Guidelines for laying clinker paving stones.

The quality of the paved surface and its durability depend not only on the properties of the paving stone itself, but, first of all, on the base and the bearing layers of soil located under it.

When laying clinker paving stones, it is important to follow certain rules and recommendations.

Briefly about the most important

  • in accordance with the purpose.
  • Preparation of a stable, frost-resistant and permeable base structure.
  • Laying a bedding layer of a suitable material (mixture of crushed stone with a grain size of 0-5 or 0-8 mm). The thickness of the layer in the compacted state should be 3-5 cm.
  • If you are using recycled materials in your bedding, it is advisable to pre-test them for the possible presence of soluble substances that can cause salinity on the surface.
  • Because clinker paving is a natural material, slight color variations within the same batch and also between batches are allowed. Therefore, we recommend using paving stones from several pallets at the same time, mixing them.
  • The recommended slope of the surface is about 2.5%
  • Joints 3-5 mm wide should be left between the elements of the paving stone, so that during installation and operation, chips do not form at the corners and edges of the elements.
  • The interaction of pavement structural elements is achieved by filling the joints with crushed sand or fine gravel with a grain size of 0-4 or 0-5 mm.
  • Immediately after laying the clinker paving stones, sweep the sand into the joints, then re-sweep with finer sand (grain size 0-2 mm) and rinse with water.
  • Compact the paved surface with a vibrating plate with a rubber pad.
  • Sweep again with fine sand and rinse the seams with water.

The choice of clinker paving stones.

Paving stones should be selected in accordance with the scope of use and purpose. The choice of the right material determines its function and service life, but the correct use and care of the material is just as important.

For the construction of pedestrian and garden paths, terraces, etc. you can use paving stones of all thicknesses (45; 47; 52; 62 or 70 mm). On roads with constant traffic of public transport or other heavy vehicles, pavement elements with a thickness of 70 mm or more should be used. For lighter pavements of pedestrian, bicycle paths and roads for cars, paving stones with a thickness of 62 or 52 mm can be used (if there is a good basis for this or good experience).

Base device

After planning and appropriate preparation of the soil, a bearing layer should be created.

The structure of the bearing layers and the choice of their thickness depend on the expected load, especially on the intensity of traffic on the paved surface, as well as on the expected climatic conditions.

The carrier layer must be durable, frost-proof and water-permeable. To do this, lay a layer about 25 cm thick of crushed stone or gravel, (grain size 0-32 mm), (this option applies to the construction of pedestrian and garden paths, terraces, etc., in the case of the construction of streets and roads with constant traffic public transport or other heavy vehicles, the bearing layer must be designed and developed in accordance with relevant standards and building codes). With several layers, it is desirable that one be about 15 cm thick without fine particles in order to avoid capillary rise of water. Crushed stone (or gravel) is laid and compacted with a vibrating plate in layers in several approaches, until the required stability is achieved. The bearing layer in the compacted state must also be water-permeable and with a slope of about 2.5%.

Bedding device

The device of the litter layer with a thickness of 3-5 cm is carried out from a gravel mixture or crushed stone of a fraction of 0-5 mm, or 0-8 mm. Crushed stone is preferred, which contains fewer fine particles and provides faster water runoff. The material of the bedding layer must be sufficiently hard, well compacted and free of soluble substances (salts, lime, etc.), which can then cause salting on the surface of the pavers in the form of light spots. The material must be leveled with a rail and guides, after which the guides are removed. The remaining furrows should be filled with the same material. Instead of smoothing guides, you can use already laid paving stones. In this case, cutouts of a suitable size should be made at the ends of the rail.

The smoothing of the bedding layer as well as the carrier layer is carried out at a slope of at least 2.5% in order to ensure the same slope for the finished pavement pavement.

Laying clinker paving

The delivered clinker pavers should be checked visually before laying. Any differences in quantity or quality should be resolved before laying.

Paving elements with visible defects should not be laid.

To make the finished surface look more even, it is recommended to lay paving elements simultaneously from several pallets, mixing them.
