The stability of the paving surface

How to fill the joints?
The point is, whether it is to be a joint filled with mortar or sand? The joints of the paving surface are most often filled with quartz sand, which reaches the tiniest cracks. After the surface has hardened, a vibrator is used to fill the joints with dry sand, all the way to the top edge. When the joints are very wide, then they can also be filled with grit. The material used to fill the gaps ensures the stability of the stones.
If the space between the cube or block is filled with sand, then grass or weeds may grow from it, which, however, can be easily spouted. Who wants the perfect cladding, it can fill the joints with a special frost-resistant mortar.

How to ensure the stability of the paving surface
Each pavement requires edge reinforcement. This is not necessary for garden paths, which are slightly loaded. Then the paving stones can only be separated from the lawn by gravel or even be directly adjacent to it. In this case, only the concrete strip of the foundation in the place where there is a risk of removal is sufficient. More heavily loaded surfaces, mainly access to the garage, should be framed with concreted curbs. First, the curbs are attached, and only then paving the way. In this way, the whole thing is stable.

Repair of damaged surfaces
If the substrate has been made incorrectly, then the pavement settles unevenly. Not every contractor complies with the requirement to compact the substrate and the base course. This results in wobbly dice and uneven surfaces. Such faults can trip you and spoil the overall effect. Often times, it is not enough to replace individual fittings. Then you need to correct the bedding and put the block back on. If the defects are significant or the surface is very uneven, then you have to do all the work again, and so: remove individual layers, harden the substrate, apply the load-bearing layer and, after tamping it, put a thin layer of bedding under the ankle.
