OM FÖRETAGET
Vi har specialiserat oss på vattentätning av betongkonstruktioner under mark i mer än 20 år. Under denna tid har vi vuxit till experter på klassisk membranvattentätning och nyare integrerade, dvs. vita tankvattentätninglösningar.
Med den erfarenheten och kunskapen har vi lärt oss att analysera underjordiska strukturer på ett sätt som gör att vi kan komma fram till den mest optimala vattentätningslösningen för strukturen. Utöver det löser vi olika problem relaterade till vattentätning genom att vara på plats varje dag. Vi vet exakt vad som händer på marknaden och hur vi bäst kan hjälpa till.
Med den metoden har vi lyckats samarbeta med generalentreprenörer i hela Baltikum och spara tid och pengar för våra kunder!

Primostar Group AS
As a result of the reorganization, everything bearing the Primostar name will be moved into one AS Primostar Group.
Primostar Group AB We established a subsidiary in Sweden.
What is the story behind the development of Primostar's eco-friendly waterproofing solution?
In the past, we imported construction joint profiles from German manufacturers for many years, but when using them on the construction site, the products developed some defects, which we wanted to improve with our own production. That's how the idea came to create the WPM® brand in 2018, whose main field of activity was waterproofing solutions for construction joints and controlled volume shrinkage cracks in concrete structures.
WPM® - from idea to implementation
We started production with simpler R and L construction profiles, which would be weather-resistant and become homogeneous when solidified with concrete.
In the first half of 2019, we started patenting the Crack Inducing Waterstop profile, and at the end of the year, the profile was used for the first time on the project Valge Street 16, as you can see in the video below.
Primostar's integral, i.e., white tank waterproofing solution, is a comprehensive approach to underground, reinforced concrete structures - using WPM® Metal Sheet waterstop, Crack Inducing waterstops, and crystalline waterproofing concrete admixture.

WPM® Crack Inducing Waterstop
is used to control shrinkage cracks, which results in the planned shrinkage crack being immediately waterproof and in the desired location.
WPM® Metal Sheet Waterstop
used for waterproofing construction joints against pressurized water in various underground, reinforced concrete constructions.
Crystalline waterproofing admixture
gives the concrete a self-healing ability. Together with the water entering the crack, the admixture can close the static cracks in the concrete with an opening width of less than 0.4 mm.

PASSIONATE TO WATERPROOF
BELOW GRADE SMARTER AND GREENER!
SAVE
THE ENVIRONMENT
-
You will use 10X less waterproofing material.
- In order to be environmentally friendly, we have removed the packaging from the products.
SAVE
TIME
-
Compared to conventional waterproofing, the installation of white tank waterproofing is up to 20x faster.
- The solution will last as long as the construction.
SAVE
RESOURCE
-
You save on labor costs because the installation can be done by any concrete worker.
-
Installation does not require additional equipment or special technology.
