We're seeing more and more clients request artificial grass installation on their rooftop or balcony. It's a great addition because it creates a multifunctional space for the entire family to enjoy. To learn more about the benefits of turf in these spaces, check out our other article here!

Although synthetic grass applications have many perks, they can quickly become a financial burden without proper drainage. Below we'll walk you through the drainage options we offer at InstallArtificial.

Why is A Drainage System Important?

If water builds up, mold and mildew can occur. Before installation, we must confirm that there is somewhere for rainwater and other liquids to go. We do not recommend installing artificial turf in any area that has an issue with water pooling. Fortunately, most balconies are designed and constructed with water drainage in mind.

When it comes to the drainage system, there are a few options that are considered. Before making a decision it's important to really diagnose which option will work best for you and your space. 

No Drain Layer

In this system, artificial grass sits on stitches and has holes every few inches in every direction. While this is not the best ventilation, water will eventually evaporate if the turf is under direct sunlight. However, the grass will hold water runoff which will lead to the growth of bacteria. We don't recommend opting out of a drainage system for this reason.

Drain Core

This is a flexible material. It allows grass to sit on a bumpy surface and breath efficiently. It also allows water to run off the roof or balcony quickly. While it is the most affordable drain grid, when walked on it produces a cracking noise if it's installed on a hard surface. Drain core can also expand under direct sunlight causing wrinkles (when not glued down).

Air Drain 

This is a rigid 1-inch tall material. It provides the best ventilation and fastest runoff. It expands moderately in the heat and doesn't show waves or inconsistencies. The shortcoming of this material is that high heels may puncture the grass not only damaging the turf but can result in injury. Heels should not be worn on this surface, making this drainage layer not ideal for areas where events are held.

Perforated Tile

This rigid and small celled tile is very durable. It is best for event areas. It was designed to survive heels and heavy furniture. The turf can also be glued directly to the tile for added convenience.

Soft Pad

Perfect for kids and low flow drainage. This option is often used in enclosed areas as it improves risks of uplift or must be glued down to the floor.

Without proper drainage, the longevity of your artificial installation will be greatly affected by the build-up of contaminants. Ignoring drainage can be a costly repair, and cause flooding to happen. Once flooding on your balcony begins it can easily run into the interior of your home.
