The Thomas Armstrong Hollow Dense Concrete Block is the perfect solution for constructing robust and durable walls that require reduced weight without compromising on strength.

Ideal for both above and below damp-proof course applications, these blocks seamlessly integrate into agricultural, commercial, and industrial projects, such as sheds, storage bunkers, ponds, and retaining walls. Constructed from high-quality class 2 aggregates with a significant proportion of recycled materials, these blocks not only support sustainable building practices but also comply with BS EN 771-3 standards. The hollow cores can be filled with concrete and reinforced with steel, ensuring exceptional strength and resistance to lateral loads. The Standard texture finish block provides an excellent base for mortars, renders, and plasters, making them versatile for various construction finishes. With ISO 9001 and ISO 14001 certifications, alongside BES 6001 Responsible Sourcing certification, these blocks are both environmentally friendly and responsibly sourced. Additionally, at the end of their lifecycle, the blocks are 100% recyclable.
