Turf or grass pavers are void pavers used for the construction of holey pavements. They are set up using concrete grids or soil enhancement technologies as the base. Grass turf pavers start on with a grid-like formation, sometimes referred to as a 'honeycomb' system. Once this grid is set up, topsoil, sand and gravel are added inside the grid. This helps to prevent the turf or grass from settling and collapsing from beneath itself, whilst still encouraging filtration.
