Soil and waste pipe systems provide sound insulation ratings for hydraulic services in a ceiling cavity, bulkhead or a duct. These systems have been designed to comply with BCA requirements for each state.

The soil and waste pipe systems cover a range of situations including bathroom ceilings, bedroom or habitable room ceilings, as well as ducts. Certain systems may require the pipes to be wrapped but alternative systems exist that include covering the pipes in plasterboard or the use of a false ceiling when wrapping is not practical.

This section includes only the system tables for soil and waste pipe acoustic systems. For installation requirements, refer to the relevant wall or ceiling section.
