Triple Shaft

Pre-cast concrete lift shaft

Following the success of the Twin Shaft system, Waycon Precast now offer a Triple Shaft system. The Triple shaft follows the same high quality design principles of the Lift Shaft and Twin Shaft, incorporating three separate lift shaft compartments, reducing both build time on site and space requirements.

All shafts are bespoke products and can be configured to suit any project. Precision engineering means that when it arrives on site the sections are quick and safe to install.

Technical Information


Lift Shafts can be built to suit any size, 25mm increments are preferable to suit our standard moulds but any size is achievable.

Wall Thicknesses:

The Triple Lift Shaft has a standard wall thickness of 140mm. This can be increased dependant on design requirements. Other common wall thicknesses are 150mm, 160mm & 200mm. The shaft will have two 150mm minimum internal walls.

Lift Loading:

Lift Shafts are as standard designed to support all loading from the lift equipment during installation, operation and maintenance. The Lift Shaft can also be designed to support vertical loads from other structural elements such as slabs and beams.

Lift Pits:

Lift Shafts as standard are provided with a pre cast pit section, tanked with a liquid asphalt compound to protect against water ingress.


An engineer designed base to suit local ground condition is required (by others). This may need to cater for residual overturning moments from the shaft in the temporary state.
