Cement the edges of the paved area.
Compact bedding sand and pavers to finish the paved area, using a plate compactor.
Cut paving stones to size and for edges, using a splitter and a masonry saw.
Design paver installation layout pattern and create markings for directional references of joints and stringlines.
Discuss the design with the client.
Prepare base for installation by removing unstable or unsuitable materials, compacting and grading the soil, draining or stabilizing weak or saturated soils and taking measures to prevent water penetration and migration of bedding sand.
Resurface an outside area with cobblestones, terracotta tiles, concrete or other materials.
Screed sand level to an even thickness, and recheck sand exposed to elements, raking and rescreeding if necessary.
Set pavers, aligning and spacing them correctly.
Supply and place base materials, edge restraints, bedding sand and jointing sand.
Sweep sand from the surface prior to opening to traffic.
Sweep sand into the joints and compact pavement until the joints are full.
