How to lay a concrete profile? The private access to the garage is classified as a light traffic area, therefore no special foundation is needed here. Regardless of, whether we are dealing with ordinary or concrete paving stones, the procedure is always the same: the top one is removed first, loose soil layer down to the hard ground. It must be at least 30-35 cm below the later layer of pavement. The substrate should be additionally compacted with a vibrator.
Now the so-called. carrier layer, or filtering thickness of at least 25 cm. The most suitable material is frost-resistant material, grainy, like for example. gravel or crushed stone. After whipping and leveling this layer, sand bedding is distributed. The type of ballast depends on the deposits in the area: it can be sand or stone fines (grain size 0/5 mm). The thickness of the ballast should be loose (before slaughter) 4-5 cm. This layer is not compacted yet, it will later be hardened together with the lined paving stones. Because the final height of the pavement surface is achieved only after compacting with a vibrator, it should be placed approx. 1 cm do 2 cm higher (depending on the material of the ballast). It is important to, so that the entire surface of the ballast is evenly distributed. It must not be walked on when laying – always work from the paved surface.
In order to avoid unnecessary cutting of concrete blocks, the first row is laid at right angles to the curb surfaces. Remember to keep the minimum gap. The joints are then filled with dry sand.
Stacked cube (absolutely dry) beat with a vibrator with a slip protector on, which protects the surface of the concrete blocks. If no curbs are used, the sides of the compacted surface should be concreted or secured with square timber, which will prevent the edges from sliding off. After compacting the entire surface, sprinkle it with sand again, so as to fill the gaps to the top.
Natural stone paving stones are embedded in the ground with a hammer with a rubber cover to the depth 3-5 cm. Then the gaps are filled and compacted with a vibrator, equipped with a hob – without sliding cover. The stones must be embedded in the ballast at an equal depth 2/3 their heights. The joints are filled with fine stone combined with bituminous mass or joint mortar based on cement-lime.
