    CONCRETE DNA

    Manufactured with a blend of technology and craftsmanship, FLOAT UHPC is created using a proprietary formula. This includes high-performance cement, pozzolanic materials, mineral-rich fine aggregates and tailored admixtures for enhanced durability.

     

    SILICA FREE

    Our panels are free of harmful crystalline silicon dioxide (< 1 M.-%) offering peace of mind to those who cut or install our panels. This silica-free formulation supports healthier work environments and complies with evolving international standards.

     

    FIREPROOF

    Our precast panels meet the requirements of fire protection “non-combustible“ and is environmentally neutral as no additional treatment or chemical coatings are necessary.

     

    INSULATION INNOVATION

    Our concrete are developed to support energy-efficient design through their inherent insulating properties. With a thermal conductivity (K-value) of 0.118 W/m·K and a thermal resistance (R-value) of 0.110 m²·K/W at 13 mm thickness, they offer a notable improvement over standard concrete. 

     

    WATERPROOF

    FLOAT panels offer dual-layer water protection: a dense surface matrix that reduces porosity, paired with a penetrating polymer-hybrid sealer for complete waterproofing. This system ensures resistance to rain, humidity and environmental moisture.

     

    ACOUSTIC COMFORT

    By absorbing and diffusing sound energy, FLOAT panels reduce reverberation and sound reflection. Their engineered matrix and lightweight design enhance acoustic clarity, supporting more peaceful and focused environments indoors and out.

     

    EASY INSTALLATION

    The lightweight nature of our concrete wall panels allows for easier handling and faster installation. Reduced panel weight also means less load on structural supports, which can contribute to lower construction costs.

    SUSTAINABLE CONCRETE

    Sustainability is built into every FLOAT panel. Our UHPC formulation reduces cement use and cuts embodied CO₂ by up to 32%. Lightweight design improves transport efficiency, while our low-waste, low-energy process supports a circular production model — all without compromising performance or visual impact.
