Applications
Moss & Weed Control
When Moss and Weeds become established on hard surfaces, such as block paving; tarmac; or concrete - they are difficult to remove with a sweeper. For this application we have made the Weedbrush. Kersten weedbrushes have been designed to quickly remove weeds and moss.

Artificial Surface Maintenance
In addition to the normal problems we face maintaining hard surfaces; artificial surfaces have infill, which gets compacted and also migrates around the surface. This infill can be de-compacted with a sweeper allowing the surface to drain properly. The sweeper will also even out the distribution of infill and stand up the grass, making the surface much nicer to use.

Winter Maintenance
Keeping pavements and highstreets open is also a challenge, often undertaken by council teams. A Kersten Plough or Spreader can allow facilities, key bus stops and other transport networks to remain accessible to pedestrians.
