How to Lay Artificial Grass on Concrete Like a Pro [Simple Step-by-Step Guide]

Imagine stepping out onto a lush, green lawn… without the hassle of mowing, watering, or dealing with muddy patches. 

With artificial turf, that vision is a simple reality whether you have a dull patio, a neglected balcony, or a lifeless backyard. Chances are you already know that synthetic turf can transform these areas into inviting, low-maintenance oases.

But can you install artificial grass over existing concrete?

(Spoiler alert: Yes, you can!).

From preparing the concrete surface to choosing the right underlay, this guide will walk you through a smooth and durable installation process step by step. 

You’ll also discover expert tips to enhance drainage, improve comfort underfoot, and maintain your artificial lawn for years to come.

Synthetic grass is a smart landscaping solution that can revitalise dull, hard surfaces like concrete. Whether it’s a backyard, patio, balcony, or even a driveway, synthetic turf can bring life to any space, making it greener, softer, and more inviting.

One of the biggest advantages is its low maintenance. Unlike natural turf, which requires regular mowing, watering, and fertilising, synthetic grass stays lush and vibrant with minimal effort.

This is particularly beneficial in Melbourne, where unpredictable weather is an everyday challenge.

Synthetic turf is also highly durable and designed to withstand heavy foot traffic, UV exposure, and Melbourne’s varying climate conditions. It doesn’t fade, wilt, or develop muddy patches, making it ideal for households with kids and pets.

Plus, with proper installation, it provides excellent drainage, preventing puddles from forming after rainfall.

Modern synthetic lawn is designed with soft, cushioned fibres that feel great underfoot, making it a fantastic option for outdoor play areas, relaxation zones, or even alfresco dining spaces.

With the right underlay, you can create a surface that mimics the natural feel of real grass while offering superior comfort and longevity.

Environmental Impact

Artificial turf is often praised for its water-saving benefits, but it’s important to be mindful of its environmental footprint.

While high-quality synthetic turf is made to last for years, it is still a petroleum-based product, which means its production and disposal can impact the environment.

To make an eco-conscious choice, opt for artificial turf made from recycled materials and ensure it’s recyclable at the end of its lifespan.

Some manufacturers now produce turf with sustainable backing and infill options that reduce heat absorption and improve drainage.

Choosing an underlay made from organic or permeable materials can also help maintain soil health and reduce runoff issues.

Do You Need Permits or Inspections?

In most residential cases, installing an artificial lawn on private property does not require special permits in Melbourne.

However, if the installation involves modifications to drainage systems, shared spaces (such as apartment courtyards), or council-managed areas, you may need approval.

Some homeowners’ associations or body corporations may have regulations regarding the use of synthetic grass, especially for front yards or communal spaces.

Before proceeding, check with your local council or strata management to ensure compliance.

For large-scale installations, such as commercial properties or public areas, specific environmental impact assessments or drainage considerations might be required.

Consulting with a professional installer can help you navigate any necessary approvals and ensure your project meets local guidelines.

Assessing Your Property’s Needs

Every home is different, and understanding your space’s unique requirements will help ensure a successful installation.

How Will You Use the Space?

Consider how you plan to use the area covered with synthetic turf. Is it a play area for kids? A pet-friendly zone? A decorative space for entertaining? The answers will determine the type of turf you need. For example:

• For children’s play areas: Choose soft, cushioned turf with shock-absorbing underlay for safety.
• For pet-friendly spaces: Opt for odour-resistant, easy-to-clean synthetic lawn with good drainage.
• For high-traffic areas: Look for durable turf with strong fibres that can withstand frequent use.

What Are the Drainage Conditions?

Concrete surfaces do not absorb water like soil, so proper drainage is essential. If water pools on your concrete, you may need to install drainage holes or a permeable underlay to prevent issues like mould, mildew, and slippery surfaces.

How Much Turf Do You Need?

Measure your space carefully, accounting for any curves, corners, or fixed structures like garden beds or outdoor furniture. Buying a little extra turf ensures you have enough material for precise cuts and adjustments.

Choosing the Right Synthetic Grass

Not all synthetic turf is created equal, so selecting the right type for your Melbourne home is key.

Pile Height and Density

• Short pile (10–20mm): Ideal for patios and balconies where a sleek, low-maintenance look is preferred.
• Medium pile (25–35mm): A good all-rounder, offering a balance of comfort and durability.
• Long pile (40mm+): Provides a luxurious, natural appearance but may require more maintenance.

Material and UV Resistance

High-quality artificial turf is made from polyethylene or polypropylene and should have UV protection to prevent fading under Melbourne’s harsh sun.

Backing and Drainage

A strong latex or polyurethane backing ensures longevity while perforations improve water drainage. Look for a product with a built-in drainage system if installing in a wet area.

Essential Tools and Materials for Installation

Gathering the right tools will make the installation process smoother and more efficient. Here’s what you’ll need:

Tools for Surface Preparation

• Broom or pressure washer – To clean the concrete thoroughly before installation.
• Concrete sealant (if needed) – To repair cracks and create a smooth base.
• Drill (for drainage holes) – Necessary if your concrete surface has water pooling issues.

Tools for Synthetic Turf Installation

• Utility knife – For precise cutting of the artificial turf.
• Measuring tape and chalk line – To ensure accurate sizing and alignment.
• Adhesive or double-sided tape – To secure the grass edges and prevent movement.
• Trowel or adhesive spreader – For applying glue evenly.
• Seam tape – To join multiple pieces of turf seamlessly.
• Heavy roller or weighted object – To press the turf down for a secure bond.

Synthetic Grass Type

Selecting the right type is the most important decision in the installation process.

Recommended Artificial Grass Types

• Budget-friendly options: If you’re looking for an affordable solution, a short-pile (10–20mm) artificial lawn works well for balconies and decorative areas.
• All-purpose turf: A medium-pile (25–35mm) option is great for high-traffic areas, providing a balance of durability and comfort.
• Luxury, natural-look turf: For a premium look and feel, long-pile (40mm+) synthetic grass provides a lush, soft texture.

Tips for Locally Sourced Quality Artificial Grass

• Check for UV-resistant properties to prevent fading under Melbourne’s strong sunlight.
• Ask about warranty coverage—good quality synthetic turf should have at least an 8- to 10-year warranty.

Underlay

Underlay is a crucial component when laying artificial grass on concrete, as it improves drainage, adds cushioning, and prevents a hard surface feel.

Recommended Underlay Types

• Shockpad underlay – Ideal for play areas or pet-friendly spaces, providing extra cushioning and safety.
• Permeable rubber underlay – A great choice for drainage, ensuring water doesn’t pool underneath the turf.

Tips for Sourcing Quality Underlay

• Look for drainage-friendly materials that allow water to pass through, reducing the risk of mould.
• If you’re installing a pet-friendly lawn, opt for an odour-neutralising underlay to help with hygiene.

Adhesives and Joining Materials

Securing your synthetic lawn properly prevents movement and ensures a seamless look.

Recommended Adhesives and Tapes

• High-bond turf adhesive – Choose a weather-resistant, flexible adhesive.
• Double-sided turf tape – Perfect for smaller installations, it provides a secure grip without the need for glue.
• Seam tape – Required for joining multiple turf pieces together.

Adding Stability and Realism

Infill materials help the turf maintain its shape, provide a more natural feel, and improve durability.

Recommended Infill Types

• Silica sand infill – Provides a realistic weight and keeps fibres upright.
• Rubber crumb infill – A softer option, often used for play areas and sports surfaces.

Tips for Sourcing Quality Infill

• If opting for sand, ensure it is non-toxic and silica-free to avoid dust issues.
• For pet areas, look for antibacterial infill to reduce odours.

Step #1 – Prepare the Concrete Surface

Before laying artificial grass, the concrete must be clean, dry, and level to ensure proper adhesion.

Clean the Surface

• Use a broom, pressure washer, or hose to remove dirt, dust, and debris.
• Scrub off any oil stains or algae using a degreaser or vinegar solution.
• Allow the concrete to fully dry before moving on.

Repair Any Cracks or Uneven Areas

• Fill cracks and holes with concrete filler or self-levelling compound.
• If the surface is uneven, use a grinder or sander to smooth it out.
• Let the repairs cure for 24 hours before proceeding.

Step #2 – Ensure Proper Drainage

Concrete does not naturally drain water, so ensuring proper drainage is key to preventing puddles and mould.

Check for Water Pooling

• Pour a bucket of water over the concrete and observe if it pools in any areas.
• If water collects, drill small drainage holes (8–10mm wide) every 50cm to allow for runoff.

Apply a Permeable Underlay (Optional but Recommended)

• Lay shockpad underlay or drainage tiles to improve water flow and comfort.
• Secure it to the concrete using outdoor double-sided tape or adhesive.

Step #3 – Cut and Position the Artificial Grass

Measure and Roll Out the Turf

• Measure the area precisely, leaving an extra 5–10cm on each edge for adjustments.
• Unroll the artificial turf and let it acclimate for a few hours to prevent wrinkles.

Trim the Grass for a Perfect Fit

• Use a sharp utility knife to cut along the edges, following the contours of your space.
• Ensure the grass blades are facing the same direction for a uniform look.

Step #4 – Secure the Artificial Grass in Place

Apply Adhesive or Tape

• Use outdoor-grade artificial lawn adhesive along the perimeter and any joins.
• Alternatively, apply double-sided tape if you prefer a non-permanent option.
• Press the turf down firmly, ensuring full contact with the surface.

Seam Multiple Grass Pieces Together

• If using multiple turf sections, place seam tape underneath the joint.
• Apply adhesive on the tape and press both edges down tightly together.
• Brush up the grass fibres to conceal the seam.

Step #5 – Add Infill and Final Touches

Spread the Infill

• Use silica sand or rubber infill to add weight and improve the turf’s appearance.
• Spread the infill evenly using a stiff broom.

Brush and Settle the Grass

• Brush the synthetic grass against the grain to lift the fibres.
• Walk over the area or use a garden roller to ensure a firm bond.

When to Call a Professional

While DIY installation is manageable for small spaces, consider hiring a professional if:

• You have a large or complex area requiring multiple seams and cuts.
• Your concrete surface is heavily cracked and needs resurfacing.
• You need custom drainage solutions for high-moisture areas.
• You want a warranty-backed installation for long-term durability.
