Basilisk Self-Healing Concrete is a Delft-based company that develops bio-based concrete products for new construction and for repairing existing structures, including Basilisk Healing Agent, Basilisk Liquid Repair System ER7, and Basilisk Repair Mortar MR3. Its technology uses micro-organisms that produce limestone when exposed to moisture, allowing cracks to seal autonomously and improving durability and waterproofing; the company says cracks up to 1 mm can be repaired. The materials are aimed at concrete users and construction projects that need lower maintenance and reduced CO2 footprint, and the company describes applications in both new and existing concrete structures. The core self-healing technology was invented by Professor Dr. Henk Jonkers and Delft University of Technology, and Basilisk’s site identifies Henk Jonkers as the inventor behind the underlying biobased approach. I did not find a verifiable fundraising round or a clearly stated leadership roster beyond that attribution, so those details are omitted.
