The concept of fences is often associated with various vertical garden elements with similar functions. Low walls, elevated curbs, Small precipitral hedges are often used on the border of pedestrian surfaces with surfaces covered with vegetation. They are not difficult to overcome an obstacle, and yet very often they effectively protect different surfaces from trampling.
Low height walls to 45 cm can be, After adequate adaptation, used for sitting. Higher hedges and walls built inside the garde.
The plastic form of the fence may be different and depends on the factors mentioned above and to a large extent on the adopted material and structure. Fences of garden facilities should be as easy as possible in construction, no exaggerated decoration. You can even recommend making discrete fences that do not distract attention from the decorative values of the interior - the garden.
When choosing the structure, the occurrence of factors affecting the destruction of fences should be taken into account.
We include these factors:
– soil movements due to settlement or freezing, wind,
– material corrosion,
– roots or above -ground parts of existing trees,
– vandalism.
Soil movements caused by settlement or freezing cause cracking of foundations and plinths; This leads to the deviations of the line and the fence plane. This can be prevented by stabilizing the ground, deeper foundation or avoiding rigid structures and the use of more flexible.
Wind forces are particularly dangerous to full fences (walls) located transversely to the direction of the most urgent winds. This forces can only be prevented by giving the wall appropriate stiffness, np. by using purchase. Openwork fences covered with vines can also be destroyed by the wind, especially in a state of foliage.
The corrosion of material reduces durability, Mechanical properties and aesthetic features of the fence. Natable materials should be used, surface and deeply protected against corrosion.
The roots of trees near the fence can choose pressure on the foundations during growth, causing them to crack and displace them. A thick trunk may exert a similar effect. This can be avoided by avoiding trees with a fence line at least at a distance 1 m. Such solutions are a pleasant variety of fence and emphasize the decorative values of the tree.
As a result of vandalism, easy -to -break materials are particularly easily destroyed (wooden strips), easily cracking (plastic plates, thin prefabricated concrete elements) and similarly not resistant materials. The use of such materials should be avoided when making external fences.
