Bricks are generally a little more expensive, and will also require a longer installation time, leading to higher labour costs.Ĭoncrete blocks are porous and will absorb water, which can cause issues with outer walls as water penetrates the blocks, before freezing and expanding during cold weather. Cost: Concrete slabs can ultimately be the more cost-effective choice when considering parts and labour.Clay bricks are lighter and also smaller, making them easier to transport and install by hand. Weight: Concrete blocks are heavy, with one block weighing around 20kg.Concrete blocks should offer around 100 years of performance, whereas clay bricks can offer up to 500. In smaller projects, this difference is likely to have minimal impact, but concrete blocks offer superior strength. Strength: Standard concrete blocks are slightly stronger than bricks offering 3500 PSI (a measurement of resistance per square inch) compared to 3000 PSI for clay bricks.By using different aggregates and additives, there are now more options for the look of concrete blocks than before. Concrete blocks are seen as less attractive due to their dull colour and flat appearance, and can often be covered by facades or by a thin wall of bricks to improve their appearance. Appearance: Bricks are generally considered to be a more visually pleasing material than concrete blocks, and are installed as-is for buildings like houses. Here are some of the key comparisons between the two: When looking to build a smaller property within the UK, such as a house, the two main material options for structural work will be concrete blocks or clay bricks.
