The disclosure provides stakeholders with insight into the firm’s governance structures, environmental impact mitigation strategies, and social responsibility initiatives during the period ending March 31, 2026.

The filing reveals that Bigbloc Construction reported a turnover of ₹88,49,92,000 and a net worth of ₹48,01,15,000 for the financial year. Corporate Social Responsibility (CSR) obligations under Section 135 of the Companies Act, 2013 were not applicable to the entity for this period. The company operates primarily through the manufacturing of Autoclaved Aerated Concrete (AAC) blocks, which accounted for 95% of its total turnover. Operations are concentrated nationally across five states, with one plant and one office location.

Operational and Financial Overview

Bigbloc Construction maintains a focused product portfolio centered on sustainable building materials. The primary revenue driver remains AAC blocks, categorized under NIC Code 23954. The company serves a diverse customer base including builders, civil contractors, industries, dealers, and government contractors. There were no export contributions to the total turnover during the reported period.

The entity’s subsidiary structure includes Starbigbloc Building Material Limited (85% stake, held till April 28, 2026), Bigbloc Building Elements Private Limited (100% stake), and a joint venture with Siam Cement Big Bloc Construction Technologies Private Limited (52% stake).

Environmental and Sustainability Initiatives

The report emphasizes significant environmental safeguards, particularly in water management and energy usage. Bigbloc Construction states that its plants operate on a zero-liquid discharge basis, with all surplus water reused in the slurry process, ensuring no external water discharge. This approach aligns with Principle 6 of the National Guidelines on Responsible Business Conduct (NGRBC), focusing on protecting and restoring the environment.

Energy efficiency measures include solar installations at various plants. The company completed a 450 kilowatt solar installation at the Umargam plant and is installing a 625 kilowatt solar plant at the Wada unit. Additionally, the company received an eligibility certificate for subsidy and applied for carbon credit registration at VERRA for the Wada plant. The use of fly ash as a key raw material further reduces environmental waste by repurposing landfill-bound materials.

Governance and Employee Welfare

Governance oversight is managed by Mr. Naresh Sitaram Saboo, Managing Director, with dedicated committees for Corporate Social Responsibility and Risk Management. The Board reviews NGRBC compliance annually. The company reports no instances of human rights violations, non-compliances with environmental or labor laws, or fines imposed by regulatory authorities during the year.

Employee welfare metrics show 143 permanent employees, comprising 134 males and 9 females. All permanent employees are covered by accident insurance, with maternity benefits provided to female employees and paternity benefits to male employees. Cost incurred on well-being measures stood at 0.30% of total revenue in FY26, down from 0.35% in the previous year. The company maintains a grievance mechanism accessible via online portals and physical suggestion boxes, ensuring timely resolution within defined timelines.
