Concrete Surface Protection with Crystalline Technology

When it comes to protecting a concrete surface, integrating a waterproofing system is critical for the durability and performance of the structure. Crystalline waterproofing is a product of ingenuity that has redefined the landscape of concrete protection. Picture an intricate web of crystals, intricately woven within the very fabric of concrete, shielding it from water and other deleterious substances. Xypex Concentrate and Aquafin IC act like the alchemists of the modern construction era, transforming porous concrete into an impenetrable fortress.

The Science Behind Crystalline Waterproofing

Crystalline waterproofing is a revolutionary technology that relies on a unique chemical reaction to create a permanent solution for concrete waterproofing. When Xypex Concentrate or Aquafin IC is applied to a concrete surface, their active chemicals react with the natural by-products of cement hydration such as calcium hydroxide. This reaction forms a new, insoluble crystalline structure that fills the pores, capillaries, and micro-cracks of the concrete. This formation blocks the pathways for water and waterborne contaminants, making the concrete surface impermeable.

Xypex Crystalline Waterproofing: Going Beyond the Surface

What sets Xypex Concentrate apart is its ability to work way beyond the surface. Once applied, it becomes an integral part of the concrete. Even if the coating on the concrete surface is damaged, the Xypex crystalline technology within the concrete continues to function.

Its unique properties allow it to reactivate in the presence of water, leading to further crystalline growth, thereby self-healing non-structural hairline cracks. This makes Xypex Concentrate a sustainable and long-term waterproofing solution, providing an invaluable layer of protection to concrete structures

Xypex Crystalline Technology

Xypex Concentrate leverages Xypex’s crystalline technology to offer integral crystalline waterproofing. When water enters the concrete, it typically seeps through pores and capillaries. However, with Xypex, the active chemicals react with the water and the by-products of cement hydration to form a non-soluble crystalline formation within the pores and capillaries.

Applying Xypex to the Concrete Mix

Xypex Concentrate can be added directly to the concrete mix as a crystalline admixture. This ensures that the crystalline technology becomes an integral part of the concrete structure from the beginning.

Xypex as a Surface Application

Alternatively, Xypex can be applied to existing concrete surfaces as a crystalline slurry. This application technique, called crystalline slurry waterproofing, is highly effective in filling the hairline cracks and preventing water from penetrating the concrete surface.

Long-Term Protection

The crystalline structure formed by Xypex’s crystalline technology remains as an integral part of the concrete, providing long-term protection against water ingress and contaminants.

Aquafin IC and its Crystalline Technology

Like Xypex, Aquafin IC also employs crystalline technology in its waterproofing methods. It can be used as both a crystalline admixture waterproofing or as a crystalline coating waterproof.

Crystalline Admixture

Adding Aquafin IC as a crystalline admixture to the concrete mix ensures that the crystalline formations are uniformly distributed throughout the concrete, making the entire structure waterproof.

Crystalline Coating

Alternatively, Aquafin IC can also be applied as a waterproof coating to the surface of existing concrete structures. This crystalline coating waterproof forms crystals within the pores and capillaries, effectively sealing them.

Crystalline Waterproofing: The Sustainable Choice

Crystalline waterproofing systems provide long-term protection for concrete structures, reducing the need for maintenance and repair. The crystalline technology is an integral part of the concrete structure, enhancing its durability and lifespan. It’s a one-time application, which not only saves time and labor but also contributes to the project’s overall sustainability.

Metro Sealant’s Offerings

Metro Sealant offers both Xypex crystalline waterproofing and Aquafin IC products. They are highly recommended for scenarios where concrete structures are susceptible to water ingress, especially in areas with high hydrostatic pressure.


Concrete structures require a robust waterproofing system to guard against water and contaminants. Crystalline concrete waterproofing, utilizing crystalline technology, is one of the most effective ways to achieve this.

Both Xypex Concentrate and Aquafin IC form an integral crystalline structure within the concrete, which prevents water and contaminants from entering. Whether you’re looking to incorporate the technology into a new build through a crystalline admixture or protect existing concrete with a crystalline slurry or coating, Metro Sealant’s offerings of Xypex and Aquafin IC are premier choices for long-term concrete surface protection.
