12 Sika Solutions for Floors in Car Parks Car park flooring systems have many different requirements ranging from deck waterproofing and wear resistance to design possibilities. Sika has a wide portfolio of Sikafloor car park systems specially designed for all of these different applications and requirements. The systems are based on epoxy technologies for the hard wearing surfaces and polyurethane resins for crackbridging and waterproofing. From a technical point of view, the main function of these Sikafloor deck systems is to protect the reinforced concrete structure and prevent the ingress of water and corrosive de-icing salts. Therefore, crack-bridging properties are frequently essential to accommodate the thermal and dynamic loading movement of the structure, especially on composite structures and in exposed areas. Ramps usually require the system to have a higher degree of slip resistance, plus they are much more exposed to mechanical stress, which the Sikafloor systems can easily accommodate. Sikafloor car park deck waterproofing systems can be designed to the colour and area demarcation scheme of your choice. A bright and well-lit car park helps to improve safety and security, plus this also makes the visitors feel more comfortable. In car parks floor the joints can be sealed with Sikaflex sealants, which are able to resist traffic loads from the cars and cleaning machines passing over them. They will retain their properties in direct contact with oils and fuel, and withstand the weathering when used externally. Sikaflex sealants have high mechanical strength, high abrasion and chemical resistance with excellent substrate adhesion in the joints. Typical Applications Sika Solutions Special Performance Flooring in multi-storey and Sikafloor -263 SL / 264 Epoxy based, slip-resistant wearing surfaces with high abrasion and impact resistance. underground car parks Sikafloor -350 N, 359 N Polyurethane based, deck waterproofing and wearing surfaces with high abrasion resistance and crack-bridging properties. Sealing of car park floor joints Sikaflex PRO-3 High performance 1-component sealants based on Sika s i-cure technology with outstanding mechanical and chemical resistance.

13 Kloten Airport, Zurich, Switzerland Project: For many years Sika has been the reliable supply partner of this important airport during its continual expansion, upgrading and refurbishment programmes. Sika solutions have been provided from the basements to the roof. Sika solutions: Sika Concrete admixtures including the latest Sika Viscocrete technologies have been used to produce special concrete mixes for both precast and site placed concrete all around the airport terminals and the air-field. Sika Sarnafil roofing is applied extensively on the airport building roofs and waterproofing in below ground areas such as transport tunnels and baggage areas has been successfully completed with Sikaplan membranes. The airport car parking structure floors used elastic Sikafloor systems for waterproof crack-bridging in critical areas of high wear resistance, particularly where there is also movement anticipated. Special Sikafloor systems were also used in highly trafficked areas such as the entrances to the connecting bridges, the driving lanes were demarcated in black, the parking bays and the pedestrian areas were also given non-skid and non-slip finishes. SikaCor systems are used for long-term protection of the structural steelwork against corrosion. Sika has provided solutions for concrete repair and refurbishment including damage caused by exposure, chemical attack or mechanical impact to runways and facades. Recently Sika solutions have also been selected for waterproofing for the new waste water and sewage treatment plants. 12 I 13

14 Rizon Jet Hangar, Biggin Hill Airport, Kent, United Kingdom Project: A new multi million pound private jet aircraft hangar with a floor area of m 2. Sika solutions: A robust and abrasion resistant floor with a very high quality finish was required and this was provided using Sikafloor EpoCem applied as a damp-proof membrane, followed by a Sikafloor 3 mm self-levelling system. Walkways were marked with Sikafloor coatings and given a matt finish. The kitchen and catering areas had a 9 mm screed of Sikafloor Purcem. Battery rooms were protected with a Sikafloor chemically resistant and anti-static system. Workshops and other areas were sealed and protected with Sikafloor coating systems. Additionally the hangar floor joints were all sealed with Sikaflex sealants and the structural steel column bases were grouted with SikaGrout.

15 Sika Solutions for Floors in Aircraft Hangars Aircraft hangars are principally garages and maintenance workshops for aircraft. Leaking hydraulic oils, cleaning chemicals and high mechanical loadings can all attack and damage the floors. Protection of the workforce with regard to preventing slips and falls with ade quate slip resistance, discharging static electrical charges to prevent instrument malfunction or even explosion in the event of a spark, can all be additional special requirements for hangar floors. Therefore a range of different solutions and systems could be required. Sikafloor flooring systems for hangars can accommodate the heavy loads in addition to allowing freedom of floor surface design and fulfill all the requirement mentioned above. Easy cleaning and low maintenance costs with a long service life are also the essential performance of Sikafloor for the optimum hangar flooring solutions. As Sika systems are selected according to each area s specific needs, the Sikafloor systems will be durable and maintain their good appearance; whilst satisfying the health and safety criteria for the maintenance personnel. These Sikafloor solutions are 100% solids and solvent free, which also helps to ensure worker safety. They are fast curing, which puts the aircraft hangar back into service with an absolute minimum down time. The Sikafloor system technologies are based on epoxy and polyurethane resins. The defined system build-ups are then tested accor ding to many different standards regarding H&S, including AgBB, etc., which also serves to underline Sika s strategy to be the leading flooring company with regard to sustainability. In hangar floors the joints can be sealed with Sikaflex sealants, which also resist the loadings from aircrafts and maintenance machines. They will retain their properties in direct contact with oils and fuels. Sikaflex sealants have high mechanical strength, high abrasion and chemical resistance plus excellent adhesion within the joints. Typical Applications Sika Solutions Special Performance / Functions Flooring hangars Sikafloor -263 SL / 264 Epoxy based, slip resistant wearing surfaces with high abrasion and impact resistance.

16 Sika Solutions for Floors in Freight, Logistics and Food Processing Areas Airport freight handling and other logistics areas include: warehousing, loading bays, ramps etc., where the floors must be extremely abrasion and wear resistant due to the heavy traffic, plus the areas must also be dustfree and easy to clean. Sometimes these floors can require additional chemical or fire resistance, antislip properties, resistance to extremes of hot or cold temperatures and other specific performance demands, according to the function of the areas. Sikafloor Deco Floor systems are certified to fulfil the specific needs of these fright and logistic areas and they have high aesthetic appearance. Sikafloor Deco Floor systems are based on low emission, UV resistant, high performance epoxy resins that are tested according to the stringent out-gassing procedures of the German AgBB scheme. Their surface finishes can be adjusted from smooth to highly slip resistant for safety and allow individual and decorative floor designs. These can also be used in commercial and retail areas, including restaurants baggage claim and all of the logistics areas in an airport. Sikafloor solutions for food processing areas are designed to protect concrete floors with an appropriate seamless and hygienic coating. In food areas the floors are typically exposed to all sorts of food products, including drinking water, hot oils, sugars and fruit acids, plus wide variations in temperature, exposure to cleaning agents, etc., which could all cause serious damage to unprotected concrete surfaces.these aggressive materials can also penetrate into the concrete surfaces, resulting in the growth of dangerous bacteria. Polyure - thane resin modified cementitious screeds, such as Sikafloor PurCem systems, are fully resistant, durable and therefore ideal to meet all of the individual requirements. To make the floor finishes seamless and joint-free, Sikaflex sealants are used to also seal the move ment and connection joints in all of these floor areas. These have high mechanical and chemical resistance, prevent dirt and bacteria build-up, are easy to clean and fully resistant to cleaning agents and cleaning machines. They cure bubble-free and are easy to apply.

17 Phuket International Airport,Thailand Project: This is the second busiest airport in Thailand in terms of passenger numbers, as Phuket is one of the most popular resorts and tourist destinations in the country. Sika solutions: Sika provided Sika Deco Floor systems for the floors in the baggage claim areas and the arrival areas to fulfil the requirements that included: being dust-free, with good resistance to mechanical abrasion and heavy foot traffic, ease of cleaning, plus the floors also had to be comfortable underfoot for standing passengers. Sika Sarnafil roofing membrane systems were also used for the terminal building roofs at the airport. 16 I 17

18 Nike Store, Thessaloniki, Greece Project: This Nike store is in the Mediterranean Cosmos Mall, located east of Thessaloniki adjacent to the airport. This mall is currently the largest in Northern Greece, consisting of 220 stores, plus 37 restaurants and cafes. This particular floor s requirements were for it to have an athletic look that fits with the Nike brand, it had to be installed and finished in 5 days, be pleasant underfoot for the customers, easy to maintain, easy to clean, and of course tough and resilient enough to withstand a lot of pedestrian traffic and still look good. Sika solution: The flooring solution selected to fulfil all of these requirements was a Sika Comfort- Floor system this produces a permanently elastic, polyurethane resin based floor. It is solvent free with very low VOC emissions, easy to maintain and has good mechanical resistance to withstand heavy pedestrian traffic. This Sika resin flooring system was combined with a wooden area in the centre of the store.

19 Sika Solutions for Floors in Public and Commercial Areas Sika has developed Sika Comfortfloor and Sika Deco Floor systems as durable and decorative flooring solutions especially for use in the different public and commercial areas of an airport including retail and shopping areas, passenger lounges, restaurants and offices, because these areas has requirements like high aesthetic floor surfaces, sound damping property, good indoor quality with lowest class of VOC emissions, according to guidelines and regulations, comfortable underfoot experience, easy to clean and maintain, etc.. These Sikafloor ranges can have various system build-ups where different coloured resins are combined with decorative coloured flakes and aggregates, which allows the customers to create many attractive and individual finishes incl. extend the corporate identity onto the floors. This Sika Comfortfloor and Sika Deco Floor range has been tested and approved to the most stringent global standards for VOC emissions including LEED, AgBB, AFSSET, M1 etc., plus they also have the lowest fire ratings.

20 Sika Solutions for Steel Structures Functionality and flexibility are key design factors for the owners, their architects, and the management of airport terminals and hangars. Structural steelwork is generally the most suitable material to create these wide-span structures. However, the steel structure has very high demands not only for its function and aesthetic appearance, but also for its fire protection property. Sika has therefore developed specific coating systems combining fire protection and aesthetics. Sika Unitherm is an ideal solution and its performance is backed up by extensive references at airports and other public buildings. Sika Unitherm fire protection systems are intumescent coatings, which are typically applied in layers from mm thickness. They expand in fire situa tions to create an air filled insulation layer to protect the steel from high temperatures, which could otherwise result in structural failure. For exposed areas of structural steelwork, where the focus is on protecting the steel against corrosion, the SikaCor range provides durable coating solutions for all types and levels of corrosion exposure. Sika s steel protection technologies are based on epoxy, polyurethane and other modified resins and the systems are available in an almost unlimited colour range to suit your design. This Sika range also includes many products for special application and they are developed with low VOC emissions and as high-build systems to reduce application time and costs. Sika has a proven global track record and has achieved success in the protection of prestige steel structures all over the world on many different airport buildings and facilities. Sika systems also comply with the latest relevant standards including ISO for steel corrosion protection. Typical Applications Sika Solutions Special Characteristics Structural steel SikaCor Steel Protect VHS Multi-purpose coatings for the corrosion protection of steel structures. Transport structures Sika Poxicolor Plus Very economic and durable corrosion protection coatings with low solvent content.

21 Dubai International Airport, United Arab Emirates Project: In phase II of this major airport development, seven Emirates aircraft hangars were also built for their aircraft service and maintenance, including their paint shop and large enough to accommodate all of the specialist functions and personnel required for this sophisticated operation large enough in fact to be used for their fleet of giant Airbus A 380 aircraft. Sika solutions: The structural steelwork for the hangars had to be protected against fire for a minimum of 60 minutes. This high performance fire protection was provided by the Sika Unitherm system. The structural steel on the pedestrian bridges from the terminal to the airplanes was also coated with the same system. The technical workshops needed to have wall surfaces with minimal VOC / AMC or particle emissions, therefore Sikagard coating systems were applied on all of these walls to meet the necessary standards, plus the Sika Permacor system was used for the interior coating and lining of the drinking water storage tanks (approved for potable water contact). 20 I 21

22 Airfield & Runways, Kloten Airport, Zurich, Switzerland Project: For many years Sika has been the reliable partner to the owners and their professional construction teams in the expansion and refurbishment of this important airport in Switzerland, with Sika support from the basement to the roof with a full range of specialist solutions. Sika solutions: Sika ViscoCrete technology and many other Sika concrete admixtures have been used extensively for the airfield concrete production, in order to create the majority of all of the different structures on the airfield for the runways, taxiways and aprons. Sika has also provided SikaCem, Sikadur Pronto and SikaAntisol for the repair and refurbishment of the concrete runways over the decades. The joints on the runways were sealed also with Sika sealants.

23 Sika Solutions for Airfields Sika provides admixtures to produce high-performance concrete for runways, taxiways and aprons at airports that has to meet very specific requirements. These large surface areas are fully exposed to heavy rainfall, intense frost, ice and snow, with frequent thermal shock conditions, plus high impact and abrasion stress. In addition, strong de-icing agents are used, frequently with heavy duty mechanical ice and snow clearing machines. This further increases the demands on the concrete and especially on the edges of the slabs. Aircraft traffic areas at airports are almost always now laid with concrete paving machines. These handle the relatively stiff concrete mixes with a low water cement ratio. Sika ViscoCrete technology is used for to maintain consistence with this high level of water reduction. SikaAer is added to give the concrete increased frost resistance, plus with SikaRapid technology, high early strength is achieved. With these concrete mixes the shape of the fresh concrete is maintained more effectively and greatly increased flexural strengths are also obtained. SikaFume is used to increase pozzolanic reactions at the micro-level of the aggregate / hydrated cement contact zones, especially with crushed stone aggregates. After placement these concrete surfaces are protected against premature drying out through evaporation with Sika Antisol curing compounds. The skid resistance of the surface can also be improved by an exposed aggregate finish created with Sika Rugasol. When airfield concrete needs to be repaired, Sika also has excellent refurbishment solutions. Time is of the essence when repairing spalls, cracks and damage on airfields which are still in daily use. In most cases, there are only a few hours during the night to carry out these repair works. Sikadur Pronto mortars are fast curing, two part acrylic resin based systems that are ideal for repairing runway damage. After the area is prepared by removing the deteriorated material and thorough cleaning, the Sikadur Pronto mortar is placed. The repair areas can also be fixed mechanically to the substrate with steel anchors to prevent any uplift possibilities. These repaired runway surfaces will be cured and ready for the first take-offs and landings in the morning. To seal the joints on airfields and taxiways, Sika has developed special Sikaflex sealants with high tear resistance and flexibility, plus resistance to heavy mechanical stress and exposure to aircraft oils and fuels. Typical Applications Sika Solutions Special Characteristics Water reducing admixtures Sika ViscoCrete Highly efficient superplasticizers based on polycarboxylates.

24 Sika Solutions for Concrete Structures Concrete structures and elements make up the major part of airport buildings and structures. Sika provides admixtures and additives that have been developed to support the production of high quality concretes for these structures. Watertight concrete is frequently important, because airports are often located in wide flat areas where the ground water level can be very high. In addition, there are large paved areas which are exposed to heavy rainfall and flooded with surface water. Sika ViscoCrete and Sika WT concrete admixtures produce watertight concrete that is ideal for the construction of watertight basements and underground facilities such as car parks and transport system tunnels. For durable precast concrete elements such as pillars, tunnel segments, Sika ViscoCrete and Sika Rapid technology is used to ensure their optimum rates of production and gain of strength, plus high quality units with an excellent surface finish are obtained. Airport buildings usually have huge dimensions, especially the terminal check-in and baggage reclaim areas for example, so the large areas of concrete in these structures can be susceptible exposed to high shrinkage. The use of Sika Control technology can be used to restrict and control this problem. From an aesthetic point of view, airport buildings are always architecturally challenging projects. Through the use of Sika PerFin and Sika ColorFlo, a wide range of attractive coloured concrete surfaces and textures can add to your design possibilities. Typical Applications Sika Solutions Special Characteristics Water Reducing Admixtures Sika ViscoCrete Highly efficient superplasticizers based on polycarboxylates.

It is a state-of-theart international airport complex with first class shopping, restaurants, entertainment facilities and full services for airlines and their passengers. Sika provided a full range of systems to produce high performance concrete and many other specialist construction solutions for this airport project. Sika solutions: Sikament concrete admixtures were used to produce the concrete piles, the reinforced concrete elements of the superstructure and the floor slabs; Sika ViscoCrete technology was used to achieve a concrete strength of C35 at 72 hours for defined areas; Sika WaterStops were cast into the concrete for sealing the expansion joints; Sika Separol de-moulding agents were used where steel formwork was utilised. Sikadur adhesives were used for anchoring steel bars and bolts for structural steelwork. Cement based non-shrink SikaGrout was used to grout the column bases and other areas on the structure. The Sika Carbodur strengthening system was used to increase the design load bearing capacity of some elements. Sika Ceram adhesives were used for laying the terminals sandstone floor tiles. Sika Monotop mortars were used for localised concrete repairs as the works progressed and were finished to the correct line and profile; plus SikaTop mortars were used for the protective coating of drinking water storage reservoirs. Sikaflex PU sealants were used for horizontal joint sealing between concrete and asphalt surfaces, with Sikasil silicone sealants used for sealing between granite and aluminium materials in the terminals; plus Sikasil SG systems were used for structural glazing of the airport terminal structures. 24 I 25

27 Sika Solutions for Building Facades Modern airports are increasingly designed with large areas of glass and metal facades. The durability and appearance of curtain walling and other full and partially glazed structures are highly dependent on the use of the right structural glazing adhesives and weatherproof sealants. Sikasil SG systems are well established structural glazing adhesives which have been used to create many airport facades around the world. Sikasil SG structural glazing adhesives can accept 30% higher design loads, which allows slimmer profiles and maximum transparency. For insulated glazing units (IG units), Sika provides Sikasil SG secondary sealants. For highperformance Argon-filled insulating glass units, Sikasil IG-25 HM Plus with annual Argon loss rates as low as 0.2%, has become a bench mark in this Industry. For joints between different single glass elements, between insulating glass units or between glass and metal frames, Sikasil WS weatherproof sealants fulfil all of the requirements. They have high elasticity and flexibility, excellent adhesion to glass and metal, superior UV light stability, outstanding weathering resistance, and full compatibility with Sikasil IG sealants and SG adhesives. For concrete facades, tight joints are the key to durability and energy saving. Sika Sikaflex joint sealing solutions for these movement and connection joints in concrete facades have the proven performance to meet all of the requirements. These include high tear resistance, low modulus even at low temperatures, excellent weathering resistance, high UV resistance and colour stability, good adhesion to both porous and non-porous substrates, over-paintability, etc.. For the glazed balustrades of external visitor s platforms, or internal glazed partitions, the glass panels should be fixed to the floors with minimal stress transfer into the glass. With the elastic, damping SikaGlaze GG system the bottom glass edge is securely embedded in the floor, or in metal U-channels, resulting in uniform stress distribution and minimal stress transfer to the glass.
