When choosing rocks for the construction of an alpine slide, it should be remembered that old stones that have been treated with water or wind are of the greatest value than those that were specially mined. Usually, boulders weighing from 12 kilograms to a centner are used for the construction of this structure. For the design of a rock garden, there is a huge number of stone formations, minerals and rocks.
Limestone is considered one of the most common materials. For example, you can choose stones such as dolomite, limestone and others. They gained such popularity due to the fact that their sharp corners are smoothed out very quickly, and, in general, such stones are quickly processed by the wind.
Sandstones are no less popular. It is important to note that they include quartz. These breeds have a wide range of different shades. They can be sandy, creamy gray or reddish. But, unlike calcareous stones, such stones erode very slowly and their sharp corners persist for a long time.
Granite stone is considered especially convenient for construction and an excellent decorative material. However, it has a number of disadvantages.
1) This stone is very cold and heavy
2) Easily acidifies the soil
3) It may take a long time for him to acquire a natural look
By using volcanic rocks, you guarantee that your structure will last a very long time, as they have increased strength. You can choose from volcanic tuff or basalt. Such breeds are very popular in landscape design due to the fact that they have a very attractive and beautiful texture and shape. It can be used when building terraces, creating imitation of weathered cliffs and strengthening slopes.
