CDI Innovative Construction Materials evolved out of a family business set up by Ian Larnach in 2002 called Ian Larnach Associates (ILA). Initially ILA ran as a construction consultancy business to help introduce new products into the industry as well as providing sustainability and Code for Sustainable Homes services. Ian initially discovered Lewis Deck on the back of a visit to a trade show, in Birmingham. Within 4 weeks Ian had a contract to import Lewis into the UK.

The Lewis Deck very became the strongest product that ILA dealt with and as a result CDI (Northern) Distribution (a partnership business) was set up in 2009 as the distribution body for the sheets with Chris Holt as MD.

Since 2012 the company has seen year on year growth and it naturally evolved into CDI Innovative Construction Materials Ltd as more and more products were added to our portfolio. As well as Lewis Deck we offer a number of construction solutions from Reppel bv, the manufacturers of the Lewis sheet, as well as having our own construction solutions (see “Our Systems”).

CDI has the exclusive distribution rights for the Reppel suite of systems for the whole of the UK and Ireland

Ian retired from the business in early 2016 due to ill health, and Paul Larnach joined the company as a director to help the business grow further.
