Lightweight Aggregate Blocks and Dense Concrete Blocks

At Thomas Armstrong (Concrete Blocks) Ltd, we manufacture a comprehensive range of lightweight and dense concrete blocks including different textures and sizes across each block type. This range features lightweight aggregate blocks, dense concrete blocks as well as coursing bricks, concrete commons, slip blocks and T-beam infill blocks for block and beam flooring applications.

Our Lightweight Aggregate Blocks are designed to help reduce heavy lifting and carrying by minimizing the weight of the concrete blocks, whereas our dense concrete blocks are highly resilient, tough, loadbearing blocks suitable for any background or internal fair-faced application. They are also available in Solid, Cellular and Hollow forms.

The quality of our products is important to us, so our concrete blocks are designed to the highest quality to meet your commercial and residential building needs. They are manufactured to BS EN 771-3 and are ISO 9001 Quality Assured, ISO 14001 Environmentally Certified and hold BES 6001 ‘Excellent'.
