Preprufe Waterproofing System for Foundations from Saint-Gobain Yapı Kimyasalları

The PREPRUFE® waterproofing system, developed by GCP, Saint-Gobain's expert brand in building chemicals, aims to protect foundations against the adverse effects of water in a wide range of structures, from residential buildings to public buildings and industrial facilities. The system, with its "Zero Lateral Water Migration" technology, prevents water from advancing between the concrete and the waterproofing layer.

For structures to be long-lasting and safe, it is necessary not only to use the right applications in the superstructure but also to implement correct engineering solutions starting from the foundation stage. Factors such as groundwater and moisture, in particular, can negatively affect the durability and performance of a structure over time, especially in foundation and basement sections.

GCP, Saint-Gobain's expert brand in building chemicals, offers a solution aimed at limiting the advance of water within the structure in foundation waterproofing with the PREPRUFE® waterproofing system, developed based on more than 50 years of global experience.

The system, which can be used in large-scale applications such as residential projects, public buildings and industrial facilities, aims to create continuous waterproofing at the foundation level with its structure that integrates with concrete.

One of the major problems encountered in foundation waterproofing is that water passes behind the membrane over time and advances between the concrete and the waterproofing layer. This situation can cause water to spread over a wider area within the structure from the point where the waterproofing is damaged.

Advanced Bond Technology, used in the PREPRUFE® system, ensures that the waterproofing membrane integrates strongly with the poured concrete. The technology, which creates an uninterrupted bond between the concrete and the membrane, works to prevent water from advancing between the two layers.

Thanks to the "Zero Lateral Water Migration" feature, the waterproofing layer is designed to move together with the concrete. In this way, a possible leak is prevented from progressing horizontally in the gaps between the concrete and the membrane, reducing the risk of water spreading within the structure.

PREPRUFE® is positioned not merely as a membrane application, but as a holistic system together with different components that complement foundation waterproofing. Supported by complementary products such as special sealing tapes and liquid waterproofing solutions, the system can be adapted to different project needs and site conditions.

Emphasizing that the waterproofing applied at the foundation stage is critical for the structure to maintain its performance throughout its service life, the PREPRUFE® approach focuses on preventing water from advancing within structural elements, facilitating application processes and providing long-term protection.

In this context, PREPRUFE® stands out as an engineering-focused solution in foundation waterproofing, which is not visible but has a direct impact on the durability and service life of the structure.
