Hydraulically Applied Blankets

Spraygrass® Hydraulically Applied Blankets provide 100% coverage that protect against heavy rain, wind and bird attack.

They are created with specially formulated mulches mixed with water and seed to form a slurry that is pumped through a Hydromulcher onto the area to be revegetated.

The mixtures of these products form a protective blanket that conforms to soils perfectly, even on irregular ground surfaces. The slurry they can be pumped at high pressure, so it can be sprayed onto the most inaccessible and irregular sites, covering vast areas quickly and cost effectively.

Hydraulically Applied Blankets are usually cross-sprayed in opposite directions for maximum effect however a single application can be used if required.

Once dry (24 hours) the products provide a highly beneficial micro climate for germinating seeds, with excellent water retention properties as well as low rainfall runoff characteristics.

​​These products are non-toxic and can be sprayed directly over existing vegetation, such as areas damaged by bushfire, often without any prior site preparation.

Hydraulically Applied Blankets are less labour intensive can often be applied with less impact to the surrounding vegetation than conventional erosion control matting products

​The mixture can also be modified to suit particular applications, like specific native grass seeds or as a weed control mat.

​For best results Spraygrass recommends a Full Soil Chemistry test to determine if additional ameliorants are required to be added to the Hydromulch mix or applied separately to the subsoil or topsoil.

HydroCompost Matrix™ or Similar Products

There are many occasions where there is a lack of topsoil, or soil which lacks trace elements and organic material. HydroCompost Matrix™ is a Hydromulch application which incorporates everything required for successful revegetation, even in the toughest environments. Moisture retentive wood fibre mulch and associated seed is mixed with a binder, fertilizer and natural, organic compost to create a complete solution that produces excellent results, regardless of the soil condition.

​HydroCompost Matrix™ application provides up to 70% moisture retention while simultaneously improving the transmission of water through the soil providing an medium in which the seed can germinate while and at the same time giving added protection against wind and water erosion before the establishment of grass.

HydroCompost Matrix™ is applied with a thickness of around 5mm to 6mm if applied at 4 – 5 tonne/ha.

Note: Other additives may include Soil Ameliorants such as Gypsum and Lime and growth stimulants such as fish fertilizer.

For best results Spraygrass® recommends a Full Soil Chemistry test to determine if additional ameliorants are required which can be added with the Hydromulch mix or applied separately to the subsoil or topsoil.
