How to lay terrace tiles on the ground?

You should start by marking out the surface of the terrace on the ground. When we mark out our dream terrace, it is necessary to correct the ground. Depending on the substrate, it is carried out at a depth of 20-30 cm. In the case of cohesive clay or clay soils, it is recommended to spread the geotextile directly on the substrate to prevent the penetration of impurities from the soil onto the slabs. The substrate should then be cleaned of branches and stones, leveled and compacted with a compactor. A layer of up to 10 cm of sand, not thicker, is spread on the leveled surface. It should also be compacted with a compactor, while profiling the slope through which the water will drain. The next step is to make the foundation, which is the load-bearing layer of the terrace. Natural aggregate is usually used for this. The thickness of the foundation should be about 20 cm. The next layer is a 4-centimeter ballast made of 2-8 mm fine grit.
