Grey Block 290mm

For heavier-duty blockwork and engineered walls, Grey Block 290mm provides a strong, stable concrete Besser® block option with a wider profile — ideal for applications where you need extra mass, core-fill capacity and reinforcement space. This range is commonly specified for retaining walls (engineered), structural walls, boundary walls and commercial projects where performance and durability matter.

BuildMart’s 290mm range includes practical shapes for cleaner detailing on site — including H blocks (single web) for reinforcement layouts, end blocks for neat wall terminations, and half blocks (closed ends) to reduce cutting and deliver a more consistent finish.
