Cob is a mixture of clayey soil, straw and water. These 3, simple ingredients are mixed together to create a medium that has been identified globally as an effective and efficient building material. Clayey soil must contain aggregates, such as gravels and sands Barley straw is commonly used as a binder when making cob Here…
Whether it’s a cob wall rebuild, an extensive cob repair or a cob new build, cob blocks are the go-to product. By using pre-formed cob products such as cob blocks, the builder/s can be assured [that once in situ] they can accommodate plasters and renders very soon afterwards. Here at Earth Blocks Ltd in Cornwall…
Here at Earth Blocks Ltd, we’re always pushing the boundaries. We experiment with, and test new concepts frequently. Our latest Research and Development journey led us to the idea of manufacturing larger dimension cob blocks. Typically, the go-to cob block size is a standard 100mm unit. These products are laid flat and provide an effective…
Here at Earth Blocks Ltd we have quite a varied range of cob products. We manufacture and supply the staple fare for cob walling in our 100mm cob blocks and 125mm cob blocks. In addition to these products, we also manufacture and supply 70mm cob blocks. Where can these 70mm cob blocks be used? We…
Building with cob (and buildings of cob construction) still has its sceptics and one of the most common misconceptions of cob walling is ‘it’s built from mud, so it can’t possibly be strong enough’. Typically, this type of comment has come about from first-hand witnessing of cob walling in a state of failure. Cob…
CRADLE-TO-GATE INFORMATION (per product) RAW MATERIAL (Source) Our raw materials (ie clayey soils) are sourced from large scale development sites and therefore have already been excavated. CO2e figures omitted. RAW MATERIAL TRANSPORTATION (to our facility) Our raw materials (clayey soils) are loaded from stockpile to heavy transport at source and delivered to our…
Our 100mm cob blocks are manufactured from 100% natural and sustainable materials that are sourced locally. So, what does one of our cob blocks consist of? Well, the most important ingredient is clay. Sub-soils that contain clay (particularly here in Cornwall) are common-place and this remains the principal reason why there is an abundance of…

Wall thickness = 350mm (excluding plasters and renders) Traditionally we can find cob walling to have no cavity and that they were/are predominantly constructed as solid walling. Monolithic cob walls boast significant thicknesses (usually 600mm) and its these dimensions that compound cob as an effective, efficient and structurally competent building medium. In addition to…
Bonding techniques for our cob blocks and cob bricks is not that different to conventional brick or block laying. There are no specialist skills required to install these cob products, a good general builder or a competent DIY’er can achieve a good construction. Methodology relies on an effective lap ensuring vertical jointing is staggered. Here…
