19 August 2026 – American start-up Dmat is developing concrete that can seal small cracks by itself. The technology is based on MIT research into the remarkable durability of ancient Roman concrete, some examples of which have survived for nearly two thousand years.
Researchers led by Admir Masic discovered that calcium-rich particles play an important role in Roman concrete. When water enters a crack, calcium-containing compounds can dissolve and subsequently recrystallise. The resulting minerals can partially or completely fill the opening.
Dmat applies this principle through additives for modern concrete and repair mortars. According to the company, the technology could extend the service life of concrete structures by approximately 50 percent while substantially reducing carbon emissions. The actual environmental benefits depend on factors including the concrete mixture and its service life.
The materials are already being used in infrastructure projects in Italy and Switzerland. The approach could reduce maintenance requirements and the consumption of new construction materials.
