Surface and color options with ultra high performance concrete

Design opportunities with ultra high performance concrete

Hi-Con's own material of ultra high performance concrete (UHPC), CRC i2, opens up a world of design and surface possibilities that challenge conventional choices and inspire experimentation. With UHPC, you can create eye-catching, innovative, and functional buildings, as the material's shapeability and attention to detail allow you to craft a wide range of surface textures and color shades.


The shapeability, lightweight nature, and strength of UHPC also make it ideal for renovation projects where achieving a consistent look with existing structures is essential. This can be achieved in a thinner, lighter, and more durable way, enhancing both aesthetics and functionality.

A unique and organic material

CRC i2 is a unique material based on cement, and like traditional concrete and other natural materials, variations in color and texture are to be expected – and evolving over time. This contributes to the visual appeal of concrete, creating a dynamic and diverse appearance.


Similar to other cement-based materials, CRC i2 is heterogeneous and porous, though with less variation and very low porosity due to its special composition. However, slight variations in color and texture, including possible efflorescence and nuanced differences, may occur during the production of CRC i2 elements.

Creating unique surfaces with UHPC

With UHPC, you gain exceptional opportunities to create surfaces with the exact aesthetics and functionality you desire. We typically use rubber molds to craft various patterns and structures on concrete elements, but we can also use other methods and materials such as wood to add a raw, natural, and organic aesthetic to your buildings.


We offer 9 standard surfaces, but only your creativity sets the limits. Thousands of unique surfaces can be created to suit your project and give your buildings character. We can also incorporate reliefs and unique imprints and patterns in the concrete, truly adding life and depth to your design.


In addition to aesthetics, surface treatment can also prioritize safety. For instance, we can add anti-slip coatings to balconies and stairs to ensure security and comfort.

Color options with UHPC

While UHPC typically has a natural gray color, the concrete can be customized with various pigments to achieve the desired hue. At Hi-Con, we primarily use a light gray or gray concrete base. If you prefer a natural color, a gray concrete base works well, but for more vibrant colors, a light concrete base is the optimal choice. Colored concrete offers greater design flexibility and the ability to create harmony and coherence with surrounding structures and environments. The result is visually impressive buildings that leave a lasting impact.


When it comes to coloring concrete, there are some important factors to consider. Firstly, efflorescence is more noticeable on dark surfaces than on light ones. Earthy tones should be chosen over bright colors, as they are easier to achieve. Additionally, shade variations may occur due to material properties and the production process.


It's also essential to note that colored concrete may fade over time due to weathering. If you desire a specific and consistent color tone on the concrete, opting for a painted surface is recommended. However, it should be noted that a painted surface will affect the texture of the concrete surface and require ongoing maintenance.

Incorporating brick and other materials

In addition to creating various textures and colors on concrete elements, UHPC also offers the opportunity to incorporate other materials such as brick, monolith, tiles, and the like to add an architectural dimension to facades or seamlessly integrate balconies with the rest of the building. This combination of materials creates a visually intriguing and textured expression that adds depth and character to the structure. Incorporating brick or similar elements typically occurs after the casting of the concrete elements, offering a flexible approach to the design process.


A prime example of this application can be seen in at the Musical Neighborhood in Aalborg, Denmark, where brick was used to create a modern, eye-catching, and stylish facade. This design choice added a unique identity to the building and established a harmonious connection with the surrounding structures.
