How deep should a paver patio base be?

The base of the paving stone is made of gravel which creates a solid base for the project and helps the area to drain properly. The cobblestone base for a patio or walkway should be 6 inches deep when compacted. You're here because you have a paver project coming up and you want to know how deep you need to dig in order for it to stand the test of time. The short answer is that your paver project will only last as long as your base is deep.

That's why you'll have to dig 7 to 13 below the final slope, depending on the type of traffic you expect the pavers to receive. Use a garden rake to help extend the base material of the paver to a depth of 4 inches across the entire work area. Compact the area until you have a firm base. For a walkway, for example, the thickness of the paver is 3 to 3 ½ inches, you'll need to dig a 9-inch patio base and then fill 5 inches of the hole with the base material, such as sand or gravel.

JS Brick is a company that specializes in the supply and installation of pavers, whatever you need, we support you. Once the trench is filled with sand and gravel and has been compacted, you must place restraints on the base to prevent the base and pavers from moving due to age or weather conditions. After deciding to add pavers, it's normal to have questions about the installation process, from the cost of all labor and materials to the depth at which the pavers must be excavated. One of the most common problems people encounter with their cobblestones is not getting a deep, well-constructed base first.

If you are going to install pavers over a patio or an old concrete base, you won't need to dig at all. The base for these applications must be excavated at least seven inches below the final slope level to ensure a solid foundation for your pavers. If you don't know exactly how much you need to dig to install the pavers, you can leave 4 inches for the gravel and 3 inches for the sand and add them to the depth of the pavers (which is normally 6 inches, but the value may vary depending on the material chosen). To ensure the durability of your paving stone project, the planning and design process must be well thought out.

The depth of the base of the cobblestone is determined by the type of stones used and the type of sand or gravel that will be placed beneath them. It can be made from a variety of materials, but is usually composed of a mixture of ¼ -10 crushed gravel or washed concrete sand that will hold the pavers in place. While a DIY cobblestone patio costs about 50% less than hiring a professional contractor, it's not guaranteed to last and a lot can go wrong in the process. Fill the trench until there is approximately 3.5 inches (8.89 cm) space for sand and pavers.
