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 232,000 patents, there are 80+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, self-healing concrete, waterproof floor drains, and construction 3D printing are disruptive technologies that are in the early stages of application and should be tracked closely. Smart glazing, regeneration control hydraulics, and floating breakwaters are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are wall surface temperature controls and embossed floor panels, which are now well established in the industry.

Innovation S-curve for the construction industry

Drainage flow regulators is a key innovation area in construction

Drainage flow regulators refer to devices or structures designed to control or regulate the flow of water in drainage systems, such as in stormwater management systems or wastewater treatment systems. These regulators ensure that the flow of water is controlled, preventing flooding and erosion, while also preventing the buildup of sediment in the drainage system.

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 280+ companies, spanning technology vendors, established construction companies, and up-and-coming start-ups engaged in the development and application of drainage flow regulators.

CRH’s subsidiary Hydro International, a manufacturer and provider of water management products, services and expertise, is a leading patent filer in drainage flow regulators. A key innovation by the company is the development of a vortex flow control device used for regulating the flow of water in drainage systems. The device induces turbulence in the region of the inlet to control the flow of water. Other innovations by the company include a stormwater gully designed to prevent flooding during high rates of flow in stormwater systems. The gully features bypass inlets that allow for the rapid discharge of water if water levels rise too high. China Construction First Building Group, a provider of engineering services and a subsidiary of China State Construction Engineering (CSCEC), is another key patent filer in this space. One of its innovations includes the development of a water-draining residue soil collecting pit used in drainage systems that contains water collecting holes and joints to pump water from the pit. This reduces the water content in residue soil, improving transportation, and disposal.

In terms of application diversity, leading innovators in the space include Rockwool International, Totetsu Manufacturing, and Kadant. By means of geographic reach, Orbia Advance held the top position, followed by Xylem and Nippon Koei.
