MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202531130157 A) filed by Narula Institute Of Technology, Kolkata, West Bengal, on Dec. 22, 2025, for 'mortar-free interlocking concrete block system for wall construction.'
Inventor(s) include Arya Banerjee; Subhankar Dey; Anasuya Mondal; and Suraj Kumar.
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 details a modular wall construction system utilizing a series of specialized concrete blocks (B1, C1, B2, B3, B4, B5) engineered for mortar-free dry-stack assembly. Each block is characterized by precision-calibrated grooves, recesses, and corresponding projections configured to achieve robust positive mechanical interlocking in both horizontal and vertical directions. This inherent mechanical constraint effectively eliminates the potential for slippage, separation, and misalignment of juxtaposed units under applied loads, guaranteeing the necessary structural integrity. A key feature is the specialized Corner Block (C1), which establishes stable, self-aligned orthogonal wall junctions without requiring any adhesive bonding agent. The system significantly accelerates construction timelines, reduces material consumption and waste, and provides the distinct advantage of complete disassembly and reusability, making it an advanced, efficient, and sustainable solution for modern construction requirements, including low-cost housing and modular buildings."
