The Retro Shaft allows Waycon’s pre-cast concrete lift shafts to be installed alongside or inside existing buildings.

Where access is difficult and disruption must be kept to a minimum, this approach allows lift shafts to be rapidly assembled in difficult locations with minimum disruption.

The Retro Shaft adopts the same high quality design principles as the standard Lift Shaft system, but incorporates a tie provision between the shaft and the existing structure and can also include precast walkway slabs and wing walls to bridge the gap between the two structures.

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 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.

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.
