Few lawns provide a completely level place for you to install a patio or walkway made out of landscape pavers. Some slope is desirable, because it allows for drainage. You don’t want adjoining pavers to be uneven or they become trip hazards. There are a number of things you can do during installation to ensure that the patio or walkway is level. Careful compaction of the ground and base material is the key to leveling uneven terrain to make a flat surface.
