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.
