Kilsaran Hollow Cavity Blocks are reliable building components for construction projects. Designed for structural efficiency and insulation, these blocks offer versatility in various applications. Their precise dimensions and high-quality construction make them ideal for creating sturdy and energy-efficient walls in both residential and commercial buildings. Concrete blocks are composed of Portland cement and aggregate, with high-density blocks potentially using sand and gravel, and low-density blocks using industrial waste instead of aggregate. The blocks have a dimension of 215mm x 215mm x 440mm, also known as cavity blocks.
