Cairo Metro Line 3 Phase 3 & 4

Cairo, Egypt

In the Cairo Metro Underground project, specifically for Line 3, Phase 4, Vinci served as both contractor and consultant, facing considerable challenges, particularly with the initial waterproofing material. To address these issues, the project team opted for Xypex Concentrate, a move that significantly improved the waterproofing of stations and water tanks within the project. A total of 12 tons of Xypex Concentrate was utilized, demonstrating its effectiveness in a demanding environment.

Valore Antoniades Compound

Alexandria, Egypt

The Valore Antioniades project, located in Alexandria, Egypt and developed by Valore Real Estate Investment Company, used Xypex products for waterproofing against high hydrostatic pressure of up to 4 meters. Spanning around 22,000 square meters, the development includes seven blocks and 20 residential towers.

Spolar Power Plants - Transformer stations, Fire water tanks

Accros the Country, Hungary

In Hungary, as in other countries around the world, the harnessing of solar energy for direct energy production is increasingly becoming popular. Recent years have seen the construction of several small and notably more powerful solar power plants. These solar parks aim to further decrease Hungary's reliance on fossil fuels and reduce the emissions of harmful substances.

Somfa Liget, Residential Building, Phase VII

Budapest, Hungary

The seventh phase of the Somfa Liget residential park was completed in the newly developed area of the X. district of the capital, adjacent to the earlier phases, within a peaceful and serene environment. 

Dagály Park, Residential Building, Phase 2

Budapest, Hungary

Dagály Park, a multi-phase development by OTP Ingatlan is located just a street away from the Danube. Given its proximity to the river, waterproofing was paramount. The choice of Xypex, renowned for its durable and reliable waterproofing solutions, ensures the development's resilience against high hydrostatic pressure and potential chemical attacks  (dissolved salts and fuel derivatives) from urban runoff.

Application of Xypex Coating Products

Xypex Concentrate is applied as a cementitious slurry to the surface of existing above or below-grade structures to waterproof and protect the concrete against high hydrostatic pressure and aggressive environments.


Projects Using This Product

General Construction Foundation

Setia Spice Convention Centre


Given the environmental circumstances of the location, including a high water table, elevated levels of chlorides, sulphates and carbonating gasses, Xypex waterproofing technology was selected and specified for this project because, unlike other concrete waterproofing systems, Xypex offered permanent and enduring concrete waterproofing and protection, with cost savings accruing from reduced initial construction time as well as future concrete maintenance costs.

Wastewater Collection & Treatment

Bailonggang Wastewater Treatment Plant

Gateway Arch Expansion


The gleaming stainless steel Gateway Arch is the centerpiece of the Gateway Arch National Park and a popular attraction. A plan was developed to dramatically expand and redesign the landscaping and facilities around the base of the Gateway Arch. Waterproofing of all renovated spaces and new facilities was a critical concern.

Dams & Irrigation

Canal do Sertão - Hinterland Water Channel


Xypex Crystalline Technology was introduced to the project as a means to solve a specific problem in the early stages of construction. As a result of its performance it became an important component of the whole project to solve the waterproofing challenges. The combined efforts of the federal government, the design team and the contractors together with technical assistance from Xypex distributor MC Bauchemie, enabled the timely delivery of these stages of this highly important project for the Sertão Nordestino region of Brazil.

General Construction Foundation

National Centre of Infectious Diseases


Xypex’s crystalline system for concrete waterproofing and durability was proposed, approved, and accepted to provide protection to the four levels of underground substructure (basement base slabs and perimeters) and three underground pedestrian/vehicular underpass links.

Water Holding Structures

Picayune Strand Restoration Project


The three pumping stations—Merritt, Faka Union, and Miller—were completed in early 2018 and are being used to restore the flow of freshwater over land (known as sheet flow) and maintain pre-existing flood protection. Soon after completion, hydrostatic pressure caused the Merritt pump rooms, located 20 feet (6 m) below grade, to fill with water.


Zuidhorn Rail Bridge


The use of Xypex Concentrate to protect the new railway bridge over the Van Starkenborgh Canal not only helped keep the project on schedule, but provided a significant cost savings over the epoxy coating that ProRail normally uses on such projects.
