CDI Innovative Construction Materials

CDI Innovative Construction Materials (CDI-ICM) provide a range of innovative domestic and commercial concrete floor systems. These are high-performance structural floor systems that can be laid on timber or steel joists, and can provide floor reinforcement as well as insulated concrete roofs and ground floors for high load-bearing situations. The systems are also ideal for creating wetrooms and for installing underfloor heating.

CDI-ICM's systems are suitable for all types of construction from residential to industrial, new builds to renovation projects.

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 CDI Innovative Construction Materials can help. 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.

Lewis Deck

Lewis Deck, as part of a joisted floor system, provides a first-class solution where acoustics and fire protection are key concerns. The Lewis Deck system also works very well with screeded underfloor heating and cooling systems, allowing them to work more efficiently than without the sheets in place.

Lewis Deck provides a number of solutions for renovations and conversions as well as new build projects, and can be paired with all types of build systems including traditional, timber or steel frame as well as newer methods of construction such as ICF (insulated concrete formwork) and modular off-site construction. Lewis Deck can also be used with mezzanine floors.

In addition to standard domestic separating floors, Lewis Deck provides exceptional solutions for bespoke acoustic floors within live music venues, night clubs, restaurants, recording studios, recreational performance studios, specialist test labs, plant rooms and many other commercial applications.

Lewis Deck provides the following:

• High-performance acoustic floors
• Underfloor heating in suspended floors (only 52mm thick)
• Floors on any type of beam or joist
• High load-bearing capacity
• Low dead loads
• Thin overall thicknesses (generally 50mm, but ranging from 36mm to 75mm)
• Simple and easy installation
• Fire ratings up to 120 minutes
• Compatible with new builds, renovations and conversions
• Suitable for liquid screeds and fine grade concrete
• Suitable for use with ceramic or stone tiles
• Great for wetrooms
• Span joists (up to 2.5m centre to centre) or can be laid directly on existing floors

CAD drawings and BIM models are also available.

The production facility is ISO9001 certificated and the Lewis Deck system is fully tested and carries a number of certifications — find out more on support section of our website.

The HODY steel-concrete composite floor

A HODY® steel-concrete composite floor consists of a unique trapezium profiled steel sheet, which functions as permanent formwork and reinforcement, additional reinforcement (as detailed in the following illustration) and a minimum layer of C20/25 quality concrete.

The result is an extremely strong, fire-resistant, sound insulating, relatively thin, lightweight composite concrete floor that provides a simple to install and cost-effective solution.

During the curing period, HODY® sheets constitute the formwork supporting the weight of the concrete and allow the transfer of weight from the assembly load to the supporting structure. After the curing period, the HODY® sheets, usually with an additional layer of mesh reinforcement within the concrete, produce an integral, robust composite floor.

HODY® can be used with the following flooring systems:

• HODY® on steel beams
• HODY® between steel beams
• Unsupported span
• Sound-insulating floor structure
• IFD floor structure
• Wood-concrete composite floors
• Permanently visible constructions (HODY® can be provided at the bottom with a polyester or PVDF coating in RAL colour. Colour options depend on availability).
