The facing walls can include all types of mesh or loss bar reinforcement, depending on the design criteria and hydrostatic/earth loadings imposed on the liner wall.
The sprayed concrete process ensures that dense concrete is applied to the underside of the capping beam, which is usually a problematic area when casting concrete walls.
If required, hydrophilic water bar can be incorporated into the structure at the wall/ floor joint and wall capping beam joint. Water proofing admixtures can also be included within the sprayed concrete mix.
There are also a number of finishes available which can lead to cost savings.
1. ‘As sprayed’
2. Screeded (usually used in conjunction with cavity drain)
3. Floated (gives render-like appearance)
