SF#09 Hydroseeding for Post-Mining Site Rehabilitation

Hydroseeding, also referred to as hydromulching, is a grass planting process. It is a fast, cost effective and high-quality method for seeding vegetation, land rehabilitation and erosion control. The process is fast, efficient, and economical and is usually more effective than conventional seeding and more economical than conventional sodding.

The process begins by mixing mulch, seed, tackifier, germination and growth promoting agents, fertilizer, and water in a Hydroseeder to form a slurry.  Mulch is any material that is spread or laid over the surface of the soil as a covering. It is used to retain moisture in the soil, suppress weeds, keep the soil cool, and make the garden bed look more attractive. The most common types of mulch include: compost, grass clippings, shredded leaves and straw.

The slurry is applied to the topsoil surface of the area to be rehabilitated with a high-volume pressure hose or tower. Once applied, the slurry mixture enhances initial growth by providing a microenvironment beneficial to seed germination and turf development, which will also provide a uniform cover for dust and erosion control. 

The method is ideal for a variety of seeding requirements, including lawn seeding, erosion control, slope stabilization, and large-scale area rehabilitation post mining activity.
