First, let’s go over why you need a base layer. The base layer creates a level platform and provides drainage for artificial turf. When installing a synthetic grass base layer, excavate 3 to 4 inches of topsoil. The best materials for the base layer are 3 inches of class II road base followed by an inch of decomposed granite (also known as granite dust).
You can lay weed barrier fabric under the base layer, over the base layer, or both.
Lay the landscaping fabric under the base layer to prevent contamination and provide a ground stabilization membrane.
If the native soil is hard (as opposed to clay-like), there is no need to install weed barrier fabric under the base material. Simply lay the weed suppressant membrane over the base.
Now that we have shared a few reasons for installing landscape fabric for synthetic turf, it’s time to explain why weed barrier is not right for some artificial grass projects.
When You Have Pets Who Go to the Bathroom Outdoors If you have pets that will use artificial turf as a bathroom, you should be aware that weed barrier fabric will soak up liquid waste and create lasting odors. This is the main reason why some people with artificial turf choose not to install weed barrier.
However, if you have pets and still want to benefit from the protection and stability of weed barrier fabric, you can use a turf deodorizer like ZeoFill infill. ZeoFill infill is made of 100% natural materials and prevents the ammonium in pet urine from turning into a bad-smelling gas.
ZeoFill infill is just one of several pet-friendly options when choosing infill for your artificial turf.
If You Want to Remove Your Artificial Grass in the Future Weed barrier fabric is excellent at preventing soil aeration and stopping weed growth, but this also leads to less healthy soil. This could be a problem if you decide to remove the artificial grass at some point and choose to grow a garden. The ground covered by the weed barrier cloth will not be conducive to thriving plant life, and you will have difficulty growing a garden there.
Wondering why you should invest in a weed barrier? A weed barrier:
1. Blocks Weed Growth
The fabric blocks sunlight from reaching the soil. Weeds need sunlight to grow. Even if a stubborn weed pops its head out of the ground beneath your artificial grass, the weed barrier cloth physically stops the weed from reaching the artificial turf. As its name suggests, it acts as a barrier between the weed and the synthetic turf.
2. Prevents Soil Aeration
When soil is aerated, more oxygen gets into the soil, promoting weed growth. One of the most significant natural sources of soil aeration is the earthworm, eating its way through the soil, loosening it up, and leaving tunnels for water, nutrients, and air to reach weed seeds buried in the dirt.
The more earthworms in your soil, the more likely it is that weeds will be able to grow and thrive. Landscape cloth for synthetic turf is a barrier that will keep the earthworms at bay. They won’t want to live where they can’t reach the surface. With fewer earthworms, weeds will have a more challenging time reaching your turf.
3. Provides Ground Stabilization
You want a solid base for your artificial turf. If there is loose or rocky soil beneath your artificial turf, you could end up with bumps and dips that make it less comfortable to walk on. Weed barrier fabric adds stability, especially if it is a woven weed barrier. It provides an extra layer of firmness and helps prevent soil erosion, so you don’t have to worry about the elements destroying the base of your artificial turf.
4. Protects Synthetic Grass
Besides stabilizing the ground beneath the artificial grass, the weed barrier cloth cushions the artificial turf from whatever is in the soil beneath it. Sharp debris, such as pebbles and rocks, can puncture your artificial grass (if there is no base layer). A layer of weed barrier cloth under your turf adds protection. You want to avoid punctures in your synthetic grass because they can weaken the turf and make it susceptible to more damage.
5. Prevents Base Contamination
Weed barrier can separate the native soil from the base layer (also known as the sub-base layer). If contaminants are in your native soil, you could also get impurities in the base layer unless weed barrier fabric is in place. A weed barrier helps keep the base layer clean.
Weed barrier for artificial grass is a geo-textile fabric that is installed as a synthetic turf underlayment. It is also known as weed barrier cloth, weed block fabric, and landscaping fabric. Weed barrier is typically made from polyester or polypropylene. It comes in woven or non-woven styles.
When you install artificial grass, you may not think you’ll have to deal with weeds. After all, you are covering up the native soil.
Properly installed new or used artificial grass will indeed prevent weeds from growing through the turf’s backing.
However, weeds can still push against the bottom of the artificial turf and disfigure it.
Weeds are uncommonly good at finding ways to grow in unlikely places. Thankfully, there is a solution: use weed barrier fabric to prevent unsightly lumps and bumps in artificial turf projects.
Although we recommend weed barrier in most cases, there are some situations where you should avoid installing it under synthetic turf.
Proper artificial turf maintenance is critical to avoiding damage in the future. Some of the most essential elements of high-quality care are:
Removing dirt, debris, and other pollutants by using water and a turf rake.
Cleaning stains and removing pet waste as soon as possible
Using special cleaning solutions to remove mold and mildew timely
Brushing your turf regularly
Trying to keep extreme heat and sharp objects away from the turf
Used artificial grass is an excellent cost-effective option for your turf needs. With the right approach to maintenance and minor repairs, this durable and beautiful surface can serve you for many years to come.
Low-quality artificial turf installation or damage to the sub-base layer can cause serious issues that can’t be fixed without professional attention. These problems include:
Poor drainage causing mold and mildew.
Debris buildup under the surface causing unevenness, bumps, and pooling water.
Compaction and uneven surfaces affecting the appearance and lifespan of the turf.
Soil erosion (poorly installed artificial turf can’t control soil erosion).
If you encounter serious artificial turf issues, quick DIY fixes won’t help. It’s best to let professionals handle the problem since it may require digging up the synthetic turf to fix the sub-base layer.
Some types of damage could cause your artificial turf to lose color. Meanwhile, some pieces of used synthetic grass may not be perfectly uniform in color. Instead of fixing artificial grass with patches, you can use color-matching turf paint.
Spray-painting discolored or faded blades can give your used grass a fresh new look.
What To Do After Initial Repairs Once you finish minor artificial grass repairs, you need to:
Blend the repair – use a soft-bristled brush or broom to brush the fibers of the repaired area and the surrounding turf together.
Inspect the repair – make sure the repaired area is secure and well-blended.
With the right approach, minor repairs remain invisible and don’t interfere with day-to-day use.
When you purchase used artificial turf, a good rule of thumb is to buy 30% more than you need for fitting irregularly-shaped areas and fixing imperfections. When you have one damaged section, replacing artificial grass isn’t complicated.
Cut away the damaged section using a box cutter
Take a piece of excess turf and cut it to match the removed section
Place the excess on the surface and ensure that turf blades face the same way as the blades on the existing turf.
Secure the turf with 5-inch nails and a hammer
Alternatively, you can secure the new piece the same way you fix artificial turf seams. This involves using a combination of seam tape and turf glue. If you don’t have these materials, nails will do just fine.
