Installing an artificial lawn base is a crucial step in creating a beautiful and long-lasting outdoor space. A well-prepared base is essential for a successful installation.

The ideal base depth for artificial turf is between 4 and 6 inches, depending on the specific product and local building codes. This depth allows for proper drainage and prevents the turf from settling unevenly.

Proper drainage is key to preventing water accumulation and erosion. A well-draining base helps to prevent puddles and reduces the risk of damage to the turf.

Compaction and excavation are also critical steps in preparing the base. A compacted base ensures the turf lies flat and prevents uneven settling. Excavation, on the other hand, allows for the removal of debris and uneven terrain.

You'll need to lay wire mesh, such as chicken wire, prior to adding the road base to the surface.

The area will then be compacted to manufacturers' recommendations.

This wire mesh, used in conjunction with the base layer, will provide added security when installing artificial turf.

For slopes up to 15 degrees, this is a recommended approach for a stable installation.

Remember to compact the area to the manufacturers' recommendations for a secure base.

Preparing

Before you start preparing the ground for artificial turf, it's essential to remove the natural grass and 2-3 inches of soil. This will give you a clean slate to work with.

You'll want to apply a heavy layer of weed killer to the surface to prevent any remaining weeds from growing through the new turf. This is especially important if you're installing pet turf, as weeds can harbor pet odors.

To save money, consider using decomposed granite as an alternative to Class II Road Base. It's easier to get ahold of and can be compacted using a push broom and a heavy-duty roller.

If you're installing artificial turf on a slope or hill, you'll need to add some extra steps to ensure the slope is secure and won't cause the synthetic turf to slide and move over time. This may involve laying wire mesh or a geotextile permeable paver to provide added support.

A sandbed of yellow sharp sand can be sufficient for a garden, but the thickness will depend on the local soil conditions. For poorly water-permeable clay soil, you may need a slightly thicker layer.

You'll want to compact and level the sandbed well before installing the artificial turf. This will ensure a solid foundation for your new lawn.

If you're installing artificial turf over concrete, you'll need to chop off any sharp edges to smooth the area and prevent damage to the turf. Heavy professional adhesives may leave stains on the concrete, but securing the turf with glue will prevent wrinkles and movement as the temperature fluctuates.

To create a stable base for artificial grass in an area that will be heavily trafficked or drivable, you can use geotextile permeable pavers to provide additional support. This will help prevent the turf from washing away with rainfall.

A weed barrier is not recommended when prepping the sub-base material for pet turf, but you may want to consider one if you're already battling weeds in the area regularly. This will prevent weeds from poking through the new turf.

Infill is also a good idea for many turf installations, especially if you're looking for a more real grass feel. Pet owners may appreciate the benefits of an infill with a deodorizer to prevent pet odors.

To groom the turf for optimal settling and stability, start by using a power brush with heavy bristles to stand the grass blades upright. Then, apply infill or durafill sand evenly throughout the turf installation.

Skipping the base layer for artificial grass can lead to poor drainage, an uneven surface, weed growth, and poor stability. It's essential to install a solid base to ensure the turf installation performs well and lasts for years to come.

Choosing the Right Materials

You'll want to opt for an artificial grass that is fully permeable and allows water to escape through the backing material for the best drainage results.

There are drainage grids available, such as AirDrain and DrainCore, that can be used to lift the surface and create an air void for ventilation and water flow. In severe cases, french drain systems can be installed.

Place the bender board into the trench, making sure it sits flush with the ground. This will create a clean separation line between the turf areas.

Secure the bender board in place at regular intervals, typically every 4-6 feet, using stakes or anchors. Drive the stakes or anchors through pre-drilled holes in the bender board and into the ground to provide stability.

If your boundary requires multiple lengths of bender board, overlap the ends slightly and use connectors or screws to join them securely. This will ensure a seamless connection between the pieces.

Fill the trench with soil, compacting it gently to provide support for the bender board. Smooth out the soil on both sides of the board to create a clean and smooth transition between the turf areas.

You can install artificial grass directly over concrete as long as the concrete doesn't cause drainage issues. However, it's essential to smooth out any sharp edges to allow for easy gluing.

Heavy traffic or drivable grass areas require a more stable turf base layer, which can be achieved with geotextile permeable pavers. These paver tiles provide additional support to the base.

A hardened subbase is a foundation capable of withstanding heavier loads, achieved through the use of crushed rubble or recycled concrete aggregate (repac). This type of foundation is also employed beneath driveways and roads.

The thickness of the rubble foundation varies between 8 and 15 cm, while the finishing layer ranges from 2 to 4 centimeters. This subbase for artificial turf is applicable when it will be subjected to heavy loads.

A sand-cement or stabilisé foundation is a commonly used foundation for laying artificial turf, particularly in Belgium. The ratio of sand to cement is crucial, as too much cement can make the stabilisé less permeable to water.
