The customer's needs
The Auchan shopping centre in Luxembourg is the largest and busiest in the country. The building also houses offices of the European Commission. The car park is used daily by 35,000 vehicles on 4 underground levels.
The constraints
Renovation involved 56,000 m2 of flooring and 85,000 m2 of walls. In the meantime, the shopping centre had to remain open 7 days a week and the car park accessible to customers.
The enormous ground surface was asphalted and cracked in many places. The option of removing it before constructing a new one was out of the question.
4m Group's solution
4m Group carried out technical research and tests for 2 years in order to propose the best solution to the customer.
First, the cracks were sanded and filled with Flowcrete polyurethane.
Then 4m Group applied a polyurethane primer, a Deckshield elastomeric PU membrane, a PU base.
The top surface was finished with Flowcrete Deckshield Terminer. This solution increases the anti-skid and reflective properties of the surface to provide greater safety and comfort to users.
The final result is a safer, more resistant car park floor that is easier to maintain.
The 4m team consisted of 15 to 35 professionals who, depending on the phases, worked 24 hours a day, 7 days a week in shifts. Work on the site was spread over 4 months with a minimum of disruption of activity for the shopping centre.
