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.
Biomimetic Self-Healing Technology
The Power Behind Richlam300 Waterproof Sealer
Richlam® is globally recognized for its industry-leading innovations in crystalline waterproofing and self-healing concrete. Compared to similar waterproof concrete sealers and spray-applied crystalline coatings, Richlam300 is formulated with high-activity nano crystalline growth factors, allowing for superior penetration and deeper, denser crystalline waterproofing at the surface layer—up to 30 mm in depth.

Spray and Seal — It’s That Simple
A Proven Concrete Protector
Widely Used Waterproofing Barrier in the U.S. Market
Originally developed by the U.S. Army for moisture protection in military bunkers, Richlam®’s waterproofing spray technology has since become one of the most widely used concrete waterproofing chemicals in the U.S. Known for its performance in waterproofing, moisture-blocking, and dust-proofing, Richlam300 is now trusted in public and commercial applications including roads, bridges, ports, dams, and other critical infrastructure.
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.

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.
