Types of Cast Floors

Epoxy floors

Very durable and resistant to chemicals.
Ideal for industrial applications.

Polyurethane floors

More flexible and water resistant than epoxy.
Suitable for residential and commercial spaces.

Cement-bound cast floors

Made of cement and resin.
Gives a natural, concrete-like finish

Acrylic cast floors

Quick-drying and suitable for outdoor areas.

Epoxy floors

Technical specifications:

Density: 1.2 to 1.5 g/cm³
Tensile strength: 30-40 MPa
Elastic modulus: 2-4 GPa
Thermal conductivity: 0.2 W/m K

Composition of Materials

Resin: Epoxy resin is the primary binder.
Hardener: Usually a polyamine.
Fillers: Sand, quartz, or other minerals for extra strength.
Pigments:* For color and aesthetics.

Applications

Industrial floors
Garages
Laboratories

Advantages and disadvantages

Advantages: High mechanical strength, chemical resistance.
Disadvantages: Less flexible, sensitive to UV discoloration.

Sustainability And Environmental Impact

Longevity: Long-term use reduces the need for frequent replacement.
Materials: some cast floors can be made from recycled or sustainable materials.
Maintenance: lower cleaning costs and less use of cleaning products.

Underfloor heating and floor cooling

Underfloor heating: Very suitable because of its good heat conduction.
Underfloor cooling: Generally also suitable, but it is important to discuss this with the manufacturer.

Future developments

Sustainability: There is a growing demand for environmentally friendly options.
Technology: Innovations such as integrated LED lighting or heating elements are in development.

Conclusion

Cast floors offer a range of options suitable for various applications, from residential and commercial spaces to industrial environments. Although they may require a significant initial investment, they offer advantages in terms of durability, maintenance and aesthetics. Compatibility with underfloor heating and cooling makes them an even more attractive option. With continuous innovations and a growing focus on sustainability, cast floors are a future-proof choice for any space.
