Thakeham Building Blocks All-Purpose Dense and Medium Dense Aggregate Concrete Blocks

Thakeham Calxite Dense Aggregate Concrete Blocks Manufactured to BS EN 771-3 Built to Last. Unrivalled Versatility. Dense aggregate blocks create durable and long-lasting constructions and are the most widely used and versatile building block available today. They offer a cost-effective and proven building method, allow effective control of noise and heat, and permit the range of strengths required for most designs and applications. Thakeham’s Calxite range of dense aggregate blocks is Close Textured as standard and is available in a number of sizes and configurations. These smooth faced...

Thakeham Teklite Medium Dense Aggregate Concrete Blocks Manufactured to BS EN 771-3 Improved Insulation. Easier Handling. Thakeham Teklite blocks are manufactured using lightweight aggregate which permits the construction of walls with high levels of thermal insulation whilst retaining good sound absorption characteristics. In conjunction with cavity wall insulation, U-Values as low at 0.20 W/m2K can be achieved. In addition, being lighter than a dense block, handling is easier enabling increased site productivity. Our Teklite range of blocks is available in a General Purpose finish. 25%...

Key Advantages of using Aggregate Building Blocks (ABB) Cost Effective ABB allow a quick and cost effective method of construction that has been the traditional form of building proven over centuries. The versatility of the product can reduce costs in the simplification of the construction process and on site regulatory compliance. ABB’s high strength means they are well suited to be used in potentially high loadbearing applications and are both robust and durable, meaning constructions are both long lasting and secure. The longevity of ABB constructions can help to maximise retention of...
