How to extend a patio


This allows a homeowner to expand her patio and create more space for entertaining friends. After discussing their options, Mark with the homeowner agreed that it was the best decision to leave the patio as is and build onto it.

Mark then shows the homeowner the granite pavers that he intends to use. He also suggests a design that will expand the patio and add a modern touch.

Expansion of an existing patio

  1. Begin by drawing the design on grid paper. You will need to measure each patio paver you bought and plan how to place them alongside your existing patio. The larger pavers can be used for chairs and tables.
  2. Take the distance you want to measure from the patio, and then use the marking paint for the outline of the new patio.
  3. Call the local utility locator before digging to make sure you aren’t disturbing underground utilities.
  4. You can use the excavator for digging in the area marked and removing all topsoil.
  5. To ensure that the area is square, clean up the edges and corners with the shovels.
  6. Spread crusher run on the patio cut-out. Continue to add crusher run until it is approximately 6 inches thick. To compact it, you can either tamp the area or use an electric compressor to compress it. Make sure the base is level.
  7. To represent the thickness of stone dust, lay two identical-sized pipes on top of the crusher ran. Spread the stone dust onto the patio area using the rake. Take care not to damage the pipes. To level the stone dust, lay a 2×4 on both pipes. Fill in any areas that are low.
  8. Lay the patio pavers according to the grid plan that you have drawn on grid paper. To create even gaps between stones, use small pieces of 2x4s. To adjust the alignment of the pavers and to place them in their proper places, tap the mallet.
  9. Cut strips of synthetic grass to fit between patio pavers. Place them with landscaping spikes.
