A roof overhead. But will your parking space stay dry?
Primostar® Crack Control System

We rarely think about this when we park. But when water starts dripping from the parking garage ceiling, an invisible construction detail becomes very visible.


A dry parking space starts with details that a driver usually doesn't see. At Lahekalda’s semi-open car park, one such detail is the Primostar® Crack Control System profiles embedded in the concrete Intermediate Ceilings.


The profiles serve two purposes:

✔️ Direct concrete shrinkage cracks to planned locations.

✔️ Ensure the watertightness of controlled cracks.


This way, the concrete's natural behavior is accounted for during construction, and waterproofing becomes an integral part of the structure.
