The geotextile that is sometimes called bidim is a protective film in synthetic material used by construction companies. But he also knows how to make himself indispensable in the garden.

Geotextile: advantages

If geotextile is also often used in various fields, including gardening, it is because it provides many services. Its advantages are numerous.

  • Rot-proof,
  • Solid, it is tear-proof, so it is necessary to use a cutter to cut it during its installation or to plant plants,
  • Allows air but also humidity and water to pass through, which is essential so that it does not stagnate at the level of the roots of the plants,
  • Limits the use of products harmful to the environment and to health such as herbicides, pesticides and insecticides because:
    • It prevents unwanted weeds from growing,
    • It protects plants from pests such as gastropods (slugs, snails), the processionary caterpillar, rodents,
    • It limits the development of invasive roots of certain plants, such as bamboo, which can cause damage to a wall or to the swimming pool,
  • Prevents drains from clogging with soil,
  • Stabilizes gravel paths,
  • Prevents stones from piercing the waterproof cover of a natural pool,
  • Allows you to plant plants that have specific needs in terms of soil when the soil in the garden does not suit them since it is enough to add good soil on the geotextile to solve the problem.

The geotextile can be laid in the vegetable garden, in the pleasure garden, under an alley.

Geotextile: how to install it?

It is very important to properly lay your geotextile so that it keeps its promises. The method to follow is as follows:

  • Completely clean the area on which you want to place the geotextile felt, which involves rigorously removing roots, loose stones and large stones, dead wood, etc.,
  • Flatten the ground with a roller so that it is well equalized,
  • Place the roll at the start of the area to be covered, making sure that it protrudes enough on each side, then unroll it,
  • Do not hesitate to overlap the lengths on at least 25 cm, if the case arises,
  • Cut the excess with a cutter or with a good pair of scissors,
  • Then fix everything either with sardines or with staples, knowing that this step is optional if the felt is covered with a sufficiently thick layer of earth or chippings.

All that remains is to cover the bidim with the material of your choice, leaving no visible part and using the back of the rake rather than teeth which could damage it. Depending on the project, we spread good topsoil, gravel, sand, wooden slats, or we put a slatted floor, or even a waterproof cover for the future basin …
