Basically, during construction, they resort to the construction of formwork cast from concrete, for which it is then necessary to align the upper part according to the slope of the terrain. To make the structure stronger, they resort to sheathing with its boards. However, before disassembling the formwork, it is worth considering its structure. It is noteworthy that in the process of manufacturing, it is allowed to use a variety of materials, for example, plastic, but you need to carefully consider the solution, because for some tasks it will not be quite strong. As a result, the formwork can collapse when filling the screed. A more common solution is the use of related boards. Here we note that when dismantling is required, difficulties may occur. As a result, the best option is a plywood of increased strength, and the dismantling of this design is carried out simply. By the way, now very often they began to order air heating, it can be found in every country house.
Nevertheless, there are disadvantages in plywood, namely, seams. Over, you can resort to sealing with an appropriate solution. In addition, during the implementation of the rounded design, you will need to be guided by other factors, for example, it is important to clearly represent the purpose of the final structure.
