Beddings are primarily made up of granular or concrete materials. They are primarily used for the following purposes:

☛ They are used to provide a more uniform support for the under pipes so that the bending moment longitudinally can be reduced greatly.

☛ In order to enable the pipes to get more load-supporting strength.

☛ They are also used to act as a platform to achieve a more correct alignment and level pre and post construction.

☛ In case of pipes which contain spigot and socket joints, it enables pipes to get supported along pipe lengths in place of sockets. Otherwise it can lead to uneven stress being induced on the pipes eventually damaging it.
