Planning and Choosing Your Materials
Before you pick up a shovel, you need to choose the right type of turf for your specific needs. Not all synthetic grass is created equal, and the pile height and density will dictate how the lawn feels underfoot.
For high-traffic areas where kids or pets play, I recommend a shorter, denser pile that can withstand heavy use. If you are looking for a purely aesthetic, lush look for a front garden, a longer, softer blade might be the way to go.
Don’t forget to measure your space accurately, adding about 10% extra for cutting and waste. It is much better to have a little left over than to find yourself a few inches short in a corner.
Essential Tools for the Job
To do this right, you will need more than just a standard garden trowel. Having the correct tools makes the physical work much easier and ensures a professional-grade result.
- A turf cutter (you can hire one of these to save your back).
- A sharp utility knife with plenty of spare blades.
- A heavy-duty vibrating plate compactor (often called a “wacker plate”).
- A wheelbarrow and a sturdy shovel.
- Joining tape and specialized outdoor adhesive.
- Galvanized u-pins or landscape staples.
- A stiff broom or a power brush.
The Importance of a Solid Sub-Base
The secret to a lawn that doesn’t sag or puddle lies beneath the surface. You cannot simply lay turf over existing grass or soil, as the organic matter will rot and cause the ground to shift.
You will need a combination of MOT Type 1 crushed stone for stability and a finer layer of granite dust or sharp sand for leveling. This combination allows for excellent drainage while providing a firm foundation.
Excavation and Ground Preparation
Now comes the hard work! You need to remove the existing sod to a depth of roughly 75mm to 100mm. This creates enough space for your sub-base layers without the new lawn sitting too high above your paving or edging.
While digging, keep an eye out for any large stones or tree roots that might cause bumps later. If you encounter drainage issues in your soil, this is the perfect time to install a simple soakaway or additional drainage pipes.
Once the area is clear, treat the ground with a weed killer to prevent any stubborn growth from pushing through your new installation. It is a small step that saves a lot of heartache later on.
Laying the Geotextile Membrane
After you have excavated the area, I always recommend laying a high-quality weed membrane. This acts as a barrier, preventing weeds from growing up through the drainage holes of your turf.
Ensure the membrane covers the entire area and overlaps at the seams by at least 100mm. Secure it with a few pins to keep it from shifting while you pour your stone base.
Compacting the Base Layers
Pour your MOT Type 1 crushed stone into the area, aiming for a depth of about 50mm to 70mm. Use your plate compactor to firm this down until it is rock solid.
Next, add your layer of sharp sand or granite dust. This “screed” layer should be about 20mm to 25mm thick. Use a long, straight piece of timber to level it out across the entire surface.
Run the compactor over this final layer as well. The goal is a surface that is perfectly smooth but has a slight fall to allow rainwater to run off toward your drainage points.
how do you lay artificial grass: A Step-by-Step Guide
Once your base is prepared, it is time for the most exciting part: rolling out the green! When considering how do you lay artificial grass, the most important rule is to check the “pile direction.”
Artificial grass has a natural lean to the blades. For the best look, you want the pile to lean toward the house or the main viewing area. This makes the grass look much more realistic and vibrant.
- Unroll your turf and let it sit for at least 2 to 4 hours (or overnight if possible) to allow any creases to drop out.
- Position the grass carefully, ensuring it covers all edges with a little bit of overhang.
- Once you are happy with the position, use your sharp utility knife to trim the edges.
- Always cut from the back of the grass (the latex backing) to avoid slicing through the green blades themselves.
- Take your time with the trimming; small, incremental cuts are better than one large mistake.
Perfecting the Joins
If your garden is wider than the roll of grass, you will need to join two pieces together. This is where many beginners get nervous, but don’t worry—it’s easier than it looks!
Ensure the two pieces are laid with the pile running in the same direction. Trim the factory edges off both pieces, usually cutting two or three “ribs” in to ensure a clean stitch line.
Place your joining tape (shiny side down) under the seam. Apply your turf adhesive in a zigzag pattern along the tape, then carefully fold the two pieces of grass onto the glue. Imagine you are zipping up a jacket; you want the blades to meet but not overlap.
Securing the Perimeter
With the joins done, you need to make sure the lawn doesn’t move. Use your galvanized u-pins every 20cm to 30cm around the edges.
When hammering them in, make sure you pull the grass blades apart so the pin doesn’t trap them underneath. If done correctly, the pins will be completely invisible once the grass is brushed up.
If you are laying onto a hard surface like concrete, you would use adhesive around the entire perimeter instead of pins. Just make sure the surface is dry and clean before you start.
Finishing Touches and Infill
Your lawn might look a little flat right after unrolling it. To bring it to life, you need to add an infill, usually kiln-dried sand. This sand serves three vital purposes.
First, it adds weight to the carpet, keeping it flat and preventing ripples. Second, it protects the base of the grass fibers, helping them stand upright. Third, it helps to keep the lawn cool during those rare hot summer days.
Spread the sand evenly across the surface using a seed spreader or by hand. You typically need about 5kg to 8kg of sand per square meter, depending on the pile height of your turf.
Brushing for a Natural Look
Once the sand is down, use a stiff-bristled broom to brush against the pile. This pushes the sand down to the bottom and coaxes the blades to stand up straight.
I find that a power brush is a fantastic investment if you have a large area, as it does the work in a fraction of the time. However, a bit of “elbow grease” with a manual broom works just fine for smaller gardens.
After the first brush, you might notice some areas need a little more sand. Go ahead and touch those up until the surface looks uniform and lush.
Maintaining Your Synthetic Lawn
One of the best things about this project is the lack of maintenance. However, “low maintenance” does not mean “no maintenance.” To keep your lawn looking its best, you should follow a few simple steps.
Remove leaves and organic debris regularly using a leaf blower or a plastic rake. If left to rot, these can turn into compost and allow weeds to grow on top of your grass.
If you have pets, simply hose down the areas they use frequently to prevent odors. For stubborn spots, a mixture of warm water and mild detergent (or a specialized artificial grass cleaner) works wonders.
Dealing with Heavy Furniture
You can certainly put garden furniture or a trampoline on your new lawn. Just be aware that heavy objects will flatten the pile over time.
Every few months, move the furniture slightly and give the grass a vigorous brush to bring the fibers back to life. Avoid using metal-legged chairs that might have sharp edges, as these could potentially puncture the backing.
Also, keep any heat sources like BBQs or fire pits well away from the grass. Synthetic turf is made of plastic, and it will melt if exposed to high heat or stray embers.
Frequently Asked Questions About how do you lay artificial grass
Does artificial grass drain well when it rains?
Yes, absolutely! Quality artificial grass has a perforated backing that allows water to flow through. As long as you have prepared a porous sub-base of crushed stone and sand, the water will drain away just as well as, if not better than, real grass.
How do you lay artificial grass on top of existing concrete?
You can certainly lay it on concrete, provided the surface is flat and has a slight slope for drainage. You will need to use a shock pad underlay to provide cushioning and then secure the edges with a strong outdoor adhesive rather than pins.
Is artificial grass safe for dogs and cats?
It is very pet-friendly! Most modern turfs are non-toxic and very durable. It eliminates the problem of “yellow spots” from pet urine and keeps your house free of muddy paw prints. Just ensure you use a permeable infill to help with odor control.
How long will my new lawn last?
When installed correctly, a high-quality artificial lawn can last anywhere from 12 to 20 years. The lifespan depends on the quality of the product, the amount of foot traffic it receives, and how well you keep up with basic cleaning and brushing.
Can I install artificial grass on a slope?
A frequent query is how do you lay artificial grass around trees or on steep slopes. You can indeed install it on an incline, but you must ensure the sub-base is extra compacted and use more pins at the top of the slope to prevent the turf from “creeping” downward over time.
Conclusion
Transitioning to a synthetic lawn is one of the most rewarding DIY projects a gardener can undertake. It provides a clean, green space that looks immaculate regardless of the weather or the season.
By following these steps—focusing on a solid foundation, choosing the right pile direction, and finishing with a proper sand infill—you will create a professional-looking garden that is the envy of the neighborhood.
Now that you have mastered the basics of how do you lay artificial grass, it’s time to put down the mower and pick up the brush. Go forth and create the beautiful, low-maintenance sanctuary you deserve!
