Revegetation & Erosion Control (Spray Seeding)
AquaSeeding has a proven track record in using fast, cost-effective, environmentally responsible, spray-on Revegetation and Erosion Control processes such as:|
in which high pressure pumps and/or blowers homogeneously and accurately apply various water, seed and additive-based mixtures and mulches across a variety of terrains for an extensive range of projects.
Check out the above links for frequently used terminology to help you better appreciate the scope and advantages of this type of work. In particular, it is worth taking time at the outset to gain an understanding of the difference between HydroSeeding and HydroMulching.
The above techniques, also referred to as hydraulic seeding, spray-seeding, spray-grassing, jet seeding, aqua-seeding, etc, which have been proven across Australia and around the world, are excellent for revegetation and erosion control of large areas or sites that are difficult to prepare or access (eg steep or irregular slopes, bushfire-damaged areas, etc).
Spray seeding technologies / techniques are suitable for a variety of applications from simple residential lawns to the most demanding infrastructure projects using complex slurries of seed blends, fertilisers, binding agents, dyes, organic fibres (paper, wood, etc), and other specialist agents (eg soil conditioners as required). The slurry can be pumped from a truck-mounted "cannon" or through a hose of up to 200m length - so apparently inaccessible areas can be readily reached.
A wide range of effects and results can be achieved by varying the composition of the slurry. For example, where erosion control is a priority, a Bonded Fibre Matrix (BFM), using a wood-fibre mulch product such as Enviroguard is ideal because it stabilises the surface immediately and holds it in place for several months whilst the seeds, which are contained close to the ground in the matrix, have time to germinate.
Spray seeding is particularly appropriate for varied terrains because the mulch or BFM follows the contours of the surface perfectly, ensuring 100% coverage. Quite different approaches may need to be taken to ecologically sensitive areas such as forests or water catchment regions, alpine and coastal areas, for example.
Weather, site orientation, season, rainfall, run-off characteristics, public and staff access, as well as botanical and even aesthetic considerations, are just some of the factors that need to be taken into account in many projects.
Hydraulic seeding is ideal for large areas as well as applications where:
- Access is difficult and even unsafe
- Site preparation is not physically or economically viable
(eg stabilising steep slopes against erosion after bushfires)
- The surface is uneven and irregular.
AquaSeeding can advise on the correct grasses and other additives for each application.
