With its durability and versatility, cobblestone blocks make the perfect building material to create a distinctive look. Having a smooth curved appearance, cobblestone blocks require very little maintenance and provide a more rustic finish.
For a high quality finish and long-lasting performance, you need to ensure that the laying is done correctly. With a good plan and understanding of the basic features of the cobblestone blocks, you can be successful in your project. Listed below are some tips that will ensure that your cobblestones are well-laid.
To begin with, it is essential to bear in mind that cobblestone blocks vary slightly in size as they are hand-crafted. This is done intentionally and helps to achieve a unique look.
It is a good idea to run the string line on the inner side of the wall than on the outer side. This will help to ensure that the inside wall better accommodates the cornice, skirting or rendering. This method will also give the outer wall a little more character.
Blocks that have a flatter face and are without curves are ideal for the top and bottom courses, as well as for door and window openings. This will enable you to maintain a flat inner surface.
Specialty blocks include the ones with grooves, slots and cut-outs. These blocks must be used only in areas where needed. The use of such blocks in general laying must be avoided as you may run short of the blocks when required.
Cobblestone blocks have a smooth top and rough bottom. This results from the manufacturing method employed. While laying the blocks, make sure that the smooth surface faces upwards. This offers a flat surface for the spirit level and string line.
As cobblestone blocks are handcrafted, the length, width and height may vary. The variation enables to achieve the unique cobblestone look. The bricklayer needs to appreciate that the variation is intentional and accordingly compensate it with the differing thickness of mortar joints. Besides, the cobblestone blocks may also include ‘split faces’,’ poch marks’ and many other similar irregularities. They constitute features that are purposely crafted during the production process.
The colour of the Ligna Stone blocks and bricks may also vary slightly from batch to batch. This is especially true if there is a gap of several months between consecutive orders. To avoid such difference in colour, try to order the entire batch together. In case this is not feasible, you can keep aside a few blocks from the previous batch and blend it with the new batch.
With the knowledge, skill and understanding of laying cobblestone blocks, you can achieve exceptional outcomes. While laying the blocks, it is also important to remember that the Ligna Stone bricks require a full mortar bed in both the vertical and horizontal joints. This is essential for the following two reasons:
The method ensures that the maximum bond and load bearing strength is maintained.
It also prevents the formation of cavities in which water can collect and leak.
Also the longer the block, the greater the cobblestone slump (lower height) and more mortar will be required.
