The Crack Inducing Waterstop profile is produced by Primostar Tootmine OÜ and manufactured in Estonia. The profile's creator is Indrek Uusalu, who is both the founder and CEO of Primostar Tootmine OÜ, as well as the CEO of Primostar OÜ.

Primostar's Crack Inducing waterstop profile controls shrinkage cracks, ensuring the planned shrinkage crack is immediately waterproof and located in the desired position. 

The crack-inducing waterstop is characterized by its  Z-shaped galvanized steel plates, which result in a Load-bearing watertight binding keyway-shaped shrinkage crack that does not weaken the construction. Additionally, the profile has been patented in the USA and Estonia and holds an Environmental Product Declaration (EPD), which is particularly significant in today's sustainability-focused world. The profile has been on the market for five years and has been used in Latvia, Lithuania, Ukraine, Finland, Turkey, and, of course, on construction sites in Estonia.

The Crack Inducing waterstop is part of the white tank waterproofing solution for underground, reinforced concrete construction that waterproofs the construction without using an external membrane. This solution is unique because it is invisible to the eye, as the entire waterproofing remains hidden within the structure.

In a short time, we have been offering the white tank waterproofing solution, and by 2024, we have managed to save nearly 6.5 million kilograms of waterproofing materials.

Let's build more sustainably and economically together to make the future greener!
