Hollow blocks, also known as concrete masonry units (CMUs), are precast cement blocks with one or more hollow cores. Widely used in modern construction, these blocks offer high strength, better thermal insulation, and faster construction compared to traditional bricks. They are ideal for both load-bearing and non-load-bearing walls in residential, commercial, and industrial projects.
Manufactured using a precise mix of cement, sand, and aggregates, hollow blocks reduce the overall weight of the structure while maintaining excellent durability. Available in various sizes, these blocks ensure uniformity, cost-effectiveness, and minimal mortar usage.
