Patch’n Plug
Xypex Patch’n Plug is a specially designed, fast-setting hydraulic cement compound for concrete patching and repair. It stops flowing water in seconds and is used to seal cracks, tie holes, and other defects in concrete. The high performance characteristics of Patch’n Plug are enhanced by Xypex’s unique Crystalline Waterproofing Technology.

General Resources

Daejeon Expo Aquarium
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.

Manure Holding Tanks
This project involved the application of Xypex crystalline waterproofing across 60,000 sq ft of concrete manure holding tanks in Clovis, New Mexico, for Vanguard Ag, a developer specializing in agricultural waste-to-energy systems. The tanks support anaerobic digestion, a process that breaks down farm and food waste to produce renewable biogas and agricultural byproducts.

Réservoir d'eau potable Saint-Jean - Trois-Rivières
The City of Trois-Rivières awarded Construction Deric a major contract to renovate part of its drinking water network facilities in the west sector, totalling just over $77 million. The 70-year-old reservoir showed signs of hairline cracks and joint seepage. A crucial part of renovating the Saint-Jean reservoir was addressing the concrete degradation and the cracks that had developed over decades of use.

Renovation of the Belvédère Swimming Pool
The Belvédère Municipal Swimming Pool in Tunis, Tunisia, underwent a significant renovation in 2024, blending modern infrastructure improvements with the preservation of a historic landmark. Owned by the Tunis Municipality and supervised by the General Directorate of Military Engineering, the project brought together an expert engineering team comprising consulting engineers Mr. Fredj and Mr. Adel Maatouk, Bicotec Ingénierie under the leadership of Rachid Nouri, and BIAT & Veritas Tunisia.

Las Esclusas Wastewater Treatment Plant (PTAR)
The Las Esclusas Wastewater Treatment Plant (Las Esclusas PTAR) in the southern area of Guayaquil, Ecuador, is part of the "Project for the Universalization of Sanitary Sewerage." It was designed to improve the region's wastewater management, serving over 1 million residents. This facility, completed on October 7, 2022, reflects a shift toward more effective and sustainable construction methodologies.
Projects Using This Product

The Rihand Dam
Being one of the oldest dams in India, the concrete of the dam body has experienced deterioration due to ageing and AAR (Alkali Aggregate Reaction) resulting in cracking and surface loss. Xypex’s unique crystalline technology was chosen as the preferred repair solution due to its cementitious nature and compatibility with concrete along with other technical reasons.

Sydney Harbour Tunnel
Commencing in September of 1991, repair systems using Xypex Concentrate and Patch’n Plug were used as part of an ongoing program of repair and maintenance of the North and South land driven tunnels and transition tunnels of this renown structure.

AASS Wastewater Treatment Plant
The walls of this plant were cast using the Machihembrado method. Because of this approach, Xypex Dry-Pac and Xypex Patch’n Plug were required to seal the construction joints. The same Xypex treatment was used on 518 m of cold joints and cracks. After these structural defects were repaired, the surfaces were treated with a two-coat application of Xypex Concentrate.

Canóvanas Filtration Plant
The thickening tank (92 ft. diameter by 15 ft. deep) of this filtration plant used Xypex Patch’n Plug to repair structural defects followed by a coating of Xypex Concentrate. Upon review, the Xypex treatment proved to be very successful, rendering the tank impenetrable by water.

Chehe River Mine
Xypex products were chosen to rehabilitate these pipes as they resist hydrostatic pressure, chemical attack and are a permanent solution thus avoiding future maintenance intervals and shutdowns. Additionally, they are used on wet concrete so removing the need to dry out the concrete before application. Xypex Patch’n Plug was used to seal active leaks in the pipe joints.

Fiat India Automobiles Private Ltd.
More than 13,000 lbs of Xypex Concentrate and 1,000 lbs of Xypex Patch’n Plug were used to waterproof a surface area of 60,000 sq.ft. Xypex was chosen for its additional benefit of chemical resistance and concrete durability enhancement.

Wastewater Tunnel Repair
The first phase of the project required the Bawax applicator to fill in all of the joints between the precast culvert sections with Xypex Patch’n Plug fast-setting hydraulic cement compound. Patch’n Plug stops flowing water in seconds and is used to seal cracks and other holes or defects.
