Richlam200 Self-Healing Waterproofing Admixture
Powder Form Integral Concrete Waterproofing Additive
Richlam® specializes in biomimetic self-healing concrete technology, and its self-healing waterproofing admixtures represent a key milestone in the commercialization of this innovation. These products are available in both water-based and powder forms, formulated with highly active crystalline growth factors, catalysts, and proprietary additives. Once added to concrete, they enable crystallization and self-healing, preventing early-age cracking and autonomously sealing micro-cracks—forming a dense, low-permeability matrix. The result is self-healing concrete with enhanced durability and long-term waterproofing performance, while reducing costly repairs.
Richlam200 is a powder-form crystalline waterproofing admixture and a classic solution widely used in China, classified under cementitious crystalline waterproofing agents. Compared to similar products on the market, Richlam200 requires a lower dosage of only 3 kg/m³. Its efficiency and ease of use make it suitable for both batching plants and manual addition into transit mixers, simplifying the process and making it a preferred choice among contractors and concrete producers.
Biomimetic Self-Healing: Breakthrough Waterproofing Technology
Key Features of Richlam200 Crystalline Admixture
Richlam®’s biomimetic self-healing concrete technology is inspired by the regenerative mechanisms of bone tissue. By incorporating crystalline growth factors into the concrete matrix, the system actively tracks water ingress and responds by forming robust crystals within cracks and pores. These crystals seal pathways, enhance concrete density, and restore the structure’s waterproofing ability from within.
As a pioneer in crystalline waterproofing admixture technology, Richlam® maintains an industry-leading position. Richlam200 is globally recognized for its high activity and superior crack-healing performance. It can autonomously heal cracks ranging from 0.6 to 1.0 mm, enabling a truly integral waterproofing system where “no cracks mean no leaks.”

Dormant in Dry, Crystallizing in Water
How Richlam200 Builds Self-Healing Concrete Structures
Concrete leakage originates from cracks and capillary pores—primary channels for water and chemical attack. Richlam® self-healing admixtures are rich in active crystalline agents that react with moisture and the alkaline compounds in concrete. Upon activation, these agents generate crystalline structures that fill and seal cracks and defects, turning ordinary concrete into self-sealing, crystalline concrete waterproofing.
Through biomimicry and material science, Richlam® replicates the natural healing process of bone regeneration. The admixture’s dry-state dormancy and water-triggered crystallization allow it to reactivate repeatedly throughout the concrete’s lifespan. With Richlam200, cracks of 0.6–1.0 mm can be fully healed, and porosity can be reduced by up to 20%, significantly enhancing impermeability and structural integrity.
Under an electron microscope, crystal formations can be seen growing across the crack surface, mimicking organic tissue regeneration. Nano-scale capillary pores are sealed, and the surrounding matrix becomes visibly denser and more water-resistant.

Self-Healing Waterproofing: A Global Consensus
Partner with Us to Shape the Future of Waterproofing
Membrane-based solutions address symptoms, not causes. Long-term field experience confirms that true waterproofing begins with the concrete itself. However, achieving structural self-waterproofing has long challenged engineers, due to the unpredictable nature of cracks and internal defects. Richlam® answers this challenge by shifting the perspective—from surface treatment to internal performance enhancement.
Waterproofing is not the end goal—it is the natural result of stronger, more durable concrete. Richlam®’s biomimetic self-healing technology not only solves waterproofing issues, but also significantly boosts performance against corrosion, freeze-thaw damage, carbonation, and alkali-aggregate reactions. As the American Concrete Institute (ACI) states, crystalline admixtures for concrete are among the most effective technologies for improving durability and protecting concrete for its full design life.
