## Short description
Isokristall is a WTA-certified waterproofing system for retrospective interior waterproofing of basements, masonry and floor slabs. According to the website, the system does not merely block out moisture. Instead, it actively uses the existing moisture: active ingredients penetrate deeply into walls and floor slabs via the concentration gradient, bind the water and convert it into a mineral masonry structure. This is presented as turning the building structure itself into a watertight "white tank".

## Main value proposition
- Retrospective waterproofing from the inside without excavation, digging or drilling
- WTA-certified for soil moisture and seepage water
- WTA-certified for pressurized water
- Watertight up to 1.5 bar
- 100% radon-tight according to the website, certified by IAF Dresden
- Horizontal and vertical barrier in one system
- Optional warranty of up to 30 years

## Technical principle
The website describes Isokristall as a recrystallization process. The active ingredients use the moisture already present in the structure, penetrate deeply into mineral masonry and strengthen it. The goal is not just a superficial barrier layer, but a lasting mineral transformation inside the component itself. This is described as effective both for rising damp and for high water pressure.

## System structure
The website describes a 5-layer or 8-layer system, depending on the usage class. It specifically mentions:
- primer
- crystalline slurry
- fine filler
- protective coating
- finish coating

For interior basement waterproofing, the process is described as:
1. Free structural analysis and on-site consultation with a non-binding quotation
2. Application of the first three layers
3. Drying period
4. Further protective coatings plus optional bonding bridge and final plaster or tiles
5. Acceptance and warranty certificate

## Target groups and problems
The website addresses property owners, builders, renovation customers and prospects with issues such as:
- damp basements
- wet walls
- leaking floor slabs
- pressurized water
- rising damp
- mold and musty odors
- radon exposure in basements and buildings

## Application areas
The website names the following examples:
- basements
- floor slabs
- underground garages
- elevator pits
- tunnels
- listed or otherwise sensitive existing buildings

## History and proof
The website presents the history in the following way:
- Recrystallization processes for waterproofing have been used in North America for more than five decades.
- According to the website, around 19 years ago a German process was developed that permanently seals not only concrete but also various mineral masonry types.
- According to the website, the Isokristall system was developed in Germany in 2020 and 2021 exclusively for the building protection network of 1a-Gebaeudeabdichtung GmbH.
- According to the website, product testing under WTA quality standards took place at MFPA Leipzig between July 2024 and January 2025.
- According to the website, all Isokristall components received the WTA certificate in May 2025.

## Radon protection
Radon protection is a major focus of the site:
- Isokristall is presented as 100% radon-tight.
- The proof cited is a certification or test by IAF Dresden.
- The website points out that radon is one of the most frequent causes of lung cancer after smoking.

## Comparison with conventional methods
The website positions Isokristall against classic waterproofing methods by emphasizing:
- no excavation and no drilling
- no purely artificial barrier layer
- active use of existing moisture for waterproofing
- WTA certification in both categories
- radon protection
- suitability for pressurized water up to 1.5 bar
- long-term active ingredients
