land rehabilitation Tubes

Business and government infra-structure developments place huge demands on mother earth in the form of new and improved road networks and land excavations in the mining and industrial sectors.

Despite all the good intentions and efforts companies and government put into rehabilitation of land during and after construction work is undertaken, many rehabilitation systems and practices are not sustainable. Inclement weather often results in work having to be re-done because of water and wind erosion.

Grassnet is a novel solution to land rehabilitation. Grassnet is a knitted mesh net incorporating horizontal tubes which accommodate sand, compost and seeds. It is sold in 1,5m x 50m roll lengths. The horizontal tubes are filled with the correct growing medium by means of an electrically driven auger filling machine.

During the filling process, Grassnet is simultaneously lowered down the working incline or slope and positioned in place. The Grassnet is anchored in place to stabilise the net and ground surface below the net.
