The paving processFoundation - must be stable, free from decayable materials, and able to safely transfer the load from the surface through the base course.
Base course - distributes the load taken by the clinker layer and carries away rain water.
Sub-crust - in the form of fine-grained gravel or coarse-grained washed sand, constituting a protective layer for the clinker (prevents the pavement from damage due to any undesirable stabilization of the ground) and simultaneously used to ensure the required downgrade.
Clinker layer - a surface resistant to abrasion, made from paving bricks of various colours, formats and shapes.

STEP 1 |
|
Preparation of a coarse-grained layer |
|
|
|
|
|
|
Materials and tools:
grader, shovel, compactor. |
|
A coarse-grained layer is made of soil free from unstable material. It is generally enough to level and compact the surface in preparation. |

STEP 3 |
|
Preparation of side framing |
|
|
|
|
|
|
Materials and tools:
mortar, clinker paving bricks, rod, trowel, putty, vibrating compactor, level line.
The side framing prevents the clinker paving bricks from moving while they are being laid and used. Paving blocks used to form the edge are laid on a cement mortar and reinforced from the outside with a layer of mortar. In order to avoid frequent cutting of the clinker, it helps to determine the distance between the edge and, for example, the house wall by laying a row of the clinker blocks with a 3-5 mm joint. The height of the clinker layer above the base course is calculated by adding the chosen clinker thickness to the sub-crust thickness (approx. 3 cm). The mortar foundation must be appropriately adjusted to the base course layer, with a downgrade of approx. 1.5-2.0%. |

STEP 5 |
|
Laying clinker paving bricks |
|
|
|
|
|
|
Materials and tools:
clinker paving bricks, 0-5 mm coarse-grained sand, strings, rod, abrasive-cutting machine or diamond saw, broom, rubber hose, vibrating compactor with a rubber cover.
Clinker paving bricks should be laid in a way that mixes bricks from different pallets in order to obtain a natural play of colours. You should start laying from the reinforced rim (side edge, walls, and steps) and first lay a couple of rows or a small area according to the selected pattern. In this way you will form a module, which, by means of strings, can be transferred onto the remaining area. Strings make it easier to mark the joints while laying further paving bricks. You must make sure that the same gap width, of at least 3-5 mm, is retained. In order to prevent the clinker from moving during work, it is recommended to fill the gaps with coarse-grained sand while laying the bricks. Smaller pieces must be cut with an abrasive-cutting machine or diamond saw. Before compacting the ready surface with a compactor with a rubber or neoprene protective plate, the joints must be filled with sand (0-2 mm). After compacting, the joints must be "closed" with coarse-grained sand. |
