Volkswagen Production Plant

The investor requested comprehensive solutions with excellent durability at the best price, complying with both Polish and German technical requirements.

• Roofing - The total size of the roofing project was 394,000 m², 330,000 m² of which required roofing installation within four months. Another challenging aspect was a great number of details which made roof installation much more complex. Additionally, experience, reliability, research-confirmed durability of materials as well as comprehensive technical support were required from the building chemicals supplier.
  
  
• Flooring - The basic requirements for industry floors were to ensure cleanliness and sterility of rooms and protection of groundwater against contamination. Some rooms required also watertight floors and joints.
  
  
• Protective Coatings - About 18,000 tons of steel with a total surface area of 450,000 m² required corrosion protection in accordance with the requirements of EN ISO 12 944 standard: corrosivity class C2, expected working life: high > 15 years.
  
  
• Concete Admixtures - Some internal roads and squares were designed with concrete surface (air-entrained concrete mix). Moreover, concrete floors with surface hardening powder were designed in the production rooms.

• Roofing - on the roofs of the new Volkswagen factory in Września, Sarnafil® TS system was used which consists of roof waterproofing membrane Sarnafil® TS 77-15 loosely laid and mechanically fastened to the structural roof, vapor control layer Sarnavap® 1000E and all necessary additional accessories.
  
  
• Flooring - Sikafloor® resin floors were laid on about 90,000 m² of surface. Different flooring systems were applied depending on the requirements of the specific areas. For example, to ensure tight and chemical resistant floor, Sikafloor®-264 epoxy resin was applied offering a smooth and slip-resistant, so-called "orange peel" surface. Where necessary, antistatic resin flooring Sikafloor®-262 AS was used. Additionally, in the special cars hall, an electrostatic conductive resin with high chemical resistance called Sikafloor®-381 ECF was used.
  
  
• Protective Coatings - to achieve corrosion protection of steel structures SikaCor® coating systems were used. All coatings were applied in the workshop.The main advantages of Sika corrosion protection solutions are: quick drying time, cost-effectiveness, optimal balance of price and durability.
  
  
• Concrete Admixtures - Sika's admixtures were used for about 70,000 m³ of concrete mixes from three different manufacturers. Depending on the installation place, function, time of laying, expected performance etc., concrete mixes were designed with: plasticizers, superplasticizers, air entraining admixtures, and accelerating admixtures causing the rapid increase of the early strength of concrete.
