Bigbloc Construction Limited, incorporated on June 17, 2015, in Gujarat, stands as a leader and innovator in the construction industry. It is one of the largest and the only listed company in the AAC (Aerated Autoclaved Concrete) block space in India.
The company specializes in the manufacturing of AAC blocks, offering an extensive product range that includes fly-ash and sand-based AAC blocks under the brand NXTBLOC, Block Jointing Mortar under the brand NXTFIX, and Ready-Mix Plaster under the brand NXTPLAST. It markets its products under the NXTBLOC, NXTPLAST, NXTFIX, and ZMARTBUILD brand names. Founded in 2010, the company is based in Surat, India.
Bigbloc Construction Ltd is India's largest listed AAC block manufacturer, boasting a combined annual capacity of 1.3 million cubic meters across its plants. These manufacturing facilities are strategically located in Kheda, Umargaon (Vapi), and Kapadvanj (Ahmedabad) in Gujarat, and Wada (Palghar) in Maharashtra.
The company has systematically expanded its manufacturing capabilities. In FY25, Bigbloc Building Elements Pvt Ltd, a wholly-owned subsidiary, completed the Phase 2 expansion of its AAC block manufacturing plant in Wada, Maharashtra. This expansion doubled its capacity from 2.5 lakh to 5 lakh cubic meters per annum, further solidifying BigBloc Constructions Ltd's position as one of India's largest AAC block manufacturers.
Bigbloc Construction Ltd has formed a significant joint venture, SIAM Cement BigBloc Construction Technologies Pvt Ltd, with Thailand's SCG International (BigBloc holding 52% and SCG 48%). This JV has commenced commercial operations at India's first AAC wall plant in Kheda, Gujarat. Built with an investment of Rs. 65 crore, the plant has a 2.5 lakh CBM annual capacity and specializes in producing large-format AAC walls (ranging from 8 to 20 feet long). This venture marks SCG Group's inaugural investment in India.
The JV has already secured a notable order worth Rs. 4.5 crore from Tata Projects Ltd to supply and install 2 lakh sq. ft. of 100 mm AAC panels at Micron India's Sanand facility. This represents its first major order. Furthermore, the company received IIT certification for its new product, "ZMARTBUILD WALL by NXTBLOC," and is currently the sole supplier in India capable of delivering 20-foot AAC wall panels, a product previously reliant on imports.

On September 13, 2024, the Board of BIGBLOC Construction allotted 7,07,87,875 equity shares as bonus shares in a 1:1 ratio. Consequently, the paid-up equity share capital increased to 14,15,75,750 equity shares.
Promoter holding in BIGBLOC Construction Ltd has shown an increase, rising to 72.67% as of March 2025 from 72.42% as of June 2024.
According to Executive Chairman Narayan Saboo, the Q2 FY25 financial performance was primarily impacted by excessive monsoon conditions in Western India, which affected demand, production schedules, supply chains, and operational efficiency. The consolidated capacity utilization of the three running plants was 60%, lower due to the temporary shutdown of the Umargaon, Vapi plant for technology upgradation. Management remains optimistic for strong growth in Q3 and Q4 of FY25, noting that the Umargaon Plant upgradation was completed on October 16, 2024, and operations have since commenced and are being scaled up gradually.
India is the second-largest block manufacturer globally after China, and the AAC market in the country is projected to grow rapidly. Bigbloc Construction continues to focus on expanding its manufacturing capacity and geographic reach to capitalize on the increasing demand for sustainable building materials across India.
