More than fifty years ago, demonstrating some brilliant ingenuity, a group of chemists at Xypex Chemical Corporation developed a technology that would change the way concrete is protected from intrusive liquids.

Basic to the development of Xypex Crystalline Technology was a thorough understanding of concrete’s chemical and physical makeup. Concrete is porous. Its tunnel-like capillaries are a natural part of its mass, and permit the passage of water and other liquids. Researchers at Xypex recognized the opportunity for a chemical treatment that would fill these capillaries to prevent the penetration of water and other liquids from any direction. By means of diffusion, the reactive chemicals in Xypex products use water as a migrating medium to enter and travel down the capillaries of the concrete. This process precipitates a chemical reaction between Xypex, moisture and the by-products of cement hydration, forming a new non-soluble crystalline structure. This integral structure fills the capillary tracts rendering the concrete waterproof. Thus came about Xypex concrete waterproofing products.

The fact that Xypex Crystalline Technology is now specified and used on thousands of diverse waterproofing projects around the globe is a testament to the original concept. Crystalline waterproofing technology was an idea that grew because Xypex chemists questioned what concrete was all about and found a way to make it better. Today, we continue the tradition.

When you select Xypex, you’ve chosen the best: more than 40 years of independent testing of our original crystalline technology and still NO EQUAL.

Today, Xypex sets the standard of exacting excellence in its field, and continues to be specified and applied in more and more major concrete applications.

Xypex products are found in most African countries including Egypt, Tunisia, Algeria, Mauritania, Sierra Leone, Ghana, Nigeria, Angola, Namibia, Botswana, South Africa, Zimbabwe, Mozambique, Zambia, Mauritius, Seychelles, Tanzania, Rwanda, Uganda, Kenya, Ethiopia, Djibouti and Eritrea.

Xypex have been involved in African infrastructure projects for many years. As investment and opportunities in Africa grow Xypex has seen larger infrastructure projects take place throughout the continent.

Xypex products are designed to be an integral part of a concrete structure and ultimately extend the service life of new and old concrete structures, whether it is for example a basement structure, bridge or water treatment plant.
