Bricklayers typically specialize in laying bricks and blocks to construct walls, buildings, and other structures. While some bricklayers may also have experience in laying pavers, paving work is generally considered a separate trade that involves laying and finishing surfaces with materials such as concrete, asphalt, or interlocking pavers. Therefore, while there may be some overlap in skills, bricklayers and pavers are typically distinct professions with their own areas of expertise. **

Concrete paving stone works refer to the use of concrete pavers to create durable and visually appealing surfaces for outdoor areas such as driveways, walkways, patios, and pool decks. These pavers are made from concrete and come in a variety of shapes, sizes, and colors, allowing for endless design possibilities. The installation of concrete paving stone works involves laying the pavers in a pattern on a prepared base, which provides a stable and long-lasting surface that can withstand heavy foot traffic and vehicle loads. This type of paving is popular for its versatility, low maintenance, and ability to enhance the aesthetic appeal of outdoor spaces. **

Paving stones should be stored on a flat, stable surface to prevent them from shifting or cracking. They should be stacked in a way that distributes the weight evenly and prevents them from leaning or tilting. It's important to keep them covered with a tarp or plastic sheeting to protect them from moisture and dirt. Additionally, it's best to store them in a location that is easily accessible for when they are needed for installation. **

Paving brick 1b quality refers to a type of brick that is considered to have minor imperfections or irregularities that do not affect its overall functionality or durability. These imperfections may include slight variations in color, size, or texture. Paving brick 1b quality is still suitable for use in landscaping and construction projects, but it is typically sold at a lower price compared to higher quality bricks. **

Under the paving stones, you will typically find a base layer of compacted gravel or crushed stone, which provides a stable foundation for the pavement. This base layer helps to distribute the weight of the pavement and prevent it from shifting or sinking. In some cases, there may also be a layer of sand or geotextile fabric to further support the pavement and prevent weed growth. Overall, the materials under the paving stones are carefully chosen to ensure the longevity and stability of the paved surface. **

The cost of paving works can vary depending on various factors such as the size of the area to be paved, the type of material used, and the complexity of the project.
