Drainage is the process of dispersing rainwater into the soil. Drainage is essential for restoring lawns or gardens where, for various reasons, water stagnates , turning lawns and flowerbeds into swamps, killing grass and plants. Unresolved stagnation can lead to rot, asphyxiation, and the growth of moss in your garden.

Various techniques can be used. You can create shallow channels that collect water and channel it into a deep well filled with stones, through which the water slowly disperses into the ground.

Another system consists of creating a network of plastic pipes , buried 10-15 cm underground and perforated at the top, so that the water that enters them can be conveyed away, towards a common collector.

The most radical system, but also the most laborious to implement, involves removing 30-40 cm of soil, filling it with coarse gravel, and covering it with soil mixed with sand. This ensures the entire surface is consistently drained.

In particular, the choice of drainage technique is naturally also linked to the type of soil.
