Richlam® Biomimetic Self-Healing Waterproofing
Pioneering the Future of Self-Healing Concrete Technology
Richlam® is a global pioneer in biomimetic self-healing concrete technology. As one of the first to commercialize intelligent concrete systems, Richlam® has led the advancement of self-healing concrete waterproofing—a transformative innovation in the shift toward integral waterproofing solutions for modern infrastructure.
Inspired by the regenerative mechanisms of animal bone tissue, Richlam®’s technology uses crystalline growth factors to mimic biological self-repair processes. These crystalline waterproofing agents integrate seamlessly with concrete to actively seal cracks, prevent leakage, and provide long-term protection. With its self-sensing and self-repairing properties, self-healing concrete not only becomes its own waterproof barrier, but also redefines structural durability in the construction industry.
Richlam® believes that biomimetic intelligent concrete will become the new standard for future buildings. We are committed to developing smart materials that can sense, respond, and adapt—pushing the boundaries of what concrete can achieve. To date, Richlam® has achieved significant breakthroughs in self-diagnosing cracks, temperature regulation, and crack healing, as well as in the synthesis and application of crystalline concrete waterproofing admixtures. These innovations drastically reduce repair costs and deliver exceptional economic and social value.
Crystallization Waterproofing: A Smart System
The Science Behind Richlam® Integral Waterproofing
Richlam®’s crystalline waterproofing technology simulates the healing process of the periosteum in animal bones. When embedded in concrete, its crystalline admixture lies dormant until activated by moisture. Upon water ingress, these self-healing concrete waterproofing chemicals form dense crystals within cracks and capillaries—sealing them permanently.
This integral crystalline waterproofing cycle of dormancy–activation–crystallization–dormancy repeats automatically for the life of the structure. Richlam®-protected structures can self-heal cracks up to 1.0 mm, eliminating the need for external maintenance and delivering true maintenance-free concrete waterproofing.
At the core of Richlam®’s waterproofing system is its highly active crystalline admixture for concrete, engineered for deep penetration, rapid crystallization, hydrophilicity, and alkali activation. Whether added integrally or applied topically, these crystalline waterproofing admixtures transform concrete into a self-regulating and self-repairing waterproof system.

Smart Materials, Smarter Infrastructure
Biomimetic Technology for the Age of Intelligent Concrete
Smart materials are those that can sense environmental conditions and respond intelligently. Richlam®’s biomimetic concrete introduces these capabilities to traditional building materials, creating systems with self-diagnosing, self-tuning, self-recovering, and self-repairing functionality.
In the world of concrete, self-healing technology is the entry point to intelligent systems and represents the highest standard in concrete durability. Its importance is comparable to that of lithography in the semiconductor industry. Richlam®’s self-healing concrete waterproofing is not just a product—it’s a new generation of construction materials that actively improve their own performance over time.
Two Key Approaches to Biomimetic Concrete:
1. Capsule/Fiber Tube + Adhesive Method
Mimics blood clotting by embedding capsules or fiber tubes filled with healing agents. When cracks occur, capsules rupture to release adhesives that bond the crack. However, this method has limited commercial scalability due to its complexity and single-use nature.
2. Crystalline Growth Factor Method
Mimics periosteum bone regeneration. Crystalline waterproofing admixtures embedded in concrete respond to water ingress by forming healing crystals at crack sites. This method is the first to achieve real-world commercial application in self-healing concrete.
Self-Healing in Action
Cracks, Capillaries, and Defects—Sealed from Within
Richlam®’s crystalline concrete waterproofing technology goes beyond cracks. It also heals voids, honeycombs, surface blemishes, and micro-defects. Among these, capillary pores are the most common and dangerous, acting as channels for water and chemical ingress. Richlam®’s crystalline waterproofing agents penetrate into nanoscopic pores, crystallize in place, and significantly reduce porosity—enhancing the density and durability of the structure.
Under electron microscopy, the effect is visible: nano-pores blocked, voids sealed, and the matrix densified. This is self-healing concrete, backed by science, designed for the future.

Integral Waterproofing: A Global Shift in Mindset
Work with Richlam® to Build Smarter, Stronger Concrete
Membranes address symptoms, not root causes. Richlam® challenges this outdated model by focusing on the source of leakage—cracks and defects in the concrete itself. Waterproofing should not be an afterthought—it should be the result of better concrete.
Through crystalline waterproofing admixtures, Richlam® enhances structural durability and resolves common quality issues like cracking, corrosion, carbonation, freeze-thaw deterioration, and alkali–aggregate reactions. The American Concrete Institute (ACI) has identified crystalline self-healing technology as one of the most effective ways to enhance concrete performance.
Richlam® is redefining waterproofing as an inherent property of high-performance concrete.
