Stravifloor Deck

Floating Deck System

Stravifloor Deck* is a low-profile floating floor system using a proprietary dovetailed metal deck for thin concrete pours. The system's high bending stiffness allows for concrete toppings as thin as 2 inches (50 mm), making this system a great solution for projects that require a low-profile or lightweight concrete floating floor. It is also suitable for areas with high live loads. 

This system provides a high-performance floating floor system for excellent structure-borne and airborne noise isolation, while minimizing any impact on the available floor-ceiling height.

  • High Performance

    High Performance

    Using resilient supports outstanding dynamic to static stiffness (Kdyn/Kstat) ratio, allowing a low resonant frequency at minimal deflection.

  • Discrete System

    Discrete System

    Using durable and with exceptionally low creep rate discrete resilient supports.

  • Reduced Build-up Height

    Reduced Build-up Height

    Using a dovetailed metal decking, light gauge galvanized steel reinforcement sheets, the system has high bending stiffness allowing for concrete toppings as thin as 2 inches (50 mm).

  • Lightweight Systems

    Lightweight

    Lighter than massive concrete systems due the deck sheet shape used as formwork, a metal deck, moisture resistant, light and easy to handle and free of autochthonous parasites or other harmful organisms.
