Ultra high performance concrete

Slender and bespoke balconies

A world with UHPC balconies

Balconies are in high demand when looking for an apartment. If you are interested in building an attractive residential property or renovating an already existing property, balconies are a factor that is hard not to come around to. 

Our ultra-high-performance concrete balconies are either bespoke or concept elements that can be cast in very large formats and with a free shape-ability that is securely and efficiently mounted on the facade. Besides the obvious functional value of the balconies, they also play an essential role in creating the expression and character of the building. Our UHPC material possesses several significant qualities that provide the architect with the freedom to design and shape the balconies in accordance with their dream and vision for a specific project. Freedom, which is only possible due to the material's extreme strength and durability. With this type of UHPC CRC i2 solution, you get a customized balcony that accommodates your project, and we always make sure to take the requirements of the construction into account. 

Annually, we do more than 100 balcony consultancy projects and we have tried almost all possible mounting principles; balconies suspended by pillars, brackets, parapets or struts, cantilevered balconies without visible bearings etc. There is no challenge too big for Hi-Con, and we are ready to help you reach the finish line of your construction project. 

Types of balconies

We make different types of balconies

The architectural dream of slender, minimalistic and cantilevered balconies are achievable with CRC i2®. Through out the years, Hi-Con has supplied both new builds and renovation projects with thousands of balcony slabs in CRC i2®. 

The minimalistic and extremely slender balcony slab can be cast with a thickness of only 50 mm and weighs around 50% less than a comparable balcony in conventional concrete. Often buildings are able to carry very large balconies of this type, which increases the value of the apartments and the applicability for the residents.

The design options are many with balconies with one or more parapets. The parapets can be designed in verious heights and furthermore function as a privacy screen. 

You can design the parapets as a part of the load bearing structure, which makes it possible to use hidden connections and a solution with parapet balconies is a great option for both renovation projects and new builds.

Box balconies or box elements from Hi-Con can be installed by using different mounting principles. This type of balcony plays a significant part in the architectural expression and character of the building. 

Besides the aesthetical value of the box balcony, this type of balcony contributes with some functional values. The box balcony is both covered and closed and thereby provides the residents with a private outdoor area they can use in all kinds of weather.

As housing associations face a thorough renovation that requires new balconies, Hi-Con can contribute with unique and specialized knowledge about mounting principles and balcony solutions. We always strive to create the balconies you dream of, while still taking the construction of the building into consideration. 

Whether the balconies are meant to create a new outdoor area for the residents or preserve an already existing expression of the old balconies, we tailor the balconies to the specific project.

Balcony solutions and design

Our balconies are produced in many different unique varieties. One thing they have in common is that they are designed by you. This means that primarily the one thing that determines your concrete balcony design is you, your imagination, and the laws of physics.

When designing your customized concrete balcony, we can help guide and advise you on the dimensions of the balconies. Additionally, we are available to advise you on both the calculations of the balconies and solutions to mount your design.

Our concept balconies are a different matter. When designing your concept balcony, we have established a few design criteria that allow the price of the balcony to remain within a certain price range.   


Flexible material:

UHPC is a flexible material that allows balconies to be designed in many different shapes and sizes. Due to the material, it is possible to make the balconies slender and light, which means that the balconies do not put as big a strain on the buildings as traditional concrete.
