We recommend the use of BIOCOVERS® EXTRA (= 200g/m²) for use on difficult and/or steep slopes. When maintenance is required on steep slopes, BIOCOVERS® MINI and MAXI (= 157g/m²) can be damaged during the maintenance activities leading to weaker zones in the fabric. These zones are more vulnerable for weed development. For all standard applications, a 157g/m² is sufficient.
