Measure out the dimensions of your future patio. Place a stake into each corner with a mallet. Stretch string between the stakes to mark the boundaries of the patio. Remove the sod from the top layer of the patio with a sod cutter.
Excavate the patio to a depth of 6 inches with a shovel. Ensure that the ground at the base of the patio is level using a scrap of plywood and a spirit level.
Put a 2-inch layer of crushed gravel into the patio base. Crushed gravel has uneven edges and will interlock as it compacts. Tamp the gravel down using a tamping tool and level the gravel.
Place a 2 inch layer of slightly-damp builder's sand into the gravel. Tamp down on the sand so that it is firm and level. Ensure that the sand is level using a spirit level and plywood scrap.
Place the pavers directly over the sand. Interlock the pavers like a puzzle as you put them in place. For the best results, start at the center of the patio and work your way outward. When you reach the edges of the patio, cut the pavers to fit flush with the sides of the excavated soil and slip them into place.
