The goal in a concrete floor slab is not to fight the natural behavior of concrete.
A good solution helps it happen in a controlled way, not randomly.

Primostar® Crack Control System helps direct shrinkage cracks exactly where they are intended to occur, ensuring the waterproofing performance of the structure.


✔️ Waterproofed and controlled cracking.

✔️ A system that works with concrete — not against it.

✔️ Fewer risks.


Because a good solution does not prevent the natural behavior of concrete. It controls it.
