Nyasha Gardens has effectively utilised Helicopters as an application method on projects where truck access was limited. HydroTrucks continuously agitate the mix which is then pumped into the aircraft’s tank ready for application to ensure the product is evenly distributed.
Helicopter application of hydromulch or dust suppression is efficient in covering large areas, including remote sites with steep or rugged terrain, in the least amount of time. Helicopter application is extremely suited to tailing storage facilities (TSF) and ash dams where vehicle access is limited, and safety concerns arise.
HYDROSEEDING
Hydroseeding is the hydraulic application of water, seed, fertilizer and the option of growth-supporting additives utilizing purpose-built hydroseeder trucks to provide environmentally friendly and safe revegetation of large areas.
Hydroseeding is the hydraulic application of a mixture of seed, water, fertiliser and tracking dye sprayed on the topsoil. It’s designed to provide fast, economical and efficient revegetation.

REVEGETATION
The deterioration of soil by water, wind and other natural forces can be a major ecological problem if not handled correctly.
Here at Nyasha, we believe that revegetation is the best form of erosion control. Damaged and depleted soils require much more than the conventional hydroseeding treatments to achieve healthy and sustainable long-term growth.
“Nyasha Gardens uses innovative techniques grounded in science to deliver effective, environmentally friendly revegetation, dust suppression and erosion control solutions for South Africa’s mining, oil & gas, civil and infrastructure projects.”
How IT Works
Damaged and depleted soils require much more than the conventional hydroseeding treatments to achieve healthy and sustainable long-term growth. Successfully revegetating damaged landscapes following construction or mining activities can be partially difficult in the harsh South African environment. Diverse soils, site and weather conditions across the country mean that there isn’t a ‘one size fits all’ revegetation solution for every revegetation and erosion control project.
Vegetation influences slope stability in two ways: through hydrological effects and mechanical effects. The roots of plants physically reinforce soils, resist erosion and increase the infiltration of water into the soil by forming physical pathways. Plants have extensive root systems that secure the layers of soil together in an interlocking grid, reducing displacement and stabilising embankments and batters. There are two common techniques that are effective for revegetation; Hydroseeding and Hydromulching. Both have been proven effective in revegetating and stabilising soils.
