Carpark

The German OS system of grading floor surface protection is widely recognised internationally. OS 8, OS 10 and OS 11 coating systems are designed to protect the reinforced concrete decks and floors of multi-storey and underground car parks from the effects of moisture and reinforcement corrosion. Complying with these grades, the car park systems of the MC-DUR product line are non-slip, easy to clean and, with proper maintenance and care, will last for decades. And our new KineticBoost® coatings are also particularly quick and safe to apply, as well as being highly resistant to abrasion.

Contamination caused by the absorption of de-icing salts in the original concrete of floors, columns and wall bases is often rectified in car park maintenance campaigns by using concrete replacement systems from the Nafufill product family. This renews the corrosion protection of the reinforcement, prevents future penetration of de-icing salts and enhances the load-bearing capacity and fire resistance of the treated components.

In multi-storey and underground car parks, structural elements, large concrete areas and concreting sections are separated by joints to prevent cracks occurring in the structure. The joints must be made watertight to protect both the reinforced concrete and the user vehicles themselves from corrosive fluids. For this purpose, MC offers flexible sealants from the Mycoflex product line and MC-Floor Connect joint profiles, which have been specially developed for multi-storey car parks.

Cracks in the floor and deck slabs of multi-storey car parks must be sealed to protect the reinforced concrete from de-icing salt. In underground car parks, the sealing of movement joints as well as wall connections is likewise essential. Polyurethane and hydro-structure resins of the MC-Injekt brand boast a proven, decades-long track record in such waterproofing applications, making MC-Bauchemie the global market leader in injection technology.

CFRP straps and sheets enable the load-bearing capacity of components in purpose-built car parks to be retrospectively improved or even completely restored. Tested and approved composite materials made of carbon fibres and synthetic resin adhesives from the MC-CarbonFiber and MC-CarboSolid product lines are extensively used for this purpose.

Surface protection systems of the MC-Color product family for columns, walls and ceilings safeguard the reinforced concrete in car parks by preventing carbonation and protecting against spray water containing de-icing salts. In addition to these technical objectives, they enable differentiation in the colour design of the individual levels so as to facilitate wayfinding for users. Surface protection systems in light colours also increase users' sense of security and save on lighting energy.

Before applying the coating system to the floors in a parking garage or underground car park, the substrate must be prepared. This is usually done by blasting or grinding. This cleans and roughens the base layer in order to achieve a durable bond between the reinforced concrete and the coating and to ensure the long-term function of the entire floor structure.

The floor coating of a multi-storey or underground car park is applied in a series of separate work stages. After surface preparation and priming, depending on the specification, a scratch coat and a crack-bridging membrane are installed. Finally, one or more wear layers are applied. The result is a resilient and impermeable coating system capable of affording decades of protection, safeguarding the concrete from penetrating fluids and its reinforcement from corrosion.

In multi-storey carparks, the individual levels are mostly connected by ramps. Particularly when braking and accelerating the cars, high loads act on the floors of the ramps. That is why the coating systems applied on the ramps need to be highly robust and resistant.
