Selecting the appropriate materials for paving slab installation is essential for both longevity and aesthetic appeal. The gartsovka, a mixture that gives the slabs a firm and stable base, is one of the key ingredients.
Sand and cement are mixed in precise amounts to create gartsovka, which has the ideal ratio of flexibility to strength. By providing support, this mixture keeps the slabs from moving and cracking over time.
You can accomplish the greatest outcomes for your paving projects by being aware of the components and operation of gartsovka. Let’s examine the essential components and how they work together to build a solid base for your paver slabs.

The basic concept of gartsovka and its varieties
In its traditional form, gartsovka consists of a combination of quarry sand and dry cement. Such a composition finds wide applications, ranging from internal wall plastering to paving slab application. The process of creating these compositions varies depending on the application.
Types, further classified based on the quantity of components utilized:
- simple – a two-component dry mixture consisting of a binder – lime, cement, gypsum and filler – sand, dolomite, calcium, expanded clay or marble flour;
- complex – up to five components are used in such compositions. For example, gypsum and clay are added to a standard cement-sand mixture.
Gortsovka is separated based on composition based on the material fractions:
- light gartsovka – has small fractions of all components, which should be no more than 1.25 mm;
- heavy gartsovka – when creating it, raw materials with a granule size of no more than 2.55 mm, but not less than 2 mm are used.
It is not appropriate to mix gartsovka with cement mortar. In contrast, gartsovka is a dry mixture, whereas a composition based on cement contains some water.
The mixture can have any strength grade, contingent on the intended use of the approved grating:
In addition to strength, there is a difference in the quantity of cement added, correspondingly. In other words, the mixtures’ colors and consistency will vary.
Advantages and disadvantages
It is very profitable to prepare and use such a composition yourself because the prepared mixture has the following indisputable benefits:
- it is possible to mix a large amount of the composition in one go;
- the prepared mixture has a good shelf life;
- a coating is created that can always be restored to its original state;
- the mixture is made of environmentally friendly materials;
- relatively low cost.
However, there will always be a "fly in the ointment," just like in any "barrel of honey":
- mixing the components is more convenient and better quality on a flat concrete floor than in any container;
- you need to be careful when dosing the components and selecting according to grain composition. For example, a small amount of cement can lead to cracking of the finishing layer. Therefore, if you are not sure of your eye, it is better to buy a ready-made mixture, where all the quality nuances and issues of component compatibility have been resolved by the manufacturer.
The main area of application of gartsovka
Like many years ago, gartsovka has many uses in modern times. However, floating floor construction is its primary application. It is also the primary ingredient in masonry mortars and plasters, which are perfect for working with aerated concrete. The mixture is frequently used as a putty to extend ceilings as well as walls.
Nowadays, high-quality gartsovka is widely used for self-laying pavers or stones. With its practically penny cost composition, it is perfect as an adhesive base, producing excellent adhesion.
To obtain long-lasting and aesthetically pleasing results, it is crucial to comprehend the composition of gartsovka for paving slabs. The stability and durability of the paving slabs are guaranteed by using the proper ratio of sand, cement, and water.
Sand of the highest caliber supplies the required strength and smoothness, and cement serves as the binder to keep the mixture cohesive. Water activates the cement in precisely the right amounts, allowing the gartsovka to set correctly.
These materials can be carefully chosen and combined to provide a sturdy base for paving slabs that can endure bad weather and high traffic. A well-prepared gartsovka makes a big difference in how well your paving projects perform overall and look.
For paving slabs, gartsovka is made up of a mixture of cement, sand, and occasionally extra ingredients like plasticizers to improve workability and durability. This mixture gives the slabs stability and weather resistance while ensuring a robust, long-lasting foundation. Achieving a smooth, even surface and extending the life of the paving slabs require an understanding of the proper proportions and types of materials used in the gartsovka.
