Porcelain pavers can be laid directly over existing grass or lawn as ‘stepping stones’ or to create a pathway, but for better stability of the pavers, the grass beneath the pavers should first be removed, together with a shallow layer of the topsoil. Here's how to install pavers over grass for best results.
Lay the pavers on the grass to determine the number of steps or ‘stones’ needed for the pathway, making sure the pavers are placed at equal distance from each other.
The joint width between the pavers should be chosen depending on the appearance required. For stepping stones or pathways, the pavers would normally be laid with open joints with grass in between. However for areas where outdoor furniture will be used, pavers would normally be laid with closed joints.
Mark the perimeter of each paver with a spade and then remove the pavers.
Remove the turf up to a depth of 2”-3”.
Fill with a layer of fine 3/16”-1/4” gravel and compact the gravel before laying the pavers. If preferred, lay a 1” thick layer of sand to add as a bed for the pavers.
Carefully lay the pavers so they protrude above ground level by about ¼”. The pavers must not protrude above the lawn level, to avoid damaging lawnmower blades.
Carefully tap the pavers with a rubber mallet to ensure they are bedded properly.
