The construction industry continues to be a hotbed of patent innovation. Activity is driven by an increased focus on environmental sustainability and workplace safety, and the growing importance of technologies such as the Internet of Things (IoT) and robotics. In the last three years alone, there have been over 27,000 patents filed and granted in the construction industry, according to GlobalData’s report on Innovation in construction: self-healing concrete.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.
Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.
80+ innovations will shape the construction industry
According to GlobalData’s Technology Foresights, which plots the S-curve for the construction industry using innovation intensity models built on over 240,000 patents, there are 80+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, waterproof floor drains, adjustable width road pavers and construction 3D printing are disruptive technologies that are in the early stages of application and should be tracked closely. Floating breakwaters, self-healing concrete and building panel interlocking are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are pneumatic door closers and embossed floor panels, which are now well established in the industry.
Innovation S-curve for the construction industry
Self-healing concrete is a key innovation area in construction
Self-healing concrete, also known as self-repairing concrete, refers to a type of concrete endowed with the capability to autonomously repair cracks and damage. This unique characteristic is achieved through diverse mechanisms. One method involves incorporating microcapsules filled with healing agents such as epoxy resins or sodium silicate, which are released and harden upon crack formation, restoring the concrete's integrity. Another approach utilizes bacteria embedded in the concrete mix that remain dormant until a crack appears. Upon activation by water entering the crack, these bacteria produce calcite, a form of calcium carbonate, filling the crack and restoring the structure. Additionally, self-healing concrete may employ shape memory polymers that, when exposed to specific stimuli such as heat or light, contract and pull cracks closed. This innovation represents a transformative leap in construction materials, enhancing durability and minimizing the need for external repairs due to environmental stressors or regular wear and tear.
GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 105 companies, spanning technology vendors, established construction companies, and up-and-coming start-ups engaged in the development and application of self-healing concrete.
Key players in self-healing concrete – a disruptive innovation in the construction industry
‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

Schlumberger takes the lead in total patents filed for self-healing concrete, followed by Gebr Knauf and BASF.
Headquartered in Houston, Texas, US, Schlumberger is a leading multinational technology company that specializes in providing comprehensive solutions to the oil and gas industry. Established in 1926 by brothers Conrad and Marcel Schlumberger, the company has grown into a global powerhouse known for its innovative technologies and services in reservoir characterization, production, drilling, and processing.
Schlumberger is at the forefront of industry advancements and is committed to sustainability and social responsibility. The company plays a key role in the development of the new energy transition, aligning its operations with emerging technologies and environmentally conscious practices.
In the context of recent developments, Schlumberger has also demonstrated interest and involvement in cutting-edge materials and construction technologies. For example, the company recognizes the significance of self-healing concrete, a revolutionary type of concrete that possesses the ability to repair cracks caused by wear, tear, or environmental factors. This aligns with Schlumberger's commitment to innovation and its contribution to sustainable practices in various sectors, including construction and infrastructure development.
In terms of application diversity, Geopolymer Solutions, KONE, Atlantis Holding, and Air Liquide are some of the leading companies in the space.
By means of geographic reach, Nichiha held the top position, followed by Calera and CEA.
Air Liquide is a leading supplier of industrial gases, specializing in the production of essential gases such as oxygen, nitrogen, hydrogen, argon, and rare gases. The company serves diverse industries, including steel, food, pharmaceuticals, chemicals, electronics, automotive, and manufacturing. In addition to supplying gases, Air Liquide is involved in designing and constructing processing facilities and related infrastructure.
In March 2023, Air Liquide showcased its commitment to innovation by submitting a patent application for a method and equipment designed to condition wet concrete. This involves agitating wet concrete in a revolving-drum concrete mixer, bringing changing portions of the wet concrete to a free surface inside the mixer. The agitated wet concrete is cooled and partially carbonated through the simultaneous supply of liquid and/or solid carbon dioxide and liquid nitrogen to the concrete mixer, ensuring that both gases contact the free surface of the wet concrete. This patent application reflects Air Liquide's dedication to advancing technology in the concrete industry and self-healing concrete products.
