Artificial grass has become an increasingly popular alternative to natural grass lawns in backyards and landscapes across New Zealand. The primary benefit of artificial turf is its low maintenance requirement compared to real grass. Artificial grass does not need regular mowing, watering, or fertilizing. This makes artificial lawns a practical and convenient solution for many homeowners.
Installing artificial grass directly over a concrete surface is one way to create a lush green lawn without the need for an extensive lawn substrate. Laying synthetic turf over concrete can work well in certain situations. However, there are also some important considerations when it comes to proper installation and ensuring decent drainage.
This guide will provide an overview of the pros and cons, installation process, and key steps involved in laying artificial grass on concrete in New Zealand. We'll cover whether it's advisable, how to prepare the concrete surface, artificial turf options, drainage considerations, and maintenance requirements. Read on to learn more about creating an artificial lawn directly over concrete.
Artificial grass offers a number of advantages when installed on a concrete surface:
Low Maintenance: Once artificial turf is installed, it requires very little ongoing care and maintenance. There is no need for regular mowing, watering, fertilizing or treatment with weed killers and pesticides like natural grass requires. The synthetic blades of artificial grass retain their fresh, green appearance without any effort.
No Watering Required: Since artificial turf does not grow, it does not need any watering. This makes it ideal for homes and businesses looking to conserve water usage. Installing artificial grass on concrete removes the need for irrigation systems.
Saves Time: Maintaining a beautiful lawn can be very time consuming, with tasks like mowing, edging and weeding taking up many hours each week in summer. Laying artificial grass on concrete provides a perfect, lush lawn without any of the hard work.
Always Green & Lush: Artificial grass maintains its vibrant color and thickness at all times, regardless of weather conditions. It does not turn brown or dormant during dry spells like real grass can. The synthetic materials are unaffected by changing seasons.
Durable & Long-Lasting: Quality artificial turf is extremely durable when laid on a hard surface like concrete. With proper installation, artificial grass can last up to 25 years with minimal fading. It stands up well to foot traffic without getting worn down.
While artificial grass offers a low maintenance alternative to real grass, installing it on concrete does come with some potential drawbacks to consider:
Doesn't absorb rainwater, requires drainage - One of the biggest cons is that concrete and artificial grass will not absorb any rain or irrigation water. This means water will simply pool on top of the surface if proper drainage is not installed. Pooled water can lead to mildew, mold, and bacteria growth in the grass over time. A proper drainage system needs to be installed, such as having the concrete graded to drain away from the house or installing a drainage mat underneath the turf.
Hard surface is less forgiving for kids and pets - Artificial grass on concrete provides a less forgiving surface for kids or pets than installing it over soil. Falls and tumbles hurt more when landing on hard concrete versus natural ground. This may require extra safety precautions.
Hot surface temperature - Concrete absorbs heat from the sun and can get incredibly hot during summer months. The artificial grass will do little to reduce this heat. This can lead to burned paws on pets or uncomfortably hot temperatures for kids playing. Providing shaded areas may help mitigate this issue.
Can highlight imperfections - Any imperfections, cracks, stains, or unevenness in the concrete will likely show through the artificial grass. The concrete needs to be as smooth and flawless as possible before installing turf. Any repairs or patching should be done beforehand.
Glue odor - Adhesives are typically used to glue the artificial turf to concrete. This glue will have a strong odor for several days as it off-gasses VOCs. Keeping windows open or using fans can help ventilate while the odor dissipates. Those sensitive to chemical smells may want to avoid this.
Yes, it is absolutely possible to install artificial grass on a concrete surface, however there are some important preparations and considerations to ensure it is done properly.
The key is making sure the concrete has the appropriate surface texture and slope for drainage, and securing the artificial turf adequately so it stays in place. Providing enough of a base layer between the concrete and grass is also important for cushioning and drainage.
With proper subsurface work, synthetic grass can be successfully installed onto existing concrete. The artificial turf fibers are able to withstand direct contact with the concrete. Just like with dirt or gravel bases, a cushioned underlayment placed below the artificial grass on concrete is recommended for additional comfort and safety.
The concrete needs to be clean, level, and porous enough to allow rainwater to drain through the turf backing and underlayment. If the concrete has a broom finish and is pitched away from buildings, it should work fine for laying fake grass. Any cracks or uneven areas in the slab should be patched and leveled first.
As long as the concrete foundation is flat, stable and drains well, it is possible to add beautiful, lush artificial grass on top that looks and feels like natural lawn. With the right materials and proper installation, synthetic turf performs well on concrete surfaces. The grass blades effectively disguise the hard surface underneath while providing an attractive, low maintenance alternative to real grass.
Before installing artificial grass on concrete, the surface needs to be properly prepared. Here are the key steps:
The concrete should be thoroughly cleaned to remove any dirt, debris, oil or grease that could prevent the artificial grass from adhering properly. Use a stiff brush and concrete degreaser to scrub the surface clean. Power wash if needed. Ensure the concrete is completely dry before moving to the next steps.
The concrete surface should be as smooth and level as possible. Use a long straightedge to check for any high or low spots, bumps, or cracks that need to be filled in. For minor imperfections, you can use a floor leveling compound. Larger uneven areas may need to be resurfaced with new concrete. Proper drainage is important, so ideally the surface should have a very slight slope.
While some artificial grass products can be installed directly on concrete, it is often recommended to add a sub-base layer like crushed gravel first. This helps provide some cushioning, allows for drainage, and protects against concrete moisture. Spread the gravel in a 1-2 inch layer, compacting it down with a plate compactor. Then add your chosen weed barrier fabric over the gravel before installing the artificial turf.
Following these important preparation steps will provide the proper foundation needed for a successful artificial grass installation on concrete that will last for many years. The concrete surface needs to be clean, smooth, and level, and ideally have a sub-base layer added before installing the turf.
Laying artificial grass directly onto a concrete surface requires careful preparation and installation to ensure proper drainage and a natural looking lawn. Here are the key steps:
Clean the concrete thoroughly to remove any dirt, debris or loose material. Ensure the surface is completely dry before installation.
Apply a layer of weed barrier fabric over the concrete. This helps prevent weeds from growing up through the artificial turf. Staple the fabric securely in place.
Spread a thin layer of coarse sand over the weed barrier, around 1cm deep. This helps provide a more natural texture and some drainage under the turf. Rake the sand smooth.
Unroll the artificial grass and cut it to fit the area, leaving an extra 5-10cm around the edges. It's easier to cut the turf before gluing it in place.
Apply a turf adhesive to the concrete surface using a notched trowel. Use an adhesive suitable for bonding artificial grass to concrete.
Carefully lay the turf into the adhesive, pressing down firmly to secure it in place and eliminate any air bubbles. Work section by section.
Allow proper curing time for the adhesive before continuing with installation. This may take 24 hours.
Trim the excess grass around the edges with a sharp utility knife.
Use adhesive and seam tape to join different sections of turf to form one continuous lawn. Roll the seam to bond it.
Spread silica sand into the turf fibers and brush gently to fill the pile. This helps support the blades in an upright position.
Once the adhesive has fully cured, water the grass to rinse away any excess sand. Your artificial lawn on concrete is now complete.
Drainage is an important consideration when installing artificial grass on concrete. Without proper drainage, water can pool under the artificial turf leading to bad odours, mould growth and other issues. There are a few ways to allow drainage when laying artificial grass on concrete in New Zealand:
Use an artificial turf product that has a permeable backing. Many modern artificial grass products are made with perforated backings that allow water to drain vertically down through the turf. The holes in the backing prevent water from pooling underneath.
Create drainage holes directly in the concrete. Using a masonry drill bit, you can make holes spaced throughout the concrete to give water escape points. The holes should be angled slightly to facilitate drainage. Place them every 30cm or so.
Install a runoff tray system. For this you'll need to frame the concrete area with timbers. Place the timbers around the perimeter with a 2-3cm gap between the wood and the concrete. Then use plastic trays made for artificial grass drainage to bridge the gap around the entire edge. The trays have small slits that allow water to drain out. You can also install a drain pipe in the tray system to move water away from the area.
Proper drainage under artificial grass on concrete is crucial for performance and longevity. Using one of these methods will prevent surface pooling, odours and mould growth. Check with the turf manufacturer for their recommendations to integrate drainage into your unique concrete installation. With the right preparation, artificial grass can be successfully installed on concrete areas to provide a lush lawn look.
When installing artificial grass on a concrete surface, it's important to include some type of edging to create a border around the artificial lawn. There are several edging options to consider:
Concrete Curbing
One of the most popular edging choices is to install concrete curbing around the perimeter of the artificial grass area. Concrete curbing provides a sturdy border that delineates where the grass begins and ends. The curbing should be installed so that it is flush with the edges of the concrete slab. This helps prevent the artificial grass edges from peeling up over time. Concrete curbing comes in various shapes and colors to match the look you want to achieve.
Timber Edging
Timber makes for an attractive edging option. Pressure treated pine is a suitable timber for edging artificial grass. The timber boards should be secured into the concrete using masonry anchors. Leave a small gap between the boards to allow water to drain off the artificial lawn. Timber edging gives a natural look and is relatively low maintenance. Over time, the timber will weather to a silver-grey color.
Metal Edging
Aluminum and galvanized steel are common metals used to edge artificial grass. Metal lawn edging provides a clean, modern look. Like the timber edging, metal edging should be anchored into the concrete perimeter. Metal edging is very durable, though over time it can potentially rust. Look for rust-resistant metals or coatings when selecting a metal lawn edging product.
The edging for your artificial grass on concrete provides both form and function. Consider the look you want to achieve along with practical factors like budget and maintenance. Proper installation of high quality edging can help your artificial lawn last for many years.
Cutting artificial grass around fixed objects like trees, fence posts, and walls takes some precision but is doable with the right tools. Here are some tips:
Use a sharp utility knife to cut the artificial turf. Make sure the blade is new so it creates clean cuts.
For straight lines, use a chalk line to create a cutting guide. Snap the chalk line around the object, then follow it with the utility knife.
Around tree trunks, cut a circle slightly larger than the trunk to allow space for growth. Cut from the edge of the turf towards the tree trunk.
For fence posts, cut two straight lines from the edge to the post. Then cut out a wedge shape at the post to allow the turf to fit flush.
Where the grass meets a wall, cut a straight line following the wall edge. Use a divider to maintain an even gap between the wall and grass.
Make relief cuts at corners and posts to allow the turf to bend and lie flat. The relief cuts should extend about 2/3 into the turf backing.
After cutting, use a roller to press the seams together for a tight fit. Apply turf adhesive along the seams for added stability.
Use a utility knife to trim any excess turf around the objects for a tailored, polished look.
With some careful measuring and cutting, you can install artificial grass right up to fixed objects for a seamless finish. Just take it slow and make relief cuts where needed.
Proper maintenance is crucial for keeping your artificial grass looking good and lasting a long time, even when installed over concrete. Here are some tips:
Regular Clearing
Remove leaves, branches or other debris at least once a week. This prevents materials from settling into the grass fibers and decomposing. Use a stiff brush or broom to lightly brush the grass.
Rake the blades upwards with a plastic rake to maintain their upright position. This improves drainage too.
Deep Cleaning
Every 2-3 months, use a bit of mild detergent and water to deep clean the artificial grass. Use a brush or broom to scrub the detergent into the grass.
Rinse the grass thoroughly to remove all detergent residue. You may need to weigh down the corners while rinsing to prevent the grass from lifting.
Allow the grass to dry fully in sunlight before using again. The sunlight helps further sanitize the grass.
Spot Cleaning
For spills and stains, spot clean the area immediately with a mixture of warm water and vinegar. The vinegar disinfects and removes odors.
You can also spot treat pet urine stains with an enzymatic cleaner designed specifically for artificial grass. Rinse and allow to dry fully afterwards.
Loose Seams
Check for loose seams or tears along the edges. Re-adhere any lifted edges with liquid seam sealer.
For minor tears, melt the fibers back together with a soldering iron on the synthetic setting. Larger tears may need patch repair.
Fluffing
Following these maintenance tips will help keep your artificial grass looking great on your concrete area for many years. Let me know if you would like me to expand on any part of the artificial grass care and maintenance process.
The installation of artificial grass on a concrete surface in New Zealand depends on several factors but we would not focus on the specific costs in this section:
Size of the Area: The size of the surface area to be covered forms one of the most significant factors. The larger the space, the more artificial grass will be needed, which naturally, might influence the entire project.
Material Costs: Beyond the grass itself, installing artificial grass also requires some additional materials e.g., underlayment, adhesive for seams, nails or screws, edging materials, and sometimes, specific drainage solutions. These tend to contribute to the overall costs.
Labour: Should you choose to hire a professional installer as opposed to DIY, the labour costs will form part of the total costs. Professional installers not only bring their expertise to the job, but also speed, allowing the project to potentially be completed in less time.
Site Preparation: The condition of the concrete surface and any required preparatory work are important factors. If the surface needs leveling, repair, or any other form of preparation, it would involve extra labour and possibly equipment rentals, thereby impacting the project.
Overall, the total cost of installing artificial grass on a concrete surface is guided by these factors. For a more detailed estimation, consider speaking with a professional installer or a landscape advisor. They can provide you with a comprehensive analysis based on your project details and the conditions of your surface.
There are several alternatives to consider if you don't want to install artificial grass directly on concrete in New Zealand. Here are some of the most popular options:
Spreading gravel over a concrete surface is one option. Gravel comes in various sizes and colors, providing design flexibility. It's also an affordable solution that allows rainwater drainage. However, gravel can scatter outside the boundaries and requires occasional raking to maintain its appearance. It may not provide the same softness underfoot as artificial grass.
Installing concrete pavers on pedestals creates a raised surface over concrete with drainage gaps between the pavers. This provides a hard surface with better traction than artificial grass when wet. Pavers come in numerous shapes, colors and textures to suit different design tastes. But they can crack over time and require more maintenance than artificial turf.
Poured rubber creates a seamless rubberized surface over concrete for children's play areas or paths for example. It provides safety, cushioning and is durable in outdoor areas. Poured rubber is available in various colors and can have graphics embedded. However it's a more expensive option than artificial grass and requires professional installation. The surface can also become hot in direct sunlight.
Can I install artificial grass directly on concrete?
Yes, it is possible to install artificial grass directly onto a concrete surface. However, the concrete will need to be properly prepared first by cleaning and roughening the surface to ensure the adhesive bonds properly.
How do I prepare concrete for artificial grass?
To prepare concrete for artificial grass, first sweep and pressure wash the surface to remove any dirt or debris. Once dry, sand or etched the surface using an etching solution to rough up the smooth concrete and allow the adhesive to bond. Ensure the concrete is flat, with no large cracks or holes. Fill any small cracks with patching compound.
What kind of base do I need under the artificial grass?
No additional base is required when installing artificial grass directly onto concrete. The concrete surface itself acts as the base. Just ensure it is cleaned, etched, level, and free of cracks before installation.
Can I install artificial grass on existing concrete pavers?
Installing artificial grass on existing concrete pavers is possible, but can be more challenging. The pavers must be solid, level, and have tight seams to prevent shifting. Using a flexible polyurethane binder between the pavers can help stabilize them before installing the turf.
How is artificial grass on concrete drained?
Drainage is important for artificial grass on any surface. On concrete, small holes can be drilled into the concrete before installing the turf to allow water drainage. Using a porous backing on the artificial grass can also improve drainage. Installing a slight slope for runoff is recommended.
What type of artificial grass is best on concrete?
Look for artificial grass designed specifically for use on hard surfaces like concrete. Turf with a porous or perforated backing will drain better. t's recommended to opt for a shorter pile height, ideally around 1.27 centimeters to reduce matting and impressions. The blades should be soft for comfort, yet durable.
