Pavers are the most reliable material for building a walkway or a driveway or installing an outdoor kitchen. Believe it or not, correctly built pavers are structurally stronger than concrete and can handle significantly more weight and wear than blacktop.
Pavers instantly drain water into the ground, making them less muddy in rainy weather and dusty in dry weather. Furthermore, pavers are flexible and will not crack in the same manner that concrete does. However, there is one main reason why pavers fail: they lack a robust paver base.
A solid paver patio, walkway, or driveway requires the use of correct base materials and an installation strategy. Paver bases offer a sophisticated touch to any outdoor home improvement project. When the right materials are used, paver foundations are efficient, quick to build, and easy to install. A paver base consists of three levels: subgrade, subbase, and base. Each layer provides a certain form of support and has a distinct material composition. Subgrade refers to the lowest layer of compacted dirt beneath the installation site. The word "sub-base" refers to the intermediate support layer that rests on top of subgrade soil.
