- About CDI
CDI Innovative Construction Materials Ltd is a family run business specialising in a range of high performance floors.
At CDI, we pride ourselves with providing a personal and professional service to ensure that our floors meet the highest expectations of each client and project, our approach is to ensure any technical or buildability questions are answered quickly and efficiently. Our aim is to push the boundaries of what can be achieved with our systems to solve the interesting situations that our customers find themselves in when searching for a solution to their individual refurbishment or build.
We cover the whole of the UK and Ireland from our office and warehouse in Co. Durham in the North East of England. We can often be found on the road, on the train or in the air, visiting Architects, Engineers, building sites and clients to give CPD style presentations or instructions on how our systems are installed to achieve the desired results. We also spend a lot of time at trade shows showing off our systems and getting to talk and discuss face to face with potential clients on how our systems will benefit differing types of construction projects from small domestic extensions to large multi-storey buildings.
CDI are the sole distributor for all Reppel bv. systems within the UK and Ireland, these include the Lewis Deck, Op-Deck, Lacomet, Hody, Max4 and Lewis FastSlab systems. The Lewis FastSlab foundation system is our own system, tying together a number of elements from a number of manufacturers both here in the UK and over in Holland.
Our small but professional team are always on hand to discuss ways in which we can help you get the most out of what ever project you may be looking to develop. Please feel free to contact us either by phone, email or through the chat function on this website and we will happy to start a conversation.
