Car parks are an essential element of modern urban infrastructure.
Because of the heavy loads and features of use, car park flooring should meet a number of conditions that help to extend lifetime, simplify make cheaper the maintenance.
These requirements include:
- wear resistance;
- moisture resistance or hydrophobicity;
- resistance to mechanical impacts;
- chemical resistance to aggressive and toxic liquids (gasoline, oils, coolants, car detergents);
- resistance to temperature changes (when the material expands, compresses), to the so-called "zero crossing" (when water freezing in pores, as a result of expansion, can destroy the material);
- ensuring sufficient friction, traction with wheels and shoes (to avoid dangerous slipping, skidding);
- antibacterial properties (mainly antifungal);
- prevention of dust formation (especially cement dust, which is hazardous to health).
- ensuring the installation of even, seamless surface (with a slight slope to avoid stagnant water, formation of puddles).
Materials used in construction of floors for car parks
Floors for car parks are of several main types and differ both in the way of application of the protective layer and in its composition. Except for simple solutions - asphalt or concrete (based on Portland cement) without additional coating, which do not meet many of today's requirements, they are usually only taken as a base. Then they are prepared for pouring (grinding, levelling the cracks, sometimes rubbing in a special compound that fills the pores), and then filled with a polymer material to give the surface the desired properties. The following types of polymers are used:
- Acrylic (quick-drying, good at closing pores, but water-based, making them short-lived and unstable to most harmful influences).
- Polyurethane (have good adhesive properties, which is suitable for multilayer coatings).
- Epoxy (the most durable and suitable for all conditions of intensive use, well sealed pores).
After the polymer coat dries, the surface is marked, and then the final coat of epoxy varnish is applied. In order to avoid conflicts between coating components (grout and impregnation, primer, color pigments, varnish), it is desirable to choose a single manufacturer. HAUPTMANN performs the whole complex of works on pouring the surfaces of car parks in Minsk using materials of German quality, which significantly reduces costs.
