Below are guidelines to installing Porphyry Pavers using a sand set method. The preparation of the foundation is the most important element in the success of the installation. The foundation forms the strength and durability of the Porphyry Pavers application.
Porphyry Natural Stone Paver Installation
1. To maintain a solid sand set installation, a soldier course is recommended.
A soldier course is a solid frame or edging which holds the pavers in firmly. It can be in the form of an existing wall, or a cement or stone frame.
2. The foundation is then laid within the frame, or soldier course. The foundation consists of 6-8 inches of crushed stone base material, which is compacted firmly using a plate compactor. The next layer of the foundation is the sand bed, which consists of 2-3 inches of course sand. At the top there should be enough depth to cater for the pavers.
3. Porphyry Pavers are available in the form of tiles or cubes for paving. They come in varying lengths and thicknesses. The thicker the Porphyry Pavers, the more heavy duty they become. So if you’re using them for your patio, the thinnest cubes will be suitable.
4. Set your grading levels at approximately ¼”drop per foot, using string. The string also helps with the alignment of the pavers.
5. Start to place Pavers in the sand bedding, tapping them in firmly. Check for the alignment and level constantly. Remove any uneven pavers, adding or removing sand, and replacing the pavers, to achieve the correct level. With natural stone, screeding is not necessary.
6. It is now time for the joints to be filled. You can sweep sand over the surface, filling the joints. Or you may perhaps use a dry mortar set, consisting of a dry mix of cement and sand, which is also swept over the surface.
7. Use a plate compactor to set the porphyry pavers into the sand firmly.
8. If you chose to use a dry mortar set, then soak the joints with water.
9. Finally, clean the area of excess grout and sand, and sponge over the pavers for extra a clean surface.
