Hydromulching is a process where a mixture of seed, fertilisers, mulch, binder and water are sprayed on to the site to be revegetated.
Revegetation Contractors recommends Hydromulching for sites with limited access for machinery. It is particularly suited to revegetating steep banks such as road batters and the awkward slopes of creeks and drains. The special binders added to the slurry ensure the mixture adheres to the slope.
Before applying the Hydromulch, Revegetation Contractors recommends that a soil test be conducted. A rough planting surface improves water infiltration, and this may be achieved by scarifying the surface with a comb blade on the grader.
On sites where growth is required immediately it is recommended that the slope be watered to achieve a saturated profile before hydromulching. Additional watering regimes will be designed to meet evaporation and transpiration levels.
If maintenance work such as irrigation is necessary, it should be set up prior to the mulch being sprayed. The irrigation should be designed to apply the water evenly without eroding the mulch. Applying maintenance fertiliser to the site after six weeks will provide the best results.
Hydromulching ensures the soil surface is offered immediate protection whilst providing an ideal environment for vegetation growth. Hydromulching can be applied to sites up to 300 metres away from vehicle access.
