Uni COLOC pavement is designed for industrial area laying. The cobblestone shape secures the key principle of the laying method, which is often used in facilities with a high load carrying capacity, as well as providing more effective specialised pavement laying equipment that can be used.

Laying the cobblestones:
Setting up the base and leveling the layer profile, should take into account that the paving surface after installation and vibration has to be about 5-10 mm above the curbs, during a period of time substrate compaction is occurring.
Applied paving thickness depends on the load and transport intensity:
– Thickness 50 mm (T-5) – pavement paths;
– Thickness of 60 mm (T-6, T-6-1; Vent 6) – pavement paths, possible light intermittent transport movement;
– Thickness of 80 mm (T-8; Nostalith L + M; Nostalith V; Antik; Uni COLOC; Vent 8) – carriageway entrance and parking;
– Thickness 120 mm (T-12; Behaton) – container fields, port terminals, factory warehouse areas.
Sidewalks, paths, roadways constructed before cobblestone adjustment is desired in order to lay paving stones , specific patterns and a certain profile, to determine the required space between the edges, because of possible technological tolerance paving sizes. This will prevent unnecessary paving custom cutting.
Correct lines and angles to create a string and goniometry assistance every 5-6 layers of control, if necessary, with crowbars, straightening lines and spaces.
Pavement with spacers (typically 1.5 mm) required for the production process, the fitting, this spacing is small. The thicker paving, clearance must be greater. Optimal construct cobblestone must be 3mm, paving stones with h = 120mm clearance must be 5 mm. It is particularly difficult to observe up with machines, so manually increased spacing of at least 3 mm. Stone is used for the recovery of rubber hammers, space increase – crowbars.
Paving colour and marking, varies depending on the humidity of concrete, filling material colour tone, it is therefore necessary to carry out the laying of pavement from 2- 3 pallets simultaneously. During the laying with special machines, it is not possible and can form a chess wise tone coating, depending on the load, the differences will disappear in 4-5 months.
If necessary, paving stones are cut with special saws, subject to certain plant characteristics of the saw blade (diameter; wet, dry or in combination; the direction of rotation). Pavement spaces are swept, so that there is no spaces in between the cobblestones.
The spaces are filled with sand fr.0-2; 0-4 mm. In a broader space, the coarser material by the formula: 0.8 x space.
Space filling is a very important element of work for laying a pavement , it depends on the total pavement longevity.
The sweeping is done with brushes or special equipment. Wet sand wash into the gaps.
Paving surface is swept from excess coating material and the planking is vibrated.
After paving vibration is repeated, the sweeping of the joint is performed , so that there is no spaces in between the cobblestones.
Requirements for the pavement surface:
– Height marked to design ± 2 cm
– Width ≤ 5 cm
– Plan ≤ 5 cm
– Cross-profile ≤ 0.5%
– Slit> 3 mm (depending on the paving h)
– A clearance between adjacent
existing rocks <3 mm
– Plain (3 m lath) ≤ 6 mm
Carried out by surface vibrators according to the paving thickness. Shaker weight must be:
– H = 60-80 mm – 100-150 kg; 18-20 kN
– H = 80-100 mm – 150-200 kg; 20-30 kN
– H = 100-200 mm – of 200 – 300 kg; 30-50 kN
Vibration is done from the edges to the middle, covering the previous vibrated side each time. Each area has to be vibrated 3-4 times.
15 Vibrating plates equipped with a polyurethane plate , if, colourful and structured paving stones have to be vibrated – in the rain. Vibrating rollers cannot be applied.
After vibration , the area must be smooth, if necessary, other spaces have to be extra vibrated. CRITERIA TO ASSESS THE MATERIALS BEFORE INSTALLING.
External surface may have surface pores encountered during manufacture. Uneven surface increases the stiffening ability, prevents slipping, technically this surface is more valuable than a smooth surface. To highlight the concrete structure, prevent sliding, paving stones can be ordered, curbs with a structured surface, using special equipment for surface rinsing or mechanical processing which does not alter the technical characteristics of the material.
Detailed Tear down cracks may occur, which appear only after the rain, humidity after drying. Such detailed cracks using this product does not diminish opportunities.
Colour differences in separate pallets can be offset the colour hue (also neither dyed materials) resulting from the production process of concrete moisture or material colour offsets, which is not technically avoidable. Therefore, preferably at the same time take material from at least three pallets at the same time. More of a problem occurring with the mechanical coating. However, this slight colour difference will be lost in the next 3-4 months, especially if the surface is intensively exploited.
The white efflorescence occurs when the concretes existing Ca2 ++ dissolves through the porous concrete, water gets on to the surface of the products, the water evaporates and calcium hydrate reacts with carbon dioxide in the air, a white solubility of calcium carbonate Ca (OH) 2 + Co → CaCO 3 ↓ + H2O Possible causes: insufficiently dense surface un-filtering basis, insufficient drainage, insufficient water abstraction. Remedy: – lost during 1-3 years depending on the load intensity;
– Cleaning with hydrochloric acid and immediately rinsing with water;
– Mechanical cleaning.
