When constructing a patio, it is important to first construct your base. In our market, this is usually done with 6” of compacted 2A modified limestone. This base must be installed in “lifts” and properly compacted. It is important to consider the pitch of your patio as well so you can control where your water will flow. Next you screed a level 1” layer of concrete sand and place your pavers on top of this layer. A soldier course is typically used on the outside to accent the patio and then paver edging is spiked in outside of the soldier course. The pavers should be compacted once they are installed and all the proper edging is in place. Finally, polymeric jointing sand should be installed to complete the project.
