If we decide that rainwaters are to be discharged under paving slabs, we may lay them in few ways:
- use spacer disks, not adjustable (dry method) –lay slabs on a stable, waterproof surface, the angle of slabs will be adapted to the angle of the surface, which provides for water discharge
- use spacer disks, adjustable (dry method) – lay slabs on a stable, waterproof surface; applied discs allow on perfect leveling of slabs.
- use spacer disks, adjustable (dry method) – on the foundation made of concrete drainage
- use plastic bags with mortar (wet method) – lay slabs on a stable, waterproof surface; plastic bags are placed in the corners of slabs, lay slabs on plastic bags and level them, then water the mortar through pouring water.
