Richlam500 Waterproofing Admixture
Self-Healing Waterproofing Additive for Mortar
Richlam500 is a specialized mortar waterproofing additive with self-healing capabilities, designed to address cracking and leakage problems in cement-based mortars. Developed with Richlam®’s biomimetic self-healing technology, the product integrates highly reactive crystalline growth factors that inhibit early-age shrinkage cracks and seal microcracks that form later. This crystalline waterproofing admixture for mortar enables reliable, cost-effective performance even at low dosages—making it ideal for use in large-scale construction mortar systems.
Formulated from advanced crystalline waterproofing agents, catalysts, and proprietary additives, Richlam 500 mimics the regenerative mechanisms of bone tissue. Upon activation by water, its hydrophilic crystalline admixture for mortar forms dense crystals in cracks and capillaries, sealing voids and restoring watertightness. This transforms the mortar itself into an integral waterproofing layer—ensuring “no cracks, no leaks.”

Visible Results with Self-Healing Mortar
Watch Richlam® in Action
Mortar-based waterproofing is widely used in roofing, exterior walls, kitchens, bathrooms, floors, basements, and water tanks. Yet traditional waterproofing mortars often suffer from inconsistent quality, high cracking rates, and poor long-term reliability. In many regions, external walls have long lacked adequate waterproofing layers, while basements rely on membranes that deteriorate over time. These have become the most common sources of structural water ingress.
To address this issue, new international standards increasingly mandate the use of waterproofing mortar in exterior walls. The challenge is achieving high-performance results while maintaining cost-efficiency. Richlam500 offers a breakthrough: a concentrated mortar waterproofing chemical that reacts with cementitious alkalinity to form deep-set crystals, filling voids and self-healing cracks up to 0.4 mm. In real-world projects,

Self-Healing Technology for Mortar
The Science of Crystalline Mortar Waterproofing
Water ingress in mortar remains a widespread issue, rooted in two main causes: microcracks and high porosity. The Richlam® solution combines early crack control and post-crack healing to prevent leakage at the source. Richlam500 applies integral crystalline waterproofing principles, forming crystals directly within the mortar structure to block water pathways.
Richlam®’s crystalline waterproofing admixture is based on smart materials that switch between dormant and active states depending on moisture levels. When water is present, crystalline growth factors are reactivated to seal new cracks and voids. This dormancy-activation-crystallization cycle continues throughout the life of the structure, ensuring self-healing mortar that requires minimal maintenance.
