A method of installing paving blocks comprises preparing an area to be paved to a desired grade. A preformed, load-bearing sheet of material, e.g., extruded polystyrene, is placed on the prepared area. Paving blocks are then laid in a desired pattern on the sheet of material.
Claims1
In a method of installing paving blocks comprising the steps of preparing an area to be paved to a desired grade;
- the improvement comprising the steps of:
- providing a sheet of preformed, load-bearing, board-type, foam material having sufficient load-bearing strength for supporting said paving blocks in addition to human and vehicular traffic traversing said paving blocks;
- placing said preformed sheet of foam material directly upon the prepared area and without need of an underlying supporting substructure;
- laying paving blocks in a desired pattern directly upon the preformed sheet of foamed material;
- depositing a joint filling, water-activated, polymeric sand in spaces existing between said paving blocks, and thereafter water spraying the sand to provide long-term stability to the finished paved surface;
- and
- wherein the sheet of foam material includes a grid marked on its exposed surface, said grid being arranged for positioning of said paving blocks.
