How to lay paving stones?

The selection of an appropriate material should be determined by the purpose of the paving. Depending on the loads resulting from traffic intensity that it will be subjected to, one should select material of various thickness: 4-6 cm in the case of narrow garden paths, 6-8 cm in the case of driveways and routes intended for car traffic.

A. Remove the top layer of soil (humus) to the appropriate level. Level and compact the bottom of the trough.

B. Prepare the right type of foundation for:

1. Sidewalks, bicycle paths, promenades
– Polbruk, thickness 6 cm, tiles, thickness 5 and 7 cm
– sand base, thickness 3 cm
– gravel foundation (hardened), thickness 5 cm

2. Estate roads
– Polbruk, thickness 8 cm
– concrete-sand base, gr. 3 cm
– foundation of B-7.5 concrete (or crushed stone), thickness 10 cm

3. Roads
– Polbruk, thickness 8 cm and 10 cm
– concrete-sand base, thickness 3 cm
– foundation of B-10 concrete (or crushed stone), thickness 15 cm

C. On the so prepared surface Polbruk is laid according to a pre-selected pattern. Polbruk has lugs that allow maintaining the thickness of the joint of approx. 3 mm. If necessary, paving stone should be cut on suitable guillotines or using concrete saws.

D. After laying, Polbruk should be compacted using a plate vibrator equipped with a Vulkollan or rubber plate.

E. Joints should be filled with dry and sifted sand with granulation of 0-3 mm, for example by sweeping it using broom .

Note! These methods of executing the foundation only apply to laying paving stone on sandy and gravel soils. In case of clay soils, an additional filtrating layer should be made (20 to 60 cm). In order to establish detailed rules of making the surface please contact road construction companies. Correct foundation, made of suitable material and laying paving stone made in accordance with the rules of paving are basic conditions of durability of the surface of paving stone.
