Artificial grass, is it water-permeable?

The weather has become increasingly extreme in recent years. More and more often we have rain showers that last for a long time and that are then followed by an extremely dry period. All these enormous amounts of water also have to be processed in our gardens. Due to climate change, it seems that nothing will change in the coming years and that these unpredictable rain showers will occur more often. It is therefore necessary to take measures to protect the garden against possible major flooding. Artificial grass must therefore be water-permeable and thankfully it is.

How does artificial grass work when there is a risk of flooding?

Fortunately, artificial grass has an extremely good water permeability, because it is provided with very small holes that allow the water to drain away quickly. The water does not remain on the lawn, because it can quickly seep into the soil. If the water cannot drain away quickly, it is stored in the grass. You must then use a subsurface that has a shock-absorbing effect, because it has an absorbent effect. If the excess water can penetrate the soil, it will slowly disappear from the grass into the earth. This is of course also very good for the environment, because the soil remains moist for longer and the soil is not too wet. It is very important that artificial grass is installed correctly and cleanly. The subsurface is very important here, it must be ensured that it is water permeable. If the subsurface does not allow the water to pass through easily, it is possible that the water will get stuck between the underlayer and the grass. This can cause a build-up of water, which can cause folds in the grass.

The following reasons can be a cause of flooding if there is artificial grass in the garden:

The surface is unsuitable

The water cannot be properly drained towards the ground

Water is drained into the lawn through the paving

The artificial grass has been laid incorrectly

How is artificial grass water-permeable?

Artificial grass is water-permeable because the backing is provided with many tiny holes. However, these holes are just big enough to allow water to pass through. This in turn ensures that the artificial grass is water-permeable. Per square meter, about sixty liters of water per minute can steam through the artificial grass and in this way it can easily drain away even during huge downpours, but only if the artificial grass is installed properly.

The substrate and water permeability of artificial grass

Artificial grass is often installed on a sand base. Make sure to approach this seriously and in the right way. If you install artificial grass on soil or black sand, it will not work well. Black soil sinks easily, but there can also be problems with water drainage. Black sand cannot drain water as quickly. It is therefore better to opt for concrete granulate or a base of mixed granulate. In addition to the fact that these bases are a good
water permeability, they also provide a base that is extremely sturdy. The artificial grass will then remain beautiful after years. If the base of artificial grass consists of clay, you can consider using the enormous water permeable lava, so that you have a good base for your artificial grass. A well-known property of lava is its perfect drainage effect.

Do you want to lay artificial grass on a concrete floor or on the balcony?

Then keep in mind that the water must be drained properly. You could use a special draining artificial grass for this. By means of mats that are shock-absorbing, it is ensured that the water runs through drainage holes. In this way, the excess water is buffered and the water can be slowly released into the environment.
