- About CDI
A balcony is an exciting and often focal point to any house, apartment or other building, giving that feature a solid concrete feel to the surface conveys the quality of this key element of the building to all that use it.
Depending upon the span to be achieved we have a number of systems that can be effectively used to create balconies for houses or commercial buildings including apartments or hotels, etc. These will then have a concrete finish that can be used as is, with an appropriate concrete water-proofing system, or with a tiled or other finish.
The drainage falls can be built into the concrete and a suitable channel, square or round drain can be installed within the concrete layer to complete the installation.
If cantilevers are to be achieved, these can also be accommodated with a number of our solutions.
Our systems can be used to provide a thin and relatively lightweight concrete balcony deck which can then be waterproofed and tiled. Suitable tiles, if this is the finishing route to be taken, can include ceramic, stone, porcelain, etc.
We are happy to provide advice and guidance for these types of installations and have seen a number of solutions used for the frame to support the deck.

Deliveries are made via the pallet network directly to site.

Q
Why don't my Lewis sheets interlock like they do in the video?
AQ: Why don't my sheets interlock like they do in the video? A: The sheets have two sides (one printed, one plain), the dovetails on either side are different widths, it is then necessary to alternate the sheets print up and then print down.
