Geotextiles for garden paths: 5 tips for choosing and laying

5 min


Have you ever wondered why some tracks last for decades without much damage, while others begin to deform the next year after laying? If you thought about it, you probably could have assumed that in the second case, serious mistakes were made at the installation stage. And there is. There can be many mistakes, but one of the most serious is the failure to use geotextiles or the use of inappropriate material. To prevent unpleasant consequences on your site, we will figure out which geotextile to choose for garden paths and how to install it correctly.

Why do you need geotextiles when arranging garden paths?

Garden paths are an important decorative part of any site. In addition, serious functions are assigned to it. At a minimum, the path should be strong and durable, not sag under the first rain, not deform from the roots of trees, regardless of what material it is made of. Geotextile comes to the rescue – a synthetic material that is made from polymer threads.

Geotextiles differ in the method of production, density and dimensions of the canvas – the most suitable material is taken for different purposes. The main thing is that the geotextile is of high quality and can fulfill the functions assigned to it. To be sure of quality, it is better to buy material from a trusted place.

Residents of St. Petersburg and the region can order geotextile in the company “Resource”, which is a distributor of large domestic and foreign manufacturers, therefore can guarantee quality and the most favorable prices. If necessary, experts will help with calculations and suggest the most suitable type of geotextile.

Geotextile performs the following functions:

  • protection of the track from deformation, the formation of internal voids and precipitation under the influence of rain, snow and loads. Without geotextiles, the crushed stone base of the path easily sags into the soil layer below it, provoking the formation of voids and subsequent destruction. The use of geotextiles allows you to keep the rubble in place and prevent consequences;

  • effective removal of moisture from the track due to the high moisture permeability of the geotextile;

  • protection of the path from the destructive effects of the roots of trees and shrubs;

  • protection against germinating weeds;

  • increasing the level of resistance to stress;
  • protection from dirt, since the layer of soil and sand is separated;

  • soil strengthening on slopes;
  • the possibility of local repair of the track.

Geotextiles have a small mass, are easy to transport and install, but they are afraid of ultraviolet radiation, therefore it is better to work with it as quickly as possible.

Types of geotextiles by material

Geotextile is used not only in the arrangement of garden paths – it is necessary in the construction of roads and foundations, when performing drainage works. For all these cases, a material with different properties is required. That is why geotextile production technologies and materials used differ.

By the type of raw materials used, geotextiles are:

  • polyester (polyester) geotextiles are made from thin polyester fibers. It turns out an environmentally friendly, but not very durable material that does not withstand the effects of many environmental factors, is afraid of acids and alkalis;

  • polypropylene geotextiles are more durable and durable, resistant to the external environment, perfectly conducts moisture, does not rot;

  • blended geotextile contains safe recyclable materials, incl. threads of cotton and wool. It turns out a cheaper material, but much less strong and durable than its counterparts. Natural yarns quickly rot, creating voids and reducing the effectiveness of geotextiles.

For garden paths, polyester or polypropylene geotextiles are suitable.

Types of geotextiles by manufacturing technology

Depending on the characteristics of production, geotextiles are:

  • needle-punched is obtained by bonding polypropylene or polyester fibers in a special way, due to which the ability to pass water along and across the fiber is achieved. The material will not be clogged with soil particles and flooded with water;

  • thermally bonded is obtained by fusing fibers with each other, due to which record strength is provided, but weak filtering ability – water passes only in the transverse direction;

  • stitching is obtained by weaving fibers. It passes water well, but does not withstand the effects of many external factors, it is unstable.

For garden paths, it is best to take a needle-punched geotextile, although many allow the use of thermally bonded material.

Density of geotextile

When choosing geotextiles for garden paths, it is imperative to pay attention to the density of the material. It is believed that the higher this indicator, the better the material in front of you. Density ranges from 17 to 600 g / m2 or more. The thinnest geotextile is used to protect soil from birds, to cover greenhouses and greenhouses.

For the organization of garden paths, material with a density of 100-250 g / m2 is useful. The choice is best made based on an analysis of the type of soil and the characteristics of the site. So, if the territory is flat and the soils are stable, then it will be enough to use geotextiles of 100-150 g / m2, if the soil is mobile and unstable, then it is better to take geotextiles with a density of 250 g / m2 and even more. In most cases, they stop at the 150-200 g / m2 option – this is an excellent ratio of strength and price.

How to lay geotextile

Of course, it is not enough to choose high-quality geotextiles – you still need to correctly mount it to ensure the stability of garden paths. The surface of the track can be any: asphalt, tiles, wood cuts, gravel, stone, decking, brick, etc. For example, consider the use of geotextiles when installing a paving slab track:

  • the boundaries of the future track are marked on the ground. In some cases, it makes sense to lay the tiles on unprepared soil, but you can do without it;
  • excavation is provided to a depth of 35-40 cm (depending on the thickness of the sandy, crushed stone layer and the tile itself);
  • all garbage, tree roots are removed from the bottom of the trench, thoroughly rammed;
  • laying geotextiles at the bottom of the trench, the overlap of the canvases – at least 20 cm, the material should also cover the walls of the trench and come out to the surface by 5-10 cm. For fixing, stones or other improvised items can be used;
  • a layer of rubble about 15 cm is laid, carefully leveled;
  • crushed stone is covered with another layer of geotextile;
  • fine-grained sand is poured with a layer of about 10-15 cm, it is rammed with high quality, and the tiles are laid on it. Many craftsmen recommend making the laying layer from a mixture of M500 cement and sand in a ratio of 1: 4, i.e. where 10 cm can be covered only with sand, the remaining 5 cm – with a mixture;
  • the tile is rammed with a rubber mallet, it sinks well into the mixture, if necessary, trimming is performed, the seams are filled with the same cement-sand mixture or sand;
  • remnants of geotextiles are trimmed, curbs are installed.

Even if it happens that some tile sags, you can get by with a local quick repair. The tile rises, sand is poured under it, the tile is installed back and rammed. With proper installation, repair work will have to be carried out extremely rarely.

Note that there are many manufacturers of geotextiles on the market, so it is very difficult to list at least some of them. When buying, do not be lazy to study product reviews so that the work performed is not in vain.
