Grain Silos

Behira, Smouha & Bani Mazar, Elmenya, Egypt

To waterproof and safeguard new grain silos in Behira, Smouha, and Bani Mazar, Elmenya, contractors applied Xypex Admix C 1000 NF to the horizontal slabs and used Xypex Concentrate for wall repairs. This approach was specifically designed to shield the structures from up to 8 meters of hydrostatic pressure, thereby enhancing their durability and waterproofing capabilities. The use of Xypex products in this project markedly increased the concrete's durability and the silos' overall longevity, ensuring they remain resilient against environmental pressures.

Biogas Plant Anaerobic Digestors

Mramorak, Serbia

The Mramorak biogas plant in Serbia, operational since December 2019, represents a pivotal advancement in renewable energy technologies, specifically in converting organic waste into biogas. This project underscores the importance of selecting construction materials that can withstand the harsh conditions of anaerobic digestion—a process where microorganisms decompose organic matter without oxygen, producing biogas but also creating a highly corrosive environment for conventional concrete.

Projects Using This Product

General Construction Foundation

Setia Spice Convention Centre

Malaysia

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

China
General Construction Foundation

Gateway Arch Expansion

USA

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

Brazil

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

Singapore

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

USA

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.

Bridges

Zuidhorn Rail Bridge

Netherlands

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.
