How to Lay Pavers
How to lay pavers - this is how it goes step by step
If you want to pave your driveway, a walkway, the carport pavement or its terrace, this can be done with, among other things, baking stones. These paving clinkers are particularly hard-fired bricks. They can be laid in unbonded construction (on the split bed with moistened breaker sand as grout) or tied (on mortar bed with grout as grout). The type of lying depends on the loads that the finished plaster has to withstand later. For the paving of a sidewalk in the garden and a terrace at the house, the unbonded laying is completely sufficient.
If, however, the paving stones later are driven by cars, one should be bound by the tide. Otherwise, the construction is not stable enough and can sag. It is important that the substructure is flat and compacted. Also, a slope of 2.5 cm should be considered for the drainage of the rainwater.
In order to lay bricks, the following materials are required
- tape measure
- wooden stakes
- spirit level
- Surface vibrator with removable rubber surface
- pointing trowel
- rubber hammer
- Aluminum rail
- hose Connector
- Tiles Sponge
As building materials and auxiliaries we use ...
- A grit-sand mixture in the grain size 0/45
- Finished mortar
- Joint mortar
- Silicone rubber
Instructions for laying brick plaster
1. Preparing the excavation
You measure the area to be paved correctly, using a 5% area for the edge paving. Then you put the excavation all around with several wooden poles. The slope is laid down as follows: If you want to place a terrace and excavate a pit of 40 cm depth, attach a rope to the first higher peg at the base of the house at a height of 40 cm and pull it towards the pin where you can see it in 37, 5 cm high. From there, pull the rope to the next pin at the wall, where it is fixed at the height of 40 cm. Then pull it to the next facing peg, which is wrapped in 37.5 cm height, etc. The slope is then still controlled using a water scale.
2. Excavation of the excavation pit and placement of the mortar bed
The excavation pit is excavated with a space corresponding to the respective rope height. Subsequently, the substrate is pre-compacted with a surface vibrator. A supporting layer of a grit-sand mixture (grain size 0/45) is laid on this planar substrate in layers. Each layer is compacted with the vibrator to achieve optimum load bearing capacity. Then, five layers of 0.8 cm of water-mixed ready-to-use mortar are applied to make the bedding layer for the bricks. Each layer must be compacted with the surface vibrator before applying the next layer.
3. Laying the stones
You start in a corner and move the paving stones according to the later use of the pavement: If a pavement is to be paved, the pavement is laid in the path of the runner, the distances between the individual stones being determined by the joining trowel Rubber hammer hit. The joint width should be at least 0.4 cm. An expansion joint is applied every 5 m in each direction, which extends into the gravel layer below the mortar bed. For the paving of access roads, it is advisable to lay in the herringbone pattern. To achieve straight edge edges, an aluminum rail is used. Afterward, all outer edges are fixed with the aid of the masonry with an extended back support made of mortar.
For grouting, one can use the finished grout mortar available in every DIY store, which is directly mixed with water according to the instructions. Then the interspaces with the mortar mass are poured out. The expansion joints are filled with a permanently elastic material such as silicone rubber. After filling, all joints are recessed in the shape of a hollow core with a hose piece.
5. Cleaning and compacting
Every 30 minutes, the paved surface, which has already been finished, should be carefully cleaned of mortar residues as these can not be removed at a later date. Cleaned with a tiled tile sponge and water, which is frequently changed. To achieve optimum strength and load-bearing capacity, the hard paving piece is vibrated with a surface vibrator with a rubber plate. The rubber plate must be pulled up beforehand so that the bricks can not be damaged when they are stuck with the vibrator.
- When purchasing the joint mortar, you should make sure that it does not contain any blooms, as these leave ugly gray streaks in the rainy weather on the plaster.
- When mixing the joint mortar, it should be noted that it cures relatively quickly. It is therefore advisable to only apply as much mortar as you can have within a quarter of an hour.
- A brick plaster laid in a mortar bed can be cleaned with a high-pressure cleaner.
