Application
This unit describes the skills and knowledge required to install (‘lay-up’) rubber sheeting for the internal lining of tanks, or external lagging on mechanised rollers, carried out in a workshop or off-site facility.
This unit applies to an individual working alone or as part of a team.
The unit principally refers to the preparation of the surface to be lined or lagged, and the successful application of rubber to the surface using adhesive bonding.
No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
