Water Holding Structures

The Bai Xi Reservoir spillway had experienced progressive surface deterioration, cracking, and water infiltration due to long-term exposure to flowing water, weathering, and operational stress. Visible cracking—ranging from fine surface cracks to wider structural cracks exceeding 0.2 mm, raised concerns regarding durability, watertightness, and long-term serviceability of the spillway structure.

A drinking water tank with an area of approximately 2,000 m² was successfully waterproofed using XYPEX Concentrate crystalline waterproofing. The goal of this project was to provide long-term protection of the concrete structure against water infiltration, ensuring the tank remained completely safe for contact with drinking water.

The Daejeon Expo Aquarium, located on the first basement floor of the Daejeon Science Complex in Daejeon City, Korea, spans 6,623 square meters and has quickly become a prominent attraction. This new construction features a unique two-floor design, including a 94-meter-long submerged tunnel offering panoramic views of marine life.

The rehabilitation and waterproofing project for the Ikaalisten Vesitorni Water Tower in Finland required materials certified for potable water. Its shape also presented unique challenges making it difficult to install scaffolding and access both the inner and outer basins, so traditional waterproofing methods were not suitable applications.

The objective of the Drahonice Reservoir project was to effectively seal construction joints within a newly constructed concrete water reservoir. Completed in 1994 in Drahonice, Czech Republic, the project encompassed two reservoirs, each with a capacity of 5000 m3. The project used Xypex Concentrate to address the sealing needs. Applying Xypex products effectively provided a comprehensive seal at construction joints, permanently preventing leaks.
