Duo™ Interlocking block range

Our Duo™ blocks are the UK’s fastest and best selling interlocking block solution. They come in three sizes – three, two and one connector – the standard block is a BL2 1200mm x 600mm x 450mm (highlighted in the table below) and weighs 750 kgs.Speed of construction is the key feature – two men can expect to install 228 blocks per day which is over 123m2. The blocks interlock with each other using easy ‘lego’ type connectors and are dry-laid making them a reusable semi-permanent option. Capping pieces are also available to give a great looking finish.A standard articulated lorry can carry 38 of the 1200mm blocks although we are very happy to deliver any number including single blocks.Please click on link below for details of sizes.
