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.

FAQs

Ask CDI a Question

  • Q

    What are the Lewis Deck sheet sizes?

    A

    Q: What sheet sizes are held in stock for delivery within a few days after order?A: We stock 2500mm and 1300mm sheets.  These are all 630mm wide and 16mm deep.  Deliveries are made via the pallet network directly to site.  The smaller sheets are aimed at small bathroom renovation projects and can be supplied in small numbers via TNT.2.5* and 1.3m sheets allow for the 100mm overlap to occur over a joist, with joist centres being either 300mm, 400mm, 600mm, 800mm*, 1200mm and 2400mm*. (*2.5m sheet only)For larger projects we are able to produce bespoke sheet sizes if required, please get in contact to discuss other options for sheet sizes.

    Q

    Lacomet – How come it has no scrap value?

    A

    Lacomet – How come it has no scrap value?Many of the projects that we get involved in starts with a phone call or email to us from someone researching replacing stolen leadwork. Many of these are old buildings, such as schools or churches, where this isn’t the first time that the lead has been stolen and they call us fed up with having to replace it again full in the knowledge that they will more than likely go through the same problem once more in the near future if they continue to use lead.One of the big benefits that Lacomet FL brings to a project is the fact that it has no scrap value and therefore the chances of it being stolen are massively reduced.Due to the 2 thin aluminium layers, and its five layer total construction, it is of no value to thieves. Lacomet can be recycled but the polyester based coating would need to be de-laminated first and the amount of recovered aluminum is then very low, in fact it would be easier and more profitable to collect empty drinks cans than to mess about stripping Lacomet down. We can also supply stickers that can be placed in strategic locations informing people that what is now on the roof is not lead and that it has no scrap value.

  • Q

    Why don't my Lewis sheets interlock like they do in the video?

    A

    Q: 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.

    Q

    Is this a question?

    A

    If it is, this is an answer.
