Brick paving or block paving is used for constructing driveways, patios, pavements, and more. It is commonly used because of its ease of installation, decorative aesthetic, and the fact that they allow easy remedial work by replacing and removing those that are not necessary. The process can be used to achieve various laying patterns, the most being herringbone pattern thanks to the interlocking strength.
You should note that block paving is quite popular when it comes to domestic driveways. In this post, you will learn some different stages that are involved in the given application and other similar applications.
This is the first stage of the paving process. You need to establish the area for block paving. After this, you have excavate the required depth to fit the blocks. Also, you have to ensure it drains away from the building. Usually, a depth of 250mm is ideal. Ensure the ground is excavated to a slope to allow water to run away and not stagnate on the surface. If you have a drainage system installed, then it should be directed towards that. You may need to hire a skip to remove the material you have excavated.
You need edge restraints to frame your block paving. Set up string lines to act as guides to level the kerbs and edge courses. After this, you should lay the kerbs and bricks on a concrete foundation by using a mortar bed and then hammer it gently. You can then install your drainage system and haunch it with concrete for adequate protection.
Laying the Blocks
You should lay the blocks from the corner of the slope. Follow the required measurements. The good thing with a herringbone pattern is that it offers the strongest interlocking bond. When laying the blocks, there is a need to work from the already paved area and not the one that is yet to be paved. After laying all the blocks, you need to check the alignment. Usually, concrete blocks require re-adjustment because of the drifting.
Finishing and Jointing
Jointing requires spreading the dried sand over the surface and sweeping into the joints. You can do this when compacting the paving. There is a need to be careful. Jointing sand can settle after a few weeks, and you can top it up when required. Besides, you can apply a sealant to minimize staining.
