CDI

CDI Innovative Construction Materials provide a wide range of high-performance concrete floor systems for both domestic and commercial projects. Designed for versatility and durability, our solutions can be installed on timber or steel joists, offering reinforced structural floors, wet room systems, underfloor heating integration, and insulated concrete floor and roof systems for high load-bearing applications. They are suitable for all types of construction, from residential to industrial, and for both new builds and renovations.

Our flagship system, Lewis Deck, is ideal for joisted floor applications where acoustics and fire protection are critical. It works seamlessly with screeded underfloor heating and cooling systems, improving efficiency and performance while providing robust structural support.

The Lewis system is highly adaptable, making it suitable for renovations, conversions, and new build projects across a variety of construction types — including traditional, timber, and steel frame, as well as innovative methods such as insulated concrete formwork (ICF), modular off-site construction, and mezzanine floors.

By combining structural integrity, fire and acoustic performance, and compatibility with modern heating systems, CDI floor systems deliver practical, reliable, and efficient solutions for architects, builders, and self-builders alike. Whether upgrading an existing building or designing a new project, CDI provides the expertise and materials to ensure floors meet the highest standards of performance and durability.
