The Zemseal® system has passed all tests with the highest possible water pressure and has therefore been classified in the highest performance category.

Zemseal® – Top Performance Rating 💧💧💧

Construction Type Regulation by "Deutscher Beton Verein" (DBV)

The "German Concrete Association" (Deutscher Beton Verein) has published a guideline titled “Sub-structure waterproofing systems”, which provides a regulatory framework for this type of construction. This significantly improves the safety of use on construction sites. In addition, the guideline defines a “General Proof of Applicability.”
📌Regulation of sub-structure waterproofing systems according to the DBV guideline.

Deutscher Beton- und Bautechnik-Verein

German Concrete and Construction Technology Association Proof of Applicability (aA)

The defined performance criteria must be verified by an authorized testing body. The system undergoes 22 mandatory tests as well as optional performance evaluations. Classification is based on three performance levels.
📌The performance levels depend on the tested water pressure.

Why is this certification important for you as a customer?

The general proof of applicability increases the safety and reliability of use for all parties involved in the construction process, enabling efficient and dependable system application.
📌A fundamental requirement for watertight concrete construction concepts.

The following tests were performed:

  • Basic test
  • Resistance to impact loading
  • Flexural behavior
  • Tear resistance and elogation at break
  • Resistance to penetration
  • Watertightness and resistance to water tracking
  • Coefficent of friction
