Leaving you with a perfect beautiful strong floating concrete staircase – perfect and precise in every manner.

Cost-effective solution for immediate pouring of concrete staircases of any design.

Get your on-site electrician to insert his light fittings into our staircase cage before concrete pouring and you have a stunning illuminated staircase Our steel cage Formwork is built to individual requirements, especially useful for staircases of intricate designs, and where pre-cast is not an option. The staircase cage formwork is made from steel square tubing with meshing made to the exact shape of your required staircase, once installed is then ready for rebar & concrete insertion – no additional shuttering needed. The stone in your 25mpa concrete blocks the holes in the meshing, allowing a slight stipple of concrete through, making for a perfect surface for plastering. The formwork remains as part of the structure and indeed makes your staircase stronger/free standing so you can then utilize the space underneath the staircase.

We also have a division that can carry out the final plastering of your staircase. We are available at a moments notice for an on-site meeting to measure up and to discuss your staircase. Please see the workmanship on this website and the staircases cage work designs.
