 At SGI we take pride in our work and enjoy seeing your project develop to the best possible product as much as you do. To help on this endevour we provide maintenance and establishment services, to fit in with your project requirements. From fertilising, to keep the grass healthy and vibrant, to mowing and establishment of lawn areas or batter protection works.

Soil Supply & Levelling

To create a good finished lawn, your grassing project should have a good start. It is important to provide a good topsoil base for the grass seed to get its roots into. To avoid pooling and providing runoff of extra water it is essential to get the levels right from the start. At SGI we strive to use top quality soil and provide the topsoiling job your project deserves.

Native Revegetation

From mine sites, to landscaped garden beds, to revegation of disturbed areas, seeding of native species is a huge portion of environmental erosion control. With the progress of mining, civil projects and housing estates, it is often unavoidable to prevent the damage of native trees and plants. With the ability to source native seed SGI can provide the native revegetation requirements of your project.

What Is Spray Grass ?

Spray Grass or Hydromulch is the combination of grass seed, fertiliser, binder (Glue), coloured dye and a mulch product. This mulch can consist of either wood fibre, paper or straw and can be alternated to suit the particular job requirements.

All products are combined in a specially designed tank and sprayed onto the ground as a paper mache type application. The hydromulch provides the seed with protection from the elements and provides extra water holding capabilities for the seed. With adequate watering and care, germination can be achieved in just a matter of days.

Spray Grass Industries uses predominantly recylcled materials for their hydromulch solutions.

Refined Erosion & Dust Control

Here at Spray Grass Industries, we know the severe weather experienced in the Top End. Without proper protection from these severe weather conditions, the damage caused by erosion can be devestating, often leading to enviromental damage and huge restoration costs. Our experienced team has the products and knowledge to combat erosion & dust effectively. From the application of Jute mesh and silt fencing to the finest dust suppresssion and erosion control products.

Native Revegetation

Whether its the rehabilitaton of mine sites, landscaped graden beds or revegation of disturbed areas, seeding of native species is a huge portion of environmental erosion control. In the Top End we have a large proportion of  native bushland. With the progress of mining and development it is inevitable that some of these areas may need to be cleared for works to be completed. With the use of seeds from native grasses, trees and shrubs, SGI can cater a revegetation solution for your project.

Soil Supply & Spreading

Creating a good finished product begins from the start. The most important part of a good lawn is the topsoil that is used. It is important to make sure that the soil is free from weed, to ensure that your not battling weeds from the very beginning of your grassing project. At SGI we pride ourselves in the quality of our workmanship and ensure that all soil levelling is completed to the best possible product. With the machinery and knowledge to tackle both small and big projects, the team from Spray Grass Industries are happy to talk to you about your topsoiling needs.
