Richlam® Concrete Admixture
Self-Healing Technology for Integral Concrete Waterproofing
Richlam® is the integral waterproofing brand under Richlam Development Group LLC, specializing in crystalline waterproofing systems for concrete. The product line includes concrete crystalline waterproofing admixtures, surface-applied crystalline waterproofing sealer and coatings, and crystalline admixtures for mortars, available in both liquid and powder forms. These products are applied either integrally or topically, forming a comprehensive waterproofing solution for concrete structures. All Richlam® products are engineered to promote self-healing of concrete cracks, ensuring that “no cracks mean no leaks.” This creates truly self-healing concrete, with waterproofing performance that lasts the entire life of the structure.
Richlam® is a global pioneer in biomimetic self-healing concrete technology, advancing the commercial use of smart materials that mimic natural self-repair mechanisms. Richlam®’s self-healing waterproofing admixture is formulated with highly active crystalline growth factors, catalysts, and proprietary agents. When added to concrete, it produces dense, low-permeability concrete that resists cracking and heals itself automatically. These crystalline waterproofing admixtures react with water and free lime to seal hairline cracks and block water pathways, significantly enhancing durability while reducing long-term maintenance costs.
Biomimetic Innovation:
The Crystalline Technology Behind Richlam®
Inspired by the regenerative capabilities of living organisms, Richlam® mimics the way bone tissue heals after trauma. The core of Richlam®’s crystalline waterproofing technology lies in its highly reactive nano-silica-based crystalline growth factors. Activated by moisture and the high alkalinity of concrete, these agents deeply penetrate the structure, form robust crystals, and effectively block water ingress at the capillary level. This is the essence of concrete crystalline waterproofing—a science-based approach to integral concrete protection.
Research from the Richlam® Technical Center shows that the internal alkalinity of concrete can be up to 360 times higher than the surface. Richlam®’s deep-penetrating crystalline admixture for concrete fully utilizes this alkalinity to activate crystal growth deep within the matrix, continuously seeking water and moisture. This results in the formation of dense, interlocking crystals that self-heal cracks, seal capillaries, and drastically improve the impermeability of both concrete and mortar.

Self-Diagnosis, Self-Repair
Self-healing Waterproofing for Smart Concrete
Richlam® is dedicated to developing biomimetic smart concrete technologies that sense, adapt, and repair themselves. Today, Richlam® has made significant strides in the areas of crack detection, thermal regulation, and crack self-control, advancing from concept to commercial success. The ultimate goal: concrete that behaves like a living organism—capable of healing itself and extending its own service life.
At the heart of this innovation is Richlam®’s crystalline self-healing technology, which simulates biological cell regeneration. These active ingredients automatically detect and repair both micro and macro defects in concrete, resulting in durable, maintenance-free structures. With Richlam®, even hairline cracks no longer require external repair.
How Richlam® Self-Healing Waterproofing Works:
-
Penetration: Richlam® crystalline admixtures are added integrally or applied to concrete surfaces, penetrating capillaries and micro-cracks. In the absence of water, they remain dormant.
-
Activation: When cracks form and water enters, the hydrophilic crystalline agents are activated by the high alkalinity and react with cement hydration byproducts to form crystals that seal cracks up to 0.6 mm.
-
Breathability: Once sealed, the path for water ingress is blocked, while vapor can still escape. This keeps the internal environment dry and prevents moisture accumulation.
-
Reactivation: In the absence of water, the system returns to a dormant state. Upon future cracking or leakage, the cycle restarts, forming new crystals and sealing the crack.
-
Repeatability: The self-healing process repeats continuously throughout the structure’s lifespan, maintaining protection against future damage.

Self-Healing Waterproofing: A Global Consensus
Partner with Us to Shape the Future of Waterproofing
Membrane-based waterproofing is only a surface solution, not a structural one. Industry experience shows that the future lies in integral waterproofing systems embedded in the concrete itself. Yet achieving true self-healing concrete has long been considered an engineering challenge. Richlam® provides the answer through a revolutionary shift in perspective: Instead of treating leaks, eliminate the cracks.
At Richlam®, waterproofing is not the end goal—it is the natural result of improving concrete quality through crystalline self-healing technology. Richlam® not only solves waterproofing issues but also significantly enhances durability by preventing corrosion, carbonation, freeze-thaw damage, and alkali-aggregate reaction. According to the American Concrete Institute (ACI), crystalline waterproofing admixtures are among the most effective methods for increasing concrete durability today.
