Richlam100 Waterproofing Admixture
Water-Based Self-Healing Integral Waterproofing Additive
Richlam® specializes in biomimetic self-healing concrete technologies. Richlam100 represents a major breakthrough in the commercialization of this technology. This self-healing waterproofing admixture is available in both water-based and powder forms. It is formulated with highly active crystalline growth factors, catalysts, and proprietary additives. Once added to concrete, it promotes deep crystallization and self-healing, helping to prevent early-age cracking and autonomously seal new cracks over time. The result is a highly dense concrete matrix with near-zero permeability, significantly enhanced waterproofing performance, and long-term durability—while greatly reducing maintenance costs.
Richlam100 is a water-based integral waterproofing admixture for concrete, designed for high-efficiency dosing and ease of use. Compared to other crystalline waterproofing agents on the market, Richlam100 achieves optimal performance at a low dosage of just 2 kg/m³. Its pumpable water-based formulation allows it to be added directly at batching plants or even manually into transit mixers, significantly reducing workload for general contractors and concrete suppliers.
To support large-scale applications, Richlam® also offers dedicated automated dosing pumps compatible with Richlam100 for simplified integration.
Biomimetic Self-Healing: Breakthrough Waterproofing Technology
Key Features of Richlam100 Self-Healing Admixture
Richlam®’s biomimetic self-healing concrete technology mimics the way animal bone tissue regenerates after injury. Its core lies in the synergy between crystalline growth factors and the concrete matrix. These hydrophilic agents actively seek out moisture and water vapor, forming robust crystals in cracks and pores. These interlocking crystals seal cracks, block capillaries, and restore structural integrity—enhancing concrete density and integral waterproofing performance.
Richlam® has achieved global success in synthesizing and catalyzing water-based crystalline growth factors, and is the first to develop a water-based integral self-healing admixture for concrete. With Richlam100, plastic shrinkage cracking can be reduced by up to 80%, and cracks up to 0.4–0.6 mm can be autonomously healed. Waterproofing performance reaches as high as Grade P20 impermeability.

Dormant in Dry, Crystallizing in Water
How Richlam® Builds Integral Waterproofing Structures
The root cause of concrete leakage lies in cracks and capillaries, which serve as pathways for water and harmful agents. Richlam® self-healing waterproofing admixtures are rich in crystalline growth agents that activate upon contact with water. Once activated, they react with the alkaline compounds in concrete to form dense crystals that fill cracks and pores—resulting in self-healing concrete.
Inspired by biological healing mechanisms, Richlam® addresses macro problems with micro-scale innovation. Its crystalline waterproofing admixture mimics periosteum regeneration by precipitating crystals at crack sites, sealing fissures and closing pores. The admixture features a unique cycle of dry-state dormancy and water-triggered crystallization, continuously repeating as needed throughout the life of the concrete. Richlam100 can heal cracks up to 0.6 mm and reduce concrete porosity by 20%, creating a tighter, more water-resistant matrix.
Under an electron microscope, this healing process resembles the regeneration of biological tissue. You can observe crystal growth at crack sites, nanometer-scale pore filling, and a visible increase in concrete density.

Self-Healing Waterproofing: A Global Consensus
Partner with Us to Shape the Future of Waterproofing
Membrane-based waterproofing is only a temporary surface solution. Decades of construction experience confirm that the future of waterproofing lies in integral systems embedded within the concrete itself. Yet true self-healing concrete has long been a challenge. Richlam® answers this challenge by shifting the focus—from treating leaks to eliminating cracks at their source.
With Richlam®, waterproofing is not the goal—it’s the result of improved concrete quality. Beyond waterproofing, Richlam®’s biomimetic self-healing technology enhances durability against corrosion, carbonation, freeze-thaw damage, and alkali-aggregate reaction. According to the American Concrete Institute (ACI), crystalline admixtures are among the most effective methods for improving concrete durability and extending service life.
