Thessaloniki shopping centre

In the parking area of a new mall in Thessaloniki, built on sloping ground, the safety of both pedestrians and car drivers needed to be ensured, avoiding stagnant water in heavy rainfall.

Α sewage disposal system was the first solution considered, but proved to be  inconveniently expensive. As a result, the surface of the parking lot was chosen to be covered with water-permeable Hydromedia™ special concrete. Hydromedia™ operates as a “shield” in heavy rain, the concrete along with the sub-base aggregates behave as absorbers. Aggregates prevent the sewer network from overloading and filter the sediments and solid particles that are carried by rainwater. It is worth noting that the concrete is strong enough to withstand the weight of delivery trucks.
