Hollow Dense Concrete Block 7.3N

The Hollow Dense Concrete Block 7.3N is a strong masonry unit made with dense aggregate concrete. It has hollow cores that reduce weight while still providing reliable structural performance. The block has a smooth grey finish and consistent shape, making it easy to lay and suitable for fast progress on site.

Its dense composition provides good acoustic mass and inherent fire resistance, making it suitable for internal and external walls in homes and commercial buildings. The block also offers thermal mass benefits, supporting more stable indoor temperatures. Its moisture-resistant structure and long-term durability make it suitable for foundations, load-bearing walls, infill panels and general masonry work where strength and reduced weight are important.

Installation Guide:

• Prepare a level and stable base for laying
• Apply a full bed of mortar across each course
• Position blocks with accurate alignment and level checks
• Maintain consistent joint thickness during the build
• Cut blocks using suitable masonry tools if needed
• Allow mortar to cure before applying finishes or loading
