Our transport infrastructure - roads, streets, pedestrian areas, bridges and railways - has to cope with increasing traffic and urban life. Downtime on these essential infrastructures whether for new construction or maintenance work causes delays and diversions leading to traffic congestion. Durable, fast construction solutions help to minimize this negative impact.
1. Manhole & Utility Box Covers
Manhole and utility box covers are the passage to a whole substructure in cities that includes energy, sanitation, water and communication infrastructure. It is not uncommon that these covers are placed underneath trafficable areas - in which case high dynamic loads can lead to fracture and unsafe roads. To avoid traffic jams, Sika offers fast solutions that can be placed in between different materials, cope well with the surrounding asphalt and are suitable for cold temperatures.

Applicators specializing in manhole or utility box cover repair often also have to repair the inside of manholes. See Sika's sewage and waste water treatment plant solutions.
2. Streetscape Pavement (Trafficable)
Today, streetscape pavement for light and heavy traffic is often used as an architectural expression within urban landscapes. With increased traffic load and longer life expectancy, a new approach was required for materials and system build-ups. That’s why Sika has designed a complete range of mortars and products dedicated to the installation of paving stones on roads. This offer complies with numerous standards in force (such as NF, UNI, etc.) and is based on a bonded system of laying mortars, jointing mortars, and auxiliary products for transition zones. Example applications include expansion, movement and splitting joints and the installation of urban furniture.

Sikadur®-31 Mortar for bonding of curbs or urban furniture
Sika Latex® Adhesive agent for cementitious bonding
3. Landscape Pavement (Non-trafficable)
The build-up of pavement for landscaped, non-trafficable areas differs from zones with vehicular traffic, in that a bigger variety of paving stones can be laid on gravel and sand in an unbound system. Vibrating plates are required to compact the system. The application is easy and cost-effective. For long term durability and aesthetic design, special consideration needs to be taken on the paving stone joints to resist against vegetation, material wash out, point loads (e.g. high heels) and other impacts.

4. Rail Fixing
Transport systems have changed in our modern world. In the city center for example, we have new tramway lines which have to be well adapted to traffic constraints as well as interconnected crossroads that require perfect management of various foundation types (e.g. asphalt, concrete, bitumen and steel rail).
Sika has developed a specific range of products to be poured between and underneath the rail and bitumen, paving stones or concrete roads, which can also reduce noise and vibrations caused by trams.

5. Movement Joint Sealing
Movement or expansion joints in pavement are typically placed at intervals around 5 meters by 5 meters. They are used in trafficable areas for vehicular traffic, for train or tram rails or for material or zone transitions (connection to houses, manholes, etc.). These joints must often be sealed to protect against moisture build up and freeze-thaw impacts, while allowing for movement.

6. Street Furniture, Pole & Signage Fixing
Road and rail infrastructure requires the fixation of poles for power, lights and traffic signs, stops for public transport, bicycle stands and other elements. Recreational zones and green spaces require benches as well as bollards or fences to delimit areas. Billboards are fixed for commercial reasons, and water connections like hydrants for safety reasons or hot weather. All these elements fall under the category of urban furniture. Sika is able to offer a range of products and mortars suitable for the rapid, durable sealing of many such installations.

7. Anti-Graffiti Coating
Less asphalt in the cities, beautiful clean spaces, highlighting of magnificent buildings - in a few words, this is the increasing desire of people living in cities to return to natural beauty.
To preserve the appearance of these different urban elements and protect them from vandalism, graffiti or unsolicited advertisements (e.g. fly posters), Sika has developed a permanent, anti-graffiti coating system. It is particularly effective, easy to clean and respectful of the environment - graffiti removal requires only water. No more costly or unsightly restoration work on magnificent monuments, subways and building facades. Watch the video below.

8. Bridge Deck Expansion Joint
A bridge deck needs to be decoupled from the connecting road and columns to allow for thermal expansion and contraction, seismic movement, dynamic loads and other movements of the bridge. This is done by constructing a bridge deck expansion joint.
Such joints often must also prevent de-icing chemicals or other corrosives from penetrating into the substructure. They are highly exposed and are one of the first components that can fail on a bridge, possibly leading to dangerous traffic accidents and long traffic jams. Thus, an early and fast repair for expansion joints is critical for an improved urban area experience.
Using Sika® FastFix-138 TT for bridge deck expansion joint repair allows for a fast return to service (within a few hours) and for easy application even at low temperatures.
To reduce high maintenance cost, implementation of a durable solution like the EMSEAL bridge expansion joint system (BEJS) is recommended for new construction.
Another Sika product, Sikasil®-728 SL, is designed to seal saw cut and expansion joints in pavement not only on bridges, but also on highways, airports, garage driveways and car park top decks.
Recreation zones in cities with increasing population growth require long-lasting solutions for aesthetic design, combinations of different materials, noise reduction and protection against vandalism.
Sika offers solutions for every type of project in urban development, landscaped areas and rail transport in order to make these spaces pleasant, user-friendly and much more sustainable than in the past. We promise that it pays off to look at the solutions Sika has to offer.
