Installing artificial turf can completely transform a backyard, commercial landscape, or recreational space. But a synthetic grass install isn’t just about rolling out turf and securing it in place. Proper preparation, drainage, and installation techniques determine whether your lawn looks great for 10+ years or starts showing problems within months.
In short: most synthetic grass failures happen because of poor installation practices.
For homeowners and property managers across NSW, understanding the most common mistakes can save thousands of dollars in repairs or replacements.
At East Coast Synthetics, we’ve seen many DIY installations and poorly installed jobs that required full corrections. Based on years of experience installing artificial lawns across Australia, here are the top mistakes to avoid during a synthetic grass install.
Poor Ground Preparation
The most common issue in any synthetic grass install is insufficient ground preparation.
Artificial turf requires a stable base layer. Without it, the surface can become uneven, sink in areas, or develop drainage problems over time.
Professional installers typically follow a structured base preparation process:
- Remove existing grass and organic material
- Excavate the soil to the correct depth
- Install a compacted crushed rock base
- Apply a bedding layer for smooth turf placement
- Ensure proper drainage grading
Skipping these steps often leads to:
- Uneven surfaces
- Turf wrinkles or movement
- Poor drainage after rain
- Premature wear
In NSW’s varied climate, from coastal rainfall to hot summers, a well-prepared base is essential for durability.
For professional installations designed to last, it’s best to work with specialists experienced in synthetic grass systems and preparation methods. East Coast Synthetics provides expert synthetic grass installation services tailored for residential and commercial properties across NSW.
Ignoring Drainage Requirements
Many people assume artificial grass naturally drains well. While quality turf products are designed with drainage holes, the base system underneath is what truly controls water flow.
If the sub-base isn’t graded correctly, water can pool under the turf and cause:
- Odours
- Bacterial growth
- Turf movement
- Mud build-up under seams
Professional installers typically grade the base slightly away from structures to allow efficient water runoff.
This is particularly important in areas across NSW where heavy rain events are common.
A properly installed drainage base ensures your synthetic lawn remains clean, dry, and low-maintenance year-round.
Choosing the Wrong Turf for the Area
Another major mistake during a synthetic grass install is selecting the wrong type of artificial turf for the intended use.
Not all synthetic grass products are designed for the same purpose. Some are made specifically for residential lawns, while others are engineered for high-traffic areas, playgrounds, pet zones, or commercial landscaping.
Choosing the wrong turf can lead to premature wear, flattening, or an unnatural appearance.
Here are a few key factors professionals consider when selecting turf:
- Pile height – Shorter turf works better for high-traffic areas
- Density – Denser turf provides a more natural look and durability
- Backing quality – Strong backing improves longevity and drainage
- UV protection – Essential for Australian climates with strong sun exposure
For example, a soft landscaping turf designed for decorative lawns may not perform well in areas with constant foot traffic or pets.
Experienced installers help match the right turf product to the space, ensuring the lawn performs well long term.

Incorrect Seaming and Turf Joining
Joining multiple pieces of artificial grass together is one of the most technical parts of a synthetic grass install.
When seams are poorly installed, they become highly visible and can separate over time. This not only affects the appearance of the lawn but can also create tripping hazards.
Common seaming mistakes include:
- Misaligned grass fibres
- Inconsistent seam spacing
- Poor adhesive application
- Improper seam tape installation
A professional installer ensures the grain direction of the turf matches across all sections, making seams nearly invisible.
They also use specialised seam tape and adhesive systems designed specifically for artificial turf installations.
Proper seam work ensures:
- A natural, seamless lawn appearance
- Strong long-term bonding
- Reduced risk of lifting edges
This level of precision is one of the biggest differences between a DIY installation and a professional synthetic grass install.
Forgetting About Edge Restraints
Edge restraints are another often-overlooked component during artificial turf installation.
Without proper edging, the turf can shift over time, particularly in areas exposed to:
- Foot traffic
- Pets
- Soil movement
- Weather changes
Professional installers typically secure turf using edging systems such as:
- Aluminium edging
- Treated timber borders
- Concrete edges
- Hidden fixing systems
These restraints keep the turf locked in place, maintaining a clean and defined lawn edge.
A secure perimeter also helps prevent base erosion and turf lifting, which can significantly shorten the lifespan of the installation.
Skipping Weed Barrier Installation
One of the most overlooked steps in a synthetic grass install is installing a proper weed barrier.
While artificial turf blocks most sunlight, weeds can still grow through the base layer or appear along the edges if preventative measures aren’t taken.
Without a weed membrane, you may eventually see:
- Small weeds pushing through seams
- Growth around edges or borders
- Increased long-term maintenance
A commercial-grade weed barrier fabric is typically installed between the soil and the base material. This layer helps prevent weed growth while still allowing water to drain properly.
Professional installers ensure the barrier is:
- Correctly overlapped
- Secured in place
- Installed before the base layer is compacted
This simple step can significantly extend the lifespan and appearance of your artificial lawn.
Poor Turf Infill Application
Infill plays an important role in maintaining the structure and performance of artificial turf. Unfortunately, many DIY installers either skip it entirely or apply it incorrectly.
Infill helps:
- Keep grass fibres standing upright
- Add weight to stabilise the turf
- Improve durability in high-traffic areas
- Enhance drainage and cooling
Without the right amount of infill, turf can quickly look flat or worn.
Common mistakes include:
- Uneven infill distribution
- Using the wrong type of infill material
- Applying too little infill
- Failing to brush the fibres after installation
Professional installers carefully spread and brush infill into the turf fibres using specialised equipment. This ensures the lawn maintains a natural look and feel for many years.
Why Professional Installation Matters
Avoiding these mistakes can make the difference between a lawn that lasts 15 years or more and one that needs repairs within a few seasons.
A professional synthetic grass install ensures:
- Proper base preparation
- Correct drainage design
- High-quality turf selection
- Seamless joining techniques
- Long-term durability
