#$%^&*AU2018100868A420180920.pdf#####6 ABSTRACT The vegetation ring is a flange surrounding the edge of an access cover. The vegetation ring is one homogenuos structure with the frame. It is cast into the frame structure from any material applicable for useage as outlined in AS 3996. It's function is to stop tree/plant root intrusion into the opening of the structure. It eliminates the need for a separate concrete vegetation ring structure. This design and method of manufacture of the vegetation ring is a unique interpretation of the standard which is also eligible for approval.4 Vegetation Ring Figure 1 - Isometric View A Figure 2 - Top View
