Even rather pragmatic projects such as infrastructure buildings
can be realised with care and high design standards. Their
innovative planning and high-quality realisation can have a
positive impact on our environment and significantly improve
the quality of life for people in urban and rural areas.
PIONEERING MINERAL
Transport buildings play a decisive role in the design
of our environment, as they significantly characterise
both urban and rural areas. A high standard of
design can help to ensure that these buildings blend
harmoniously into their surroundings and, in the best
case, even set new accents. The modernisation and
maintenance of infrastructure, which is necessary in
many places, offers the opportunity to set the course
for a more sustainable and efficient future. This is
not just about repairing existing damage, but also
about developing innovative concepts and realising
high-quality designs that meet current and future
requirements.
The selection of pioneering infrastructure buildings in
this brochure demonstrates high design and quality
standards, not least through the use of KEIM's mineral
product range.
PIONEERING SUSTAINABLE
KEIM made a quantum leap in terms of sustainability
in 2022 with the Cradle to Cradle Certified®
certification of over 60 products in the segments
interior and exterior paint systems and concrete
and wood systems. All products achieved silver
certification and the C2C Certified Material Health
Certificate TM Level Gold. Gold certification from the
independent Cradle to Cradle Products Innovation
Institute in San Francisco is only awarded to products
that do not contain any substances from the list of
banned chemicals and do not pose a risk to health
or the environment.

HOW WILL WE LIVE IN THE FUTURE?
MOBILITY
AND PUBLIC SPACE
INVESTMENT IN FUTURE VIABILITY
Technical infrastructures and engineering structures
are integral components of our environment and shape
it. These include not only historic railway stations and
ultra-modern airports, but also power stations, waste
disposal plants, waterways and motorways with their
bridges, noise protection systems and traffic control
facilities. More and more such facilities are being built,
and more and more areas and settlement spaces are
being shaped by them. The intelligent use of resources
and the search for holistic solutions are the basis for
long term growth and prosperity.
TRANSPORT BUILDINGS ARE ALSO CARRIERS
OF BUILDING CULTURE
The focus is currently on transport structures that
require modernisation due to an investment backlog
and structural changes that will be necessary in view
of climate change. Sustainable transport solutions
must meet our demands for mobility requirements as
well as our goals for climate protection, road safety,
quality of life and health protection. Carefully planned
and executed engineering structures can even become
central landmarks, e.g. the Golden Gate Bridge in
San Francisco, the lighthouse in Jever or the Millau
Viaduct in France.
"Infrastructure is like the DNA of a country.
A well-made road, a beautiful bridge, a great
railway station touches the lives of many people
in the country."

MTA STATION WORLD TRADE CENTER, CORTLANDT STREET,
NEW YORK, USA
Seventeen years after the terrorist attacks of September 11, 2001, the
destroyed Cortlandt Street subway station was one of the last pieces of
infrastructure to be restored. On the walls is a marble mosaic by artist
Ann Hamilton, with texts from the Declaration of Independence and the
United Nations Universal Declaration of Human Rights. A coat of KEIM
Soldalit-ME, a photocatalytically effective high-performance coating to
reduce air pollutants, ensures better air quality.

CONCRETE CHARACTER

PROTECTION AND DESIGN FOR CONCRETE
Exposed concrete is one of the greatest challenges
in construction technology. As a load-bearing and
shaping element, concrete is part of the design and
of particular importance for the architectural effect, in
particular in the case of transport structures. To protect
concrete surfaces from weather influences and dirt,
they can be treated with coatings: with hydrophobic
impregnations, transparent/semi-transparent or
coloured thin-layer mineral stain coatings or opaque
coatings.
Mineral concrete systems from KEIM protect and
accentuate concrete surfaces without changing the
character of the surface.
KEIM CONCRETAL-LASUR – FIRST CHOICE
FOR EXPOSED CONCRETE LOOK
KEIM Concretal-Lasur is recommended for transparent
coatings on concrete. Visual imperfections are
equalised and the mineral-matt concrete look is
retained – unlike with film-forming synthetic coatings.
Coloured designs are also possible, the transparency
of the mineral finish allows the moving structure of
the concrete surface to shine through.
KEIM Concretal-Black provides even deep black
façades, for particularly striking and extravagant
designs. KEIM Concretal-Lasur is absolutely UV-stable
thanks to purely mineral pigments.
PROTECTIVE FUNCTION WITH
KEIM CONCRETAL-W
Reinforced concrete infrastructure constructions such
as bridges, dams and power stations have to withstand
extreme environmental influences in outdoor
areas. With its low water vapour resistance and water
absorption coefficient, KEIM Concretal-W optimally
protects the concrete from the effects of weather and
water – and thus prevents corrosion of the reinforcing
steel. The filled version, Concretal-W-Grob, is used
as priming coat on difficult and repaired concrete
surfces. Hairline cracks are closed and structures
levelled to restore the concrete look.

ABU DHABI
INTERNATIONAL AIRPORT

AN AIRPORT AS THE GATEWAY TO THE CITY
The terminal at Zayed International Airport in the
United Arab Emirates impresses at first glance with
its roof construction: wide-span arches support a
towering, wave-shaped roof inspired by sand dunes
and geometric patterns. In order to minimise the
influence of the desert sun, the wave roof was drawn
over the façade so that less glazing is required and
external shading devices are not necessary.
"From the very beginning, our aim was for the airport to serve the emirate
and represent the city of Abu Dhabi, with a design that references the
cultural and natural environment.“
Mustafa Chehabeddine, Head of Design at KPF

ABU DHABI INTERNATIONAL AIPORT
The Midfield Terminal was designed as a gateway to the city and a
landmark for the region. The architectural firm Kohn Pedersen Fox (KPF)
developed a continuous design language for the entire project, to achieve
a harmonious overall impression.

CONCRETE DESIGN
AT STUTTGART 21
RAILWAY STATION
Architecture: ingenhoven associates, Düsseldorf
www.ingenhovenarchitects.com
Huge construction site in the heart of the city: Stuttgart 21
AMBITIOUS LARGE-SCALE PROJECT
The future main railway station in Stuttgart, designed
by ingenhoven associates and Frei Otto, forms the
centrepiece of the major Stuttgart 21 project. The
central element of the station design is the accessible
roof, half of which serves as an urban square and
the other half as a green part of the Stuttgart Palace
Gardens. The shell roof is supported by 28 chaliceshaped
columns made of white-coloured exposed
concrete. Their free-flowing, organic shapes give the
underground space a unique atmosphere unlike any
other railway station. The goblet-shaped supports
open upwards to form so-called light eyes, which
provide brightness in the hall. A shell structure in
this form has never been built before. It combines
engineering and aesthetics in an impressive way.
The construction uses very little material: in the centre
between the goblet-shaped supports, the concrete
shell is only 40 centimetres thick – with a span of
around 35 metres.
DEMANDS ON EXPOSED CONCRETE
As usual, after stripping the formwork, the concrete
did not yet show the perfection that would later
characterise the impression of the room. In some
places, the formwork panels had slipped slightly
against each other, so that the concrete surfaces had
projections and recesses of a few millimetres. As the
goblet columns are always bathed in glancing light
from above, these unevenness cast shadows were
particularly noticeable. The very heterogeneous
surface qualities of the concrete did not meet at all
the architects' demands: Sometimes matt, sometimes
slightly shiny, sometimes discoloured. It was therefore
clear that the surfaces needed to be touched up:
A total of around 60,000 square metres of exposed
concrete and almost 100 kilometres of joints were
treated with KEIM's mineral product range.

STUTTGART 21 MAIN STATION
The new concourse at Stuttgart Central Station is a masterpiece of
engineering. The freely curved shell roof is nearing completion: the
concrete surfaces are carefully finished to emphasize the elegance of the
flowing forms. The company beconart relies on KEIM products for this.

ARCHITECTURAL MASTERPIECE
IN CO-OPERATION
The largest and most important airport in Spain was
designed by the Spanish architect Antonio Lamela
and his British colleague Richard Rogers and is one of
the most spectacular airport buildings ever. The main
terminal of the ultra-modern 120,000 square meter
building is divided into three levels. A huge roof spans
above it, supported by steel trees. The architectural
masterpiece was awarded the "architecture Oscar",
the Stirling Prize 2006.

GRIMMING BRIDGE
TRAUTENFELS, AUSTRIA
SECURE CONNECTION
The 135 metre long Grimming Bridge is part of the
newly designed Trautenfels traffic junction.
The structure was built as a slender five-span, integral
frame bridge in reinforced concrete construction.
Bearings and conventional roadway transition
structures were not used. The deformations of the
structure are absorbed by Ultra High Performance
Fibre Reinforced Concrete (UHPFRC) slabs at the ends
of the bridge in such a way that the road is not
damaged. The material is an ultra-high-strength
concrete reinforced with special fibres.

BOBER VIADUCT IN BOLESLAWIEC, POLAND
The 489 metre long viaduct was opened in 1846 as a railway bridge
between Berlin and Wroclaw. The bridge is predominantly made of stone.
During the refurbishment, not the entire surface was coated with KEIM
Concretal-Lasur, but only the 20 % of the surface that was filled with
concrete and cement mortar. The refinish imitates the stone.

BETTER MINERAL
Whether public, cultural, listed or infrastructural
buildings: KEIM paints fulfil aesthetic, health and
building physics requirements in equal measure and
have stood for lasting values for over 145 years.
Countless objects all over the world testify to the
unique quality of the products. They owe their unrivalled
durability to the adhesion principle of silicification.
The chemical bond, the "silicification" between binder,
substrate and pigments is extremely durable.
HEALTHY INDOOR CLIMATE
In addition to traffic-related and functional aspects,
infrastructure buildings such as railway stations,
airports or terminals also place high demands on the
design and quality of the interiors. Interior paints from
KEIM create an attractive colour design and ensure
a healthy indoor climate, as they contain no added
preservatives, solvents or plasticisers. They also
effectively prevent mould and are non-flammable,
which means that the paints do not emit any toxic
gases in the event of fire!
FAÇADES WITH LASTING VALUE
When it comes to durability, KEIM exterior paints are
unrivalled. They fulfil the highest requirements in terms
of building physics, weather resistance, economic
efficiency and environmental compatibility.
With KEIM Purkristalat, KEIM Granital, KEIM Soldalit,
KEIM Unikristalat and KEIM Twinstar, KEIM offers the
perfect exterior paint for every field of application –
durable, lightfast, UV-resistant, economical and
environmentally friendly. KEIM Soldalit-ME, a
photocatalytically effective high-performance coating
for the reduction of air pollutants such as nitrogen
oxides, ensures a "portion of good air".

HISTORIC RAILWAY
STATIONS IN COLOUR
CHANGING WITH THE TIMES
Railway stations have always been gateways to
the world and important places of urban identity.
In the 19th century, the railway station was an
important type of architectural building, a symbol
of modernity, urbanity and industrialisation. Station
buildings were the cathedrals of the industrial age
and played an important role in the development of
modern architecture. Just like parliament buildings,
opera houses or town halls, railway stations have
also become important landmarks.
Colour was and still is an important design element,
especially in the context of refurbishments. With
its core expertise in mineral building protection,
KEIM is the right partner here too.
