In the modern landscape design, very serious positions are occupied by colored crushed stone. Get this bulk building material from rocks by crushing them. On an industrial scale, it is stained with special pigments that are harmless to both the environment and humans. Instead of the crushed stone obtained by crushing, gravel formed by the natural destruction of rocks can be used in the design.
Decorative crushed stone and Decorative gravel is a versatile material used to solve many problems in the field of landscape design. In particular, they are used for:
creating unique multi-colored compositions;
for producing single decorative elements and paving slabs;
fills in mosaic pads;
arranging bulk paths and plots;
design of the coast and filling the bowls of artificial reservoirs (using waterproof paint);
creating small architectural forms;
making decorative plaster;
arranging the blind area around the dacha house and household swill;
framing monuments and obelisks;
creating alpine slides;
simulating streams ( dry creek);
decorative concrete fences.
Choose colored crushed stone for landscape design because this building material has a number of advantages:
ample opportunities for design;
a wide range of products materials (fractions and colors);
long life of compositions created using decorative gravel for the garden;
operational safety for people that is important for arranging tracks and playgrounds, including play areas for children;
if necessary, colored gravel backfill can be easily removed, with a shovel and a capacity for carrying the breed;
the appearance of the composition using colored stones is easy to update and refresh;
dusting decorative stones of lawns and flower beds prevents the top soil from drying out, does not allow the weed to grow grass;
under the influence of moisture, ultraviolet radiation, low and high temperatures painted gravel retains its attractiveness for a long time;
for colored gravel compositions, no care is required other than removing sprouting plant shoots and periodically leveling the surface (if someone accidentally stepped on it).

Before dyeing crushed stone for landscape design, the possibilities of natural stone colors are usually considered. They make it possible to lay the foundation for a future composition, the filling of painted crushed rock is the final stage of decorating the space of the summer cottage. In particular, the natural rock used for decoration has the following shades:
marble — white-blue, white, black, pink, honey;
flint - red and pink;
jasper - sealing wax;
serpentine - a mixture of greenish-yellow and dark green;
quartzite - golden, milky-beige, crimson, olive;
gravel - the predominant black and gray shades.
Colored crushed the rock (granite or marble) has brighter shades that distinguish it from natural: red, gray, green, orange, blue, yellow, pink, etc. For decorating, stone 5-10, 5-20, 10-20 is usually used 20-40 mm.
In addition, a tinted stone can vary in parameters such as flakiness (ideally up to 15%), frost resistance, degree of abradability, compressive strength, density, specific activity of radionuclides. The value of radiation must be confirmed by an appropriate certificate.
The cost of decorative material is of the order:
from 4,500 rubles per ton of unpainted natural stone;
from 30 rubles per kilogram colored stone;
from 20 rubles for a galtovanny (stone that has undergone abrasive treatment);
from 900 rubles per ton of decorative sand.
As a raw material for the manufacture of the material, stone chips of a certain fraction and acrylic paint are used. If the raw material is stone chips not sorted by fractions, then the first technological stage will be the separation into fractions by sieving on a vibrating screen (vibrating screen).
The next stage is painting, it uses a painting bunker, the principle of operation which is similar to a concrete mixer. The volume of paint loaded into it is about 20% of the volume of crushed stone loaded. After staining, the crushed stone is moved to the drying chamber, after drying the stone is packed in bags weighing from 2 to 20 kg.
There is a risk of acquiring a poor-quality decorative material. These are mainly products of small enterprises, which at the expense of quality can save on:
the amount of paint put into the bunker;
drying chamber (drying is carried out simply in the air on a polyethylene film).

The first operation is marking the area where the composition will be created using colored gravel. This is done with the help of pegs and rope, which are stretched, connecting the pegs into one geometric shape (square, rectangle, polyhedron).
If you plan to arrange a round platform, you can apply the compass principle. For this, a stake is driven in in the center of the future circle, a cord is put on it to the free end of which a can of paint is attached. With the help of a can the circumference of the desired diameter is outlined.
A layer of naturally established soil is removed to a depth of 10 cm on a marked area of land. Limiters are placed on the outer borders of the territory: tape, curbs, natural stones, boards, metal or plastic strips, corners, etc. Depending on type of the selected limiter, its installation can be carried out directly on the ground with the exposure level, and on the prepared cement-sand pad.
A layer of sand is poured on the surface inside the shape of the limiters in 5 cm. It is tamped and shed with water to prevent shrinkage. An alternative and more fundamental option is the device of a concrete screed on a sand pad. The next layer is a waterproofing material, after its laying another layer of sand 3 cm thick is poured.
If you plan to create a pattern inside the figure, then first limiters are placed inside it. Finishing stage backfilling and leveling of decorative colored rock. The usual consumption of gravel per 1 square meter when laying in a thickness of 2 cm is about 2 kg. In the case of arranging a site or walkway with the use of decorative gravel, which people will walk on, the thickness of the main layer of sand increases to 7-10 cm, gravel also to 7-10 cm.

The use of colored gravel in landscape design is a simple and inexpensive way to decorate a summer cottage. Moreover, it is possible to create from gravel not only compositions for decoration, but platforms and paths along which people will walk. The only condition for obtaining the desired result is the acquisition of stones with the required parameters and compliance with the technology when laying gravel. It is better to entrust the choice of material and its installation to specialists.
