For this reason, we recommend packing your gravel base in layers. Plate compactors can generally compact 3-4″ at a time. The more compressed your base is, the less it will shift and settle over time, keeping your pavers level and in place for longer. Both products allow for adequate compaction and drainage-compact your gravel base with a vibrating plate compactor. This can be either 3/4″ crushed stone or a 3/4″ recycled concrete product. We suggest using 3/4″ gravel for the base. Doing so will work as a barrier to stabilize the base and stop the clay from mixing with your added base material. If you are in an area that is mostly clay or have other poorly draining soils, we recommend placing a layer of geotextile fabric down over the compacted sub-base. When excavation is complete you will compact the sub-base with a plate compactor or hand tamper. The deeper the base is mined the more gravel you can add for increased support and stability. Clay soils should be excavated deeper than sandy/loam areas. If the project is for a driveway, or an area that will hold vehicular traffic, excavate 8-12″. If the pavers are for only pedestrian traffic, dig 6″ below the finished grade. You’ll want to extend the markings by 6″ on all sides to ensure enough room for your gravel foundation and paver edge restraints.Įxcavate the area to 6-12″ below the finished grade, depending on the use of pavers and the soil conditions. Use spray marking paint to outline the projected work site clearly.
Once all utilities are marked, you can layout your project. Skipping this step could result in severe damage and injury, as well as fines from your local municipalities and utility companies.
You will want to make sure you notify DIG SAFE before any excavation, so all underground utilities are marked.
