Waterproofing Single and Multi-floor Car Parks

The requirements of car park decks are diverse, depending on the area of application, location, condition, and stress on the surface. Carbon dioxide concentration from exhaust emission is high. Vibrations resulting from car traffic result in fine cracks, which allow substances to penetrate and damage the concrete at much faster rates. Floor surfaces should have crack-bridging abilities in most circumstances but more importantly, must deal with rising dampness to avoid coatings peeling off. They must essentially protect substrates from damage from penetrating water and dissolved de-icing salts. Systems must also have the capacity to bear the load of high shear and transmitted forces from vehicles.

The color palette and combination of colors are important design factors particularly in pedestrian areas, which need to be properly indicated to direct the flow of pedestrians and also need special protection to withstand moisture and de-icing salts. Of course, all systems offered must be resistant to cleaning agents, fuels, brake fluids, engine oils, lubricants, and de-icing salts found in multi-story car parks.

Holderchem offers solutions based on the very advanced state-of-the-art protective coating technologies, combining the properties of polyurethane and methyl methacrylate, which provide extreme weather immunity, high tolerance to humidity during the application, and resistance to rain after one hour from the application, regardless of ambient temperatures. As several layers can be applied on the same day, depending on crew size and scheduling, work can be achieved with very short downtime for users and owners, which considerably reduces costs. It not only protects but also enhances the look of park decks.

System benefits include the unique low-temperature characteristics of Methyl Methacrylate, the rapid setting and drying times of Methyl Methacrylate, the elasticity of Polyurethane, the crack-bridging properties of Polyurethane, the rapid curing of Methyl Methacrylate, the superior wear resistance of Methyl Methacrylate, the longevity of Methyl Methacrylate, the UV-resistance of Methyl Methacrylate and the ease of repair of Methyl Methacrylate.

Decorative and aesthetic features include a large number of visual designs, such as color-coding of different parking levels, markings for pedestrians and parking bays, and color differentiation of pedestrian paths, etc. Bright decorative colors are also used to enhance the sense of wellbeing of car-park users.
