The \"white tank\" technology is one of the most popular waterproofing methods in Poland, yet it often suffers from a poor reputation. Why is this?<\/p>\n
In Poland, there is no clear, unified definition for the term. Originating from Germany, the \"white tank\" concept has seen significant technological advances in concrete properties over the years. However, outdated guidelines from decades ago are still commonly used. On the Polish construction market, the white tank approach is often tailored individually by contractors based on their methods rather than standardized procedures. Importantly, \"white tank\" is not a regulatory term but rather a technological vision created by suppliers of coating-free waterproofing systems, including accessories for sealing construction joints.<\/p>\n
A \"white tank\" is a type of coating-free waterproofing. It is a monolithic reinforced concrete structure where the concrete itself acts as both the load-bearing component and the waterproofing layer. In Poland, this method typically uses \"water-resistant\" concrete with a W8 rating. However, this rating does not imply complete waterproofing but instead indicates a level of water permeability.<\/p>\n
The construction of a white tank is executed in phases, known as \"pours\" or \"tacts.\" These phases are planned to induce controlled cracking in specified areas of the structure. Furthermore, a maximum allowable crack width is typically set (commonly 0.2 mm for water pressure, as per Eurocode 2 standards).<\/p>\n
While this approach is well-intentioned, its implementation often relies on assumptions and outdated practices, leading to inconsistent results in waterproofing performance.<\/p>\n

The white tank method, particularly with the use of advanced additives like BETOCRETE-C, represents a modern, efficient approach to waterproofing. However, it requires precise execution, appropriate material selection, and adherence to updated guidelines to ensure long-term reliability. By addressing the shortcomings of outdated practices, this technology offers robust protection for critical structures such as foundations, basements, and water storage tanks.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
The negative reputation of the \"white tank\" technology in Poland often stems from a lack of comprehensive knowledge among those responsible for its design and implementation. While this is not a universal issue, it frequently leads to the repetition of outdated solutions, which in turn results in complications during later stages of construction. Designers are well-versed in building structures; however, for many, the \"white tank\" simply represents concrete with a specific strength class. Practically speaking, they focus on the structural calculations and include safety factors. If the foundation interacts with water, they specify \"water-resistant\" concrete (W8) and consider the technology complete.<\/p>\n
It is important to clarify that W8 concrete is not fully waterproof. Additionally, the Polish standard PN-B-06265 no longer includes water-tightness grades. New projects should avoid referencing the \"W\" parameter, as it is no longer recognized in updated standards. Instead, the focus has shifted to measuring water penetration depth under hydrostatic pressure. This represents a significant change:<\/p>\n
There is a growing trend toward constructing buildings in more challenging terrains and at deeper levels. This has introduced more complex geotechnical and hydrogeological conditions. For example:<\/p>\n
The \"white tank\" is only as strong as its weakest link. Problems can arise at multiple stages:<\/p>\n
Maintaining strict adherence to technological standards is critical for the success of \"white tank\" construction. Even minor deviations can compromise its watertightness. However, the technology does have one advantage: leaks are relatively easy to locate. For example:<\/p>\n
The \"white tank\" technology offers significant potential when executed correctly but demands precision at every stage of the project. Ensuring proper design, execution, and maintenance is essential to prevent common issues and maximize the benefits of this advanced construction method.<\/p>\n

The Schomburg company offers its globally proven \"White Tank\"<\/em> hydroisolation system using the BETOCRETE-C<\/strong> crystalline admixture. This admixture supports the self-healing process of shrinkage cracks in concrete, ensuring long-term structural integrity and watertightness.<\/p>\n The BETOCRETE-C system simplifies the process of designing and constructing \"White Tanks\" by providing a complete set of standards for project development.<\/p>\n The external side of the foundation is constructed using watertight concrete in the BETOCRETE-C system, with sealed construction joints at plate-wall, wall-wall, and plate-plate interfaces.<\/p>\n One of the key benefits of this solution lies in its compliance with Eurocode<\/strong> standards, which are stricter than Polish norms. Here's the comparison:<\/p>\n This seemingly small difference has a significant impact on the durability and watertightness of the structure. Water entering cracks in a 0.3 mm<\/strong> system serves as a carrier for sulfates, CO\u2082, and chlorides, which can:<\/p>\n The Eurocode 2<\/strong> (specifically, \u201cEurocode 2-- Design of Concrete Structures -- Part 3: Silos and Liquid Retaining Structures,\u201d p. 10) explicitly limits crack widths to 0.2 mm<\/strong> for liquid retaining structures.
