Richlam300 Self-Healing Concrete Sealer
Water-Based Crystalline Sealer for Concrete Surface Protection
Richlam® specializes in biomimetic self-healing concrete technology, providing high-performance surface-applied waterproofing systems for global infrastructure projects. Richlam300 is a waterproofing spray for concrete, based on waterborne crystalline technology that penetrates the concrete surface and creates an internal sealing layer up to 30mm deep. Its nano-scale crystalline growth factors use water as a carrier to permeate the concrete, react chemically with cementitious materials, and form a dense crystallization waterproofing layer that enhances both waterproofing and corrosion resistance.
As a ready-to-use, water-based waterproofing chemical for concrete, Richlam300 requires no dilution or mixing. It can be directly spray-applied on positive or negative pressure sides of concrete. It is effective even on damp surfaces and does not require special surface preparation. Because it does not interfere with project timelines or require extended curing, Richlam300 has become a preferred penetrating sealer for concrete among general contractors and waterproofing professionals.
Applications include new and existing concrete structures, repair and retrofit projects, waterproofing of water-retaining structures, surface durability enhancement, and microbial/algae inhibition.

Spray and Seal — It’s That Simple
A Proven Concrete Protector
Widely Used Waterproofing Barrier in the U.S. Market
Originally developed for moisture protection in military bunkers, the related waterproofing spray technology has since become one of the most widely used concrete waterproofing chemicals.
Once sprayed onto the concrete surface, Richlam300 penetrates the substrate, forming interlocking crystals that seal from within. Though only applied at the surface, the treatment effectively transforms the concrete itself into a self-sealing waterproof barrier. Unlike surface membranes or coatings, Richlam300 forms no film, does not peel or age, and retains the concrete’s natural appearance. The crystalline waterproofing layer becomes part of the concrete matrix—often described as a “skin-like” waterproofing shield that grows with the concrete.

Global Standards, Global Confidence
Proven Waterproofing for Projects Worldwide
Richlam® focuses on bio-inspired self-healing concrete technologies, delivering dependable waterproofing systems for global clients. With years of research and field applications, we have achieved major technological breakthroughs in the synthesis and performance of crystalline waterproofing admixtures. Richlam® technology offers robust support for resolving the pervasive industry challenges of cracking and leakage, facilitating the realization of truly integral crystalline waterproofing—thereby ensuring that the waterproofing layer endures for the entire service life of the structure.
Richlam® products have earned widespread trust thanks to their exceptional quality and performance. These products comply with relevant standards established by ASTM (USA), CE (EU), UKCA (UK), and GB (China). Richlam® waterproofing chemicals are free of VOCs (Volatile Organic Compounds), are non-toxic and harmless, and meet the requirements of California’s Proposition 65; consequently, they are suitable for use in drinking water and food-grade applications. Furthermore, Richlam®’s product philosophy aligns closely with international green building standards and sustainability goals.

Self-Healing Waterproofing: A Global Consensus
Partner with Us to Shape the Future of Waterproofing
Membrane-based systems offer temporary surface fixes, not structural waterproofing. The industry increasingly recognizes that long-term durability must be built into the concrete itself. Yet true self-healing concrete remains a challenge due to inherent cracking and porosity.
Richlam® offers a new paradigm: enhance the concrete itself with crystalline waterproofing agents that deliver both crack-sealing performance and long-term durability. Our biomimetic technology mimics cellular regeneration to repair cracks, block ingress, and extend the service life of concrete under harsh conditions.
Backed by research from the American Concrete Institute (ACI), crystalline waterproofing chemicals for concrete are now considered among the most effective strategies for protecting concrete infrastructure.
