Concrete Blocks

Concrete blocks are a reliable, cost-effective choice for strong, long-lasting construction. Ideal for load-bearing walls, partitions and general building work, our range is built to support everything from small extensions to larger structural projects – with options to suit different strength requirements and build specifications. In this category you’ll find popular sizes and strengths, including 100mm and 140mm concrete blocks for a wide range of wall builds. Choose lightweight concrete blocks (100mm and 140mm) when you want easier handling on site and improved workability, or opt for higher-strength options like 140mm Concrete Block 7N, 100mm Concrete Block 7.3N, and 100mm Concrete Block 10.4N where structural performance and compressive strength are key. Whether you’re building foundations, forming internal walls, or upgrading a structural element, our concrete blocks help you work faster and build with confidence.
