MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611023980 A) filed by Swami Vivekanand Subharti University, Meerut, Uttar Pradesh, on Feb. 27, for 'a thermo-responsive zoned soil expansion control grid and method for mitigating swelling in expansive soils.'
Inventor(s) include Aanchal Sharma; Daud Chauhan; Ibran Khan; and Soni Dubey.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a thermo-responsive soil expansion control grid (TR-SECG) for mitigating swelling and shrinkage behavior in expansive soils. The TR-SECG comprises a geogrid or geotextile matrix embedded within an expansive soil layer and integrated with phase change material (PCM) microcapsules. The PCM microcapsules are distributed in spatially variable concentrations to form thermally responsive zones aligned with structural load concentration regions beneath civil structures. During elevated temperature conditions, the PCM undergoes a reversible phase transition that absorbs latent heat, thereby limiting peak soil temperature and reducing thermally induced swelling pressure. The phase transition further induces a reversible modulation of stiffness at a grid-soil interface, enabling dissipation of swelling-induced strain. Upon cooling, solidification of the PCM restores interface stiffness and soil confinement."
