the hidden elegance of drainage on a terrace, in a garden or a courtyard

In terms of outdoor development, the drainage system fulfills a functional aesthetic role. Currently, innovative drainage solutions make it possible to avoid problems linked to water stagnation while embellishing outdoor spaces thanks in particular to the use of quality materials and pointed installation techniques.

The importance of drainage in outdoor spaces

In a garden or courtyard, or on a terrace, a good water evacuation is essential to avoid any damage caused by the stagnation of water. It is precisely in this specific context that a drainage system comes in. It will help particularly evacuate rainwater and watering to a collection point, allowing you to keep your outdoor space always dry and secure while preserving its aesthetics and the sustainability of the coatings.

On a terrace, excessive humidity due to the accumulation of surface water can cause discoloration of soil coverings, weaken them and accelerate the development of molds making the soil particularly slippery. Not to mention the fact that water infiltration may weaken the structure of the terrace, or even the foundations of the house.

In addition, in a garden, the water that stagnates leaves the soil constantly damp, which can cause many problems. A soil full of water can harm the health of the surrounding vegetation which most often results in root rot, as well as in the development of fungal diseases¹. The puddles permanently also create muddy areas that make the garden impassable to ultimately alter the general appearance of your garden.

In a courtyard, a poor evacuation of rainwater will inevitably generate puddles of water which will not be to the taste of users before crossing it.

Discreet and aesthetic drainage solutions

You should know that it is possible to install a drainage system without having to urge your outdoor space. A well thought out drainage system not only avoids the various problems related to stagnation and water infiltration, but also to bring an aesthetic touch to perfect your outdoor layout.

The slit channel: an aesthetic and invisible solution

The slit channel has the advantage of integrating harmoniously into the landscape while ensuring effective drainage. Unlike the grid channel made up of apparent grid which covers the gutter, the slit channel has a narrow slit which forms a thin line which serves as a opening for water evacuation.

Practically invisible, ULMA slit channels allow for example integration without visual rupture with the floor covering. On a modern terrace, details such as the stainless or galvanized steel slit grid of Ulma are completely based in the decor while providing a clean touch thanks to its fine and elegant design. Beyond its aesthetics, this type of material has great resistance and sustainability, which represents a real advantage for areas with high passage.

The draining gravel for a natural and discreet rendering

For optimal drainage, the draining gravel turns out to be an excellent choice for those looking for drainage solutions that are both aesthetic and practical. Line a courtyard with gravel indeed guarantees a good flow of water thus preventing the formation of water puddles. But its large asset lies in its ability to adapt to any style of outdoor development. In a modern outdoor space, adding draining gravels around a concrete terrace brings a very trendy design effect. In a garden or on a rustic style terrace, the association of wood and gravel creates a contrast to the surrounding greenery.

The vegetated drainage system for natural drainage

Another solution for invisible drainage is to create a vegetated area which will be perceived as a natural decor in its own right in your garden or around your terrace. It consists mainly of absorbent plants (eucalyptus, willows …) which will absorb humidity in the ground and at the same time embellish the places with their colorful flowers and their lush foliage. The use of draining materials such as gravel is also to help evacuate excess water.
