Why It Is Important To Install Artificial Grass in Rotherham With a 2 x Layer Weed Membrane System
There are many things to consider when installing Artificial Grass in Rotherham. And while grass
quality will play a vital role in the overall appearance of your new synthetic lawn, it is ground
preparation and using the correct weed membrane system that will make all the difference when it
comes to longevity and weather performance.
In this complete guide to installation, we’ll explain why it is so important to install artificial grass with
a two-layer weed membrane system and provide you with our top tips on how to achieve a
The Importance of Weed Membrane For Artificial Grass
When calculating artificial grass cost, you should factor in the additional expenses of weed
membrane and installation essentials such as joint tape, joint adhesive, and securing U-pins. Without
these items, you will not achieve the professional look that you are going for, and your synthetic
lawn will not last.
Some fake grass retailers may suggest that you don’t need weed membrane, but it is essential when
installing a synthetic lawn. Even if you pre-treat your ground soil with weed killer, it is highly likely
that some seeds will be left behind. These seeds could sprout after the first heavy rain, causing an
uneven surface, and ruining the appearance of your artificial lawn.
At Artificial Super Grass, we use heavy-duty 70gsm weed membrane to prevent weeds growing up
through the sub-base and the final layer of artificial grass. When installing, we overlap all joints by at
least 200mm (8 inches) to restrict sprouting, so when doing it yourself, you should purchase more
weed membrane than the astroturf you are fitting. An additional 10% should be sufficient.
In addition to preventing weed growth, weed membrane prevents the sub-base layer mixing with
the underlying soil, which can lead to shifting and settlement and cause irregularities in your
artificial lawn. Think of it like laying the foundations for a new house. It prevents weed growth, stops
the sub-base layer from spreading, and creates a smooth, balanced platform to apply your new turf.
It’s an investment that can help avoid serious issues down the line.
So Why Two Layers?
We recommend fitting two layers of weed membrane, one under the sub-base and a second above
the sub-base before installing the artificial grass. By doing this, you’ll never have to worry about
weeds popping up through your synthetic lawn, and you will have excellent foundations for
drainage. You could save money by fitting just one layer, but it could end up costing you more in the
long run. We firmly believe that superior artificial grass is an investment for family homes,
commercial spaces, and business premises, and so it makes sense to install it properly.
How To Install Artificial Grass
Artificial grass is a versatile landscaping material that you can install on almost any surface including,
concrete and wooden decking, with most installations on ground soil using the correct sub-base. Different
surfaces require different ground preparation methods, but they all need an effective weed
membrane system to prevent weeds from penetrating the sub-base material and ruining the
appearance of your artificial lawn.
Artificial Super Grass has devised an innovative six-stage installation plan that guarantees perfect
results every time. If you would like to have a go at fitting imitation grass yourself, the following
steps will help you achieve your landscaping goals:
Step 1: Excavation
If you are replacing your existing lawn with artificial grass, the first thing you need to do is remove
the natural turf and any paving so that you have clean foundations. Excavation is a messy job, and if
you don’t have access to professional tools, you need to take extra care not to damage the surface
below. As a guideline, you need to excavate approximately 75mm (3") below any path, paving or required artificial grass finish height
to achieve the perfect finish.
Step 2: Weed Membrane Layer 1
With your ground surface prepared, the next stage is to apply the first layer of weed membrane. This
initial covering will stop deep soil weeds from growing, create a protective barrier against worms
and other insects, and it will ensure that the sub-base drains correctly. Apply it as you would any
landscaping fabric, but be sure to overlap any joints by at least 20cm to create an impenetrable layer.
Step 3: Sub-Base Creation
Artificial grass requires a sub-base, and while different companies recommend different options, we
believe compacted recycled ash to be the best base material for synthetic turf due to its fantastic drainage
properties. If your artificial lawn doesn’t drain well, you could have all kinds of problems with
waterlogging, not to mention mould, mildew, and bacteria, particularly if you have pets that urinate
on the lawn.
We suggest using approximately 70mm of compacted ash to create your sub-base, spread evenly
across the surface of the landscaped area.
Step 4: Weed Membrane Layer 2
A second weed membrane layer will ensure that your imitation lawn remains weed-free for years to
come while protecting the latex backing. It helps drain dog urine away from the surface to remove
any unpleasant odours and creates an even surface for applying your fake grass.
You should apply the second layer of weed membrane in the same way as the first layer, overlapping
the joints for a secure seal.
Step 5: Lay Artificial Grass
Now you can get to the fun part of laying your artificial grass. With superior turf by Artificial Super
Grass, this part is simple. Just roll it out, trim it to size and secure it into place using rust-resistant
150mm galvanised U-pins.
When cutting it down, leave a 10cm margin to play with and do the final trimming once it is in place.
Cutting it too short could be a very costly exercise, and you’ll have a lot of extra work trying to fill in
When joining two pieces of artificial turf together, make sure that the pile is going in the same
direction for a uniformed finish. It will usually lean towards one direction when you first unroll it, but it soon straightens with a stiff broom or power brushing. You’ll need approximately 100 U-pins per 10m2 of synthetic
grass, and both joint tape and joint adhesive to secure pieces together.
Step 6: Power Brushing
The final stage in installing Artificial Grass in Rotherham is power brushing with a stiff broom or a professional
power brush to elevate every blade, they are a great way to keep your synthetic-lawn in perfect condition.
You may have seen people using regular hoovers on their fake grass which is also fine or a garden blower which will keep your lawn looking flawless and more realistic than you ever thought possible.
The Benefits of Professional Artificial Lawn Installation
While installing synthetic grass can be incredibly rewarding if you are a gardening enthusiast and a
dab-hand at DIY, it is not for everyone. If you are not confident in your abilities and are worried
about destroying your newly purchased astroturf, you should consider employing the professionals.
