Startup company GreenVibe is applying smart sensors to concrete to evaluate composition by gauging temperature, strength, density and humidity across formulation and pouring. The sensors give construction engineers and project managers data in real time that’s helpful in judging quality and readiness.



The Tel Aviv-based company, founded in 2019, is looking to transform the construction industry by applying smart sensors to building materials — chiefly concrete — to optimize quality and speed up the building process.

Leveraging sensors made in-house, GreenVibe gathers data about concrete composition, feeding back measurements such as temperature, strength, density and humidity during the formulation and pour processes so that on-site construction engineers and development project managers can make better-informed decisions.

The company says its hardware and software system can provide real-time data about the material on construction sites and offer data-driven predictions about quality and readiness.

Concrete is the most widely used building material in the world, and its use is expected to multiply four-fold by 2050 from the existing approximately 30 billion tons used annually. It is cheap, simple to make, and ubiquitous. It is also currently responsible for around 8% of human carbon dioxide emissions because of the ways it is manufactured and used. And cement — its main ingredient — is the most polluting part of the mix.

Yet concrete makes a unique contribution to pretty much everything that is constructed, from tall glassy skyscrapers to bridges and roads, and seems to be in no danger of being replaced. This means the global challenge is to find ways to make the product and its usage more energy efficient and long-lasting.

GreenVibe is not alone in recognizing this. But its solution is gaining ground with leading construction companies because it is simple yet effective.

Concrete is made up of multiple elements, with water, sand, and aggregates bound together with cement, mixed to different recipes for different use cases. Once poured to form part of a structure, the concrete has to be left for a period of time, and tested until it is “ready” for the next stage. Working with concrete requires deep knowledge, time, and some guesswork.
