Geotextile

The HBA tiles are each 5 x 5 metres in size. They are closely packed, unlike the sparse LBA. However, they do not touch completely. Between any two tiles there is at least a 10 centimetre gap. In order to stop weeds from growing up in these gaps, long sheets of geotextile weed suppressant are placed along the inner intra-tile boundaries.

No, this is not the world's largest toilet roll! Instead, this is a roll of geotextile material, being placed at the field edge. The trolley to carry it has been custom built for this purpose. The crew are Eric Petrusma (left) and Harry Smith.


Here Harry Smith spools out another length of geotextile. Eric Petrusma is in the distance pulling it forward.
