CDI Innovative Construction Materials Ltd (CDI).
Here at CDI Innovative Construction Materials we provide a range of innovative domestic and commercial concrete floors. These are high performance structural floor systems that can be laid on timber or steel joists, providing floor reinforcement, wet room systems, underfloor heating, insulated concrete roof & ground floor systems for high load bearing situations. These are suitable for all types of construction from residential to industrial from new built to renovations.
If you are planning a project that requires a new floor and you are wanting more than the average timber deck that over time will become noisy, move and eventually degrade then please get in touch. Let us talk you through what our systems are all about and how they will improve the feel, strength, performance, and heating efficiency of your floor.
As a small family business we are focused on ensuring that we provide you with the best possible service. So please browse through our website then get in touch with us and discuss your requirements and needs. If you have drawings please send them through, we are happy to do “takes offs” from them to calculate the materials needed and then send you fully itemised quotations.
We are often exhibiting around the UK at various times of the year at trade shows so please have a look at our “Events and Exhibitions” page to see if we will be local to you in the near future.

From the minute we initially contacted CDI, regarding the project that we were planning, they were happy to talk to help us and identify where their systems would benefit what we wanted to build. Even though it took us over a year to go from design stage to the build phase they were always available to get advice from to ensure we got the best floor we could.
CDI's systems are suited to all types of construction methods from fast-track, lightweight offsite building methods including timber frame, light gauge steel frame, structurally insulated panel (SIP) systems, insulated concrete formwork (ICF) to all traditional methods of construction such as brick/ block as well as steel frame and other build methods.
