commonly used method of revegetation of disturbed areas on civil construction sites. Wood-fibre is used in this application to provide a bulking agent for the slurry, as well as to provide a thin layer of mulch to help retain moisture, increase the organic carbon in the soil and also to help promote seed germination. The binder causes the individual fibres of wood to adhere together and form a mat. It also binds the fibre and seed to the soil, aiding in minimising erosion.

Hydramulch can be applied to areas ranging from flat surfaces, up to banks 1V:1H steep. The amount of wood-fibre in the slurry can also be varied to provide varying amounts of coverage and erosion protection requirements.

Expected Growth
Growth is generally faster than for Seed Drill or Hydroseeding, but again is dependent upon local rainfall.

Relative Cost
Hydramulching  is more expensive than hydroseeding, due to the inclusion of the protective medium; the wood-fibre and binder.
