The award-winning House Bozwana demonstrates the innovative use of decorative concrete.
The decorative use of concrete finishes in the construction of House Bozwana, overall winner of the Lafarge Artevia Decorative Concrete Awards last year, showcases the innovative possibilities of decorative concrete as building material.
The awards were introduced in 2009 to show how decorative concrete can create better, more durable structures and enhance the environment in which they are located.
For years, Chryso SA has supplied a variety of products that form part of the mix for Lafarge’s acclaimed Artevia range. Specifically for the construction of House Bozwana, Chryso supplied a specially formulated Lanxess Bayferrox Sandstone pigment to colour the concrete in selected areas as well as products such as CHRYSO®Fluid Optima 100, CHRYSO®Fibre Plus, CHRYSO®Deco Lav PO5 and CHRYSO®Deco Mat.
Admixture CHRYSO®Fluid Optima 100 is a new generation super-plasticiser which substantially extends concrete workability and is compatible with most types of cement, while CHRYSO®Fibre Plus is a high-performance product that controls cracks and prevents bleeding, while also enhancing the fire rating of concrete.
Safe and environmentally-friendly, CHRYSO®Deco Lav PO5 economically improves the definition of exterior forms as well as the technical quality and durability of structures. It can be used with different types of aggregates from different regions. CHRYSO®Deco Mat is an acclaimed surface protector for concrete and mortar.
The judges found that House Bozwana was exceptional as it showcased various finishes of decorative concrete:
• Polished finishes to create a stylish impact for the entrance, stairs and entertainment areas.
• Exposed finishes to provide low maintenance and gravel-texture appearance in the driveway.
• On the stairs and entrance areas, the beautiful Artevia finishes were set off to a stunning effect through the use of natural, off-shutter Lafarge Agilia, combined with steel.
Responsible for the award-winning design, Nico van der Meulen Architects worked on the project with the installers and polishers, Ocean Side Trading.
Commenting on the merits of decorative concrete in the design field, architect Nico van der Meulen says the concept has great potential in South Africa, but it calls for skilled and experienced applicators capable of achieving the desired standard.
“The standard of the applicators’ workmanship and skills ultimately determine the quality of the finished product,” he states.
