The upper part of the rough tie consists of bottom concrete, reinforcing mesh and top concrete.
Concrete is poured over the drainage and leveled on its surface. The area of the poured concrete should be equal to the area of masonry stone, which must be put on the same day. This is done to ensure that the concrete does not dry out; the longer the concrete stands idle without stones, the more dust settles on it, and dust in turn creates gaps between concrete, mesh and stones - so the strength of the finished road will be much lower. Also, for good gluing of concrete, surfaces that are involved in masonry are poured with water. The layer of concrete is 5-6 cm.
The bottom concrete is made with coarse rubble, and a liquid consistency. The upper concrete, which is poured over the grid, is made with fine gravel and thick consistency: so that the stones stand exactly, without being tilted.
The composition of the concrete:
- 3 buckets of rubble, 20 kg each;
- 3 dropout buckets of 20 kg;
- 25 kg of cement M500.
Reinforcement mesh is placed on wet concrete and trimmed as needed.
