Paving stones are a very valuable material used in the construction industry. This is mainly due to the good properties of the ankle joint and the wide possibilities of its use. Thanks to this material, many different surfaces can be finished. Cobblestones are used, in particular, for the construction of sidewalks, garden alleys or driveways. How are the cubes arranged on the ascents?Determination of the nature of the foundation and paving surface
Before we move on to laying paving stones, we first need to determine how we intend to use it. The type of cube used and the thickness of the technological layers under it depend on it. Of course, these parameters are also affected by the type of substrate. When we do not have detailed information about the soil, it is worth taking geodetic measurements. Next, it is necessary to determine the loads that will be applied to the surface of the paving stones. The greater the weight acting on the pavement, the thicker not only the cube should be, but, above all, the layers under it. I'm talking mainly about the foundation. In a situation where only cars will move along the paving stones, the base layer should be about 40 cm. On the other hand, when heavier cars or cars will drive on the surface, it is better to use a thicker base layer. This is equivalent to a deeper pruning.Preparation of the site for paving stones
Laying paving stones begins with pruning. This stage consists in choosing the humus or topsoil on which the paving slabs will be laid. As mentioned earlier, the depth of the channel depends mainly on the type of foundation and the bearing capacity of the pavement. Already when pruning, a slope of 2-3% should be taken into account so that water does not accumulate on the surface. This stage ends with the leveling of the base and compaction of the trench. The next step is to create a border. Then it's time to make a base layer. The bearing capacity and stability of the entire surface depends on it. The foundation is made of aggregate or small crushed stone. In the case of garage entrances, its thickness should be about 35 – 50 cm. Note that this layer is done in stages. After laying the first few centimeters of the foundation, seal it and proceed to laying the next layer. Repeat this operation to achieve the aforementioned thickness. The last element of the preparation of the foundation for paving stones is ballast. Its main task is to align previously laid layers. The litter is usually made of fine washed sand or fine crumbs.The last stage, i.e. paving stones laying
When the substrate is properly prepared, you can proceed to the arrangement of cubes. Paving works start from the extreme corner of the frame, and then move from the outer edge to the center, so they do not spoil the ballast. It is important that the cubes are not placed next to each other. Always observe small distances between individual cubes, which will then be covered with sand. This action will allow the road surface to work freely. If the cubes were placed next to each other, they could damage each other. The last step is to seal the surface and align the cracks in the grout. https://estrelabet-brazil.com/
