Using WoodBlocX kerbing kits is easy and fun to build. The pieces are light enough to carry and you don't need special tools to put it together. Don't use old railway sleepers! They are no cheaper, much harder to work with and will break your back. WoodBlocX is more attractive and will last longer. WoodBlocX timber is specially selected pine from sustainably managed forests. It is quarter-sawn avoiding the centre of the tree and pressure treated twice during the manufacturing process which will give you over 20 years of use - all approved organic by the soil association. All our kits include all the capping you need for your design. Need a different size? Use our calculator to find the components and price of any size of walling with standard BlocX sizes.
