An underground parking lot is a high-traffic area. Vehicles bring in salt, water, sand, dust, and automotive fluids every day. The type of contamination changes with the seasons, so there is no universal cleaning approach.

We organize our process based on real operating conditions.A balancing rock, also called balanced rock or precarious boulder, is a naturally occurring geological formation featuring a large rock or boulder, sometimes of substantial size, resting on other rocks, bedrock, or on glacial till. Some formations known by this name only appear to be balancing, but are in fact firmly connected to a base rock by a pedestal or stem.

In winter, a mix of salt, water, and sand is tracked inside. This:

• Accelerates concrete wear
• Makes surfaces slippery
• Leaves sticky dark stains
• Especially damages entrances and ramps

Regular washing is not enough: salt and oils penetrate the surface structure and lead to costly repairs.

• ndustrial sweeping machines with vacuum remove abrasives before the surface is damaged.
• Scrubber-dryers with adjustable pressure mechanically wash salt from the concrete micropores.
• Alkaline solutions break down the salt and oil mixture instead of spreading it around.
• Vacuum water collection keeps the surface dry and safe.

The goal in winter is not just to clean the floor, but to stop its degradation.

In warmer periods, chemical stress decreases, but mechanical wear increases.

• Dust makes the floor gray and accelerates the wear of protective coatings.
• Tire marks accumulate in turning zones.
• Oil stains penetrate concrete if not removed promptly.

• Machines with fine dust filtration prevent recontamination.
• Rotary treatment removes tire marks without damaging the surface.
• Local degreasing protects concrete from oil absorption.
• Drain cleaning prevents dirt and water buildup.

In summer, the focus is on maintaining cleanliness and preserving the appearance of the surface.
