Mass concrete nominal linings may need to be designed to be pressure relieved to prevent the
build-up of water pressure loading; to this end, weep holes and or drainage garlands are incorporated.
The minimum thickness is governed by practical considerations during casting, specifically related to the stiffness of the kerb ring during handling and placing of the concrete; 300 - 450mm thick nominal concrete linings are typical.
Benefits:
Minimises concrete usage, whilst providing a fully serviced shaft environment.
Addition of steel fibres can increase strength.
