What are landscaping fabrics?

Landscaping fabrics can be broken down into three categories: weed control membranes, inclined landscaping membranes and geotextiles.

Weed control fabrics

Weed control fabrics are great to use anywhere you don’t want weeds! Some are just for use in flower beds, while others can be laid under lawns, driveways, decking or patios. Specialist fabrics like the DuPont Plantex Root Barrier can be used vertically to stop aggressive roots like bamboo from encroaching on other garden structures.

Inclined landscaping membranes

Inclined landscaping membranes are perfect for sloping gardens or steep embankments. Not only do they provide excellent weed control, they can also stop soil erosion and prevent mulch or other soil toppings from slipping down the inclined land.

Geotextiles

Geotextiles can also be used to control weeds, but they’re much more heavy-duty. As such, they’re more commonly used in ground engineering projects like roads or driveways where they help provide strength, stability and drainage capabilities. In the garden they can be used under hardscaping projects like patios, paths or decking, where they play a vital role in keeping different parts of the soil from mixing together and potentially destabilising garden structures. They’re also used in drainage projects, like soakaways and landrains, to stop any silt or debris from entering.

What are the benefits of landscaping fabrics?

Still undecided on whether to use some sort of landscaping fabric for your garden project? We’ve made a list of what membranes can do for you.

They can prevent waterlogging

Where land is flat, soils are compact or the water table is high, having a well-designed drainage system in place is a must. Without it, water may collect, undermining paths and patios, drowning expensive plants and turning lawns into big, muddy bogs.

If any part of your lawn is prone to waterlogging, putting in a drainage solution such as soakaway crates wrapped in a non-woven geotextile membrane like ACOWrap, ACOTex or Draintex can really help. This is pictured below in a domestic soakaway system.

If it’s your flower beds or borders that are prone to getting soggy in a downpour, any permeable weed control membrane can help drain excess water away from plants to keep them healthy.

They help stop soil erosion

Having a membrane in place can stabilise loose soil and stop it being eroded by the weather. Slopes and embankments are particularly vulnerable to soil erosion – and this can be dangerous. Not only can moving soil affect the growth of grass or plants, it could also destabilise the slope. Installing a quality inclined landscaping membrane such as DuPont Plantex Gold or DuPont Plantex Cocomat Erosion and Weed Control fabric, is a must.

They can stop soil and gravel from moving around too much

Planning on covering your driveway in gravel? Having a strong, woven geotextile membrane in place will keep the gravel in place and it will stop it from spilling onto the road. These geotextiles are designed to allow water through, whilst separating and stabilising the aggregate within.

It also makes gravel paths and soil easier to walk or drive on.

They can keep different parts of your soil separate

From potholes on your driveway to sagging bits of your lawn, when soil becomes compacted due to heavy use it can start to cause all sorts of unsightly problems.

Geotextiles not only help to absorb and spread the weight of heavy loads, they can keep different parts of soil separate to prevent sinking and rutting caused by aggregates settling into the soil beneath.

They can save you from hours of gardening

Always battling weeds in your beds and borders? Weed control fabric from DuPont or ProWeed can be laid on the ground below the topsoil and its structure. This allows air, water and nutrients to pass through, but prevents weeds emerging from dormant seeds below.

They extend the life to your paved paths or patios

Surface cracking is a huge problem in paved patios and it not only looks unsightly, it means that water can get in and cause further headaches.
Geotextiles like Wallbarn, Groundtex or TCS help you avoid cracking by providing reinforcement between the paving and soil beneath. This not only forms a moisture barrier, it can also absorb future stress to stop the spread of the dreaded cracks.

They help you be kind to the environment

By stopping the problem right at the source, putting in a weed control membrane helps to reduce the amount of aggressive chemicals and herbicides you need to keep your garden looking lush and beautiful.

They can create a green roof

A geotextile membrane like the one from Alumasc will help you create a green roof that not only looks attractive, but is low maintenance too. The fabric works double duty to ensure surface water drains away and that no roots penetrate through the roof.

Which landscaping membrane do I need?

Different fabrics suit different projects, and some work extra hard by controlling weeds, stabilising the ground and improving drainage all at the same time. Here’s a look at some of the common uses of landscaping membranes, and a suggestion of which type of landscaping membrane will work best for your project.

root-barrier-dupontTo control weeds

You will need: Weed control fabric

How it works: Weed control fabrics are designed to keep weeds from sprouting up through the soil. They allow air and water to pass through, whilst stopping weeds in their tracks.

Suitable for: Each product differs slightly (so you’ll need to read the label) but, in general, weed control fabric can be used to line flower beds and borders, or can be placed under timber decking, block paving and patios.

How to install: To put weed control fabric in a flower bed, cut the sheet to the right size and shape, and then cut holes where you want the plants to go. Secure the fabric in place with landscaping pins, then cover over with a thick layer of mulch. That way, the plants that you have intentionally planted will have access to the nutrients in the soil, but weeds aren’t able to sprout up through the protective layer.

Which weed control fabric to choose: There are several different options available, depending on your budget.

  • Proweed Control fabric from Drainage Superstore is extremely cost-effective and labour-saving. Made of non-woven polypropylene, you can buy it in a size to fit your project. Used with a top layer of mulch, bark, decorative stone or gravel, it can be used in flower borders, under timber decking and for gravel paths and patios, but you can’t use it under turf.
  • Market leader DuPont has a range of products, but for weed control where land is flat, you can’t beat its Weed Control & Landscape Fabric. The choice of professional landscape gardeners, not only does it provide an unbeatable weed growth barrier, it can also give you stable foundations, prevent the mixing of soils and add drainage, making it the perfect choice for patios, block paving and timber decking.
  • If you’re planting in a new build site, try the DuPont Plantex Cocomat which is finished with aesthetically pleasing natural coconut fibres instead.
  • Another multipurpose weed control fabric that doubles up as a ground stabiliser is the range from Groundtex. Made of tough woven fabric, it has excellent strength and tear resistance when used below driveways and paths, yet it can also be used as a heavy duty weed barrier.

To control roots

You will need: A specialist root barrier

How it works: A non-permeable root barrier is used vertically to prevent particularly aggressive roots such as bamboo from encroaching on the rest of a garden or disrupting the structure of a road or pathway. You can also use a root barrier to contain a planted area by placing a barrier in a circular structure around it.

Suitable for: Used around aggressive plants where the roots may threaten paved areas, roads, lawns, patios or building foundations.

How to install: You’ll need to dig a 70cm deep trench running around the diameter of the plant whose roots you wish to control. Then install your root barrier vertically, lining the inside of the trench including up the sides. Fill up with soil, leaving a 2cm overlap of root barrier above the surface.

root-barrier

Which root control fabric to choose: Drainage Superstore stocks two products that deal with root control:

  • One of the strongest products on the market, Dupont Root Barrier is a technically advanced fabric which prevents and contains invasive growth, even from aggressive plants like bamboo and hypericum. It encourages the roots to grow downwards, while also protecting them from pollutants.
  • For controlling roots on roof gardens and green roofs, try the specialist Rootbar product from Icopal. It stops roots from penetrating and allowing water to get in, and it can be used on either flat or sloping roofs.

To control weeds and stop soil erosion on slopes

cocomatYou will need: Inclined landscaping membrane

How it works: These specialist membranes not only control weeds and promote plant growth, they also work to minimise soil erosion – a huge problem on slopes and steep embankments. But it’s not just soil that’s protected – mulch or wood chips are also able to stay in place.

Suitable for: For use in areas with up to a 60 degree pitch.

How to install: Simply cut the membrane to the right size with a regular pair of scissors and use some landscaping anchor pins to create a single layer that is anchored into the ground.

Which inclined landscaping membrane to choose: Drainage Superstore has a range of landscaping membranes specifically designed for inclined areas:

  • DuPont Plantex Gold has a 25-year product guarantee and is up to five years UV stable. Use it on sloped embankments and sloped driveways, where mulch or other toppings don’t hold in place.
  • DuPont Plantex Cocomat Erosion and Weed Control fabric looks natural and offers immediate protection against wind and water erosion plus superb weed control in just a single fabric.

For ground stabilisation and soil separation

You will need: dupont-groundgridA strong geotextile membrane. This could be woven, but sometimes a non woven membrane may be chosen to add extra drainage capabilities. Alternatively use a pre-made gravel grid, as pictured left.

How it works: Different types of soil can have different consistencies. When soil mixes in the rain, the ground can become uneven and even sink as small particles get washed down in between the larger soil particles.

Geotextile membranes prevent this from happening. They keep different layers of soil separate, meaning any hardscaping built on top will be strong and secure.

Suitable for: Perfect for use under roads or driveways, paths or patios.

How to install: Prepare the base by removing large stones or debris that could cut or tear the fabric. Then roll out your chosen geotextile over the prepared area, keeping overlaps to a minimum. Secure in place using fixing pegs, then put the sub base over it, compacting it with a roller.

Which geotextile membrane to choose: Drainage Superstore stocks a variety of products that are perfect for ground stabilisation and soil separation.

  • Drivetex is a professional driveway fabric used specifically for ground stabilisation, yet it also has excellent filtration and drainage properties too. It can prevent sinking and potholes caused by the settlement of aggregates into the soil beneath and does not lose strength when used below ground, making it the perfect choice for areas that are subject to a lot of stress and strain.
  • Groundtex is made of tough woven fabric and has excellent strength and tear resistance when used below driveways and paths.
  • Earthworx is an extra heavy duty, non-woven geotextile widely used for roads, car parks, foundations and retaining structures.
  • TCS Geotechnics provide both woven and non-woven products and are a leading provider of specialist geotechnical products for the construction and civil engineering industries.
  • Terram is so famous within the industry that many people call all geotextiles ‘Terram’. Its non-woven geotextile is particularly robust, making it suitable to use even when the potential for installation damage is high. It can take high levels of stress and strain without the risk of puncture.
  • Wallbarn is widely known for its durability. Its non-woven geotextile products can be used to stabilise soil and sand under patios and decking because it makes even notoriously unreliable building surfaces more stable.

filtration geotextileFor drainage or filtration

You will need: A non-woven geotextile.

How it works: Non-woven geotextiles are excellent at allowing water to pass through whilst keeping fine particles of soil out. One of their most common uses is the wrapping and protection of soakaway crates and land drains, but that’s not all they do. Non-wovens are also used beneath domestic patios and block paving bases, keeping the granular layer apart from the soil whilst still allowing the water to drain away freely.

Suitable for: Ideal for use in soakaway systems and land drains, and beneath domestic patios and hardscaping.

How to install: To use non-woven fabrics in a soakaway system, wrap every side of your crate in the geotextile fabric and fix it in place with staples or strong tape.

Which drainage of filtration fabric to choose: Drainage Superstore stocks a number of products that deal specifically with drainage.

  • Draintex is a standard duty, non-woven geotextile fabric with excellent drainage and filtration properties. It’s perfect for lining trenches when constructing a French drain and for wrapping soakaway crates. It can also be used as ground stabilisation membrane in many hard landscaping projects.
  • ACO make products specifically for lining soakaway crates. They also sell a protective fleece that can protect the geomembrane from mechanical damage.
  • Wallbarn sell products targeted specifically at drainage. They allow the flow of water through the soil without any clogging.

Do I need a woven or non-woven geotextile?

Ensuring you choose the right geotextile fabric for your project means understanding the basic differences between them. So should you chose woven or non-woven?

Woven geotextiles

What are they?

Woven geotextiles are made by weaving polypropylene tapes together in a crisscross pattern. This makes the fabric super-strong.

What they’re used for?

Their high tensile strength makes woven geotextiles suitable for use under patios, paths and parking areas.

Advantages vs Disadvantages

Strong and economical, woven geotextiles are a little cheaper than non-woven and because of their extra strength woven geotextiles have a greater load capability. However, woven geotextiles offer only limited drainage and filtration capabilities compared to the non-woven variety, and they can lose strength over time.

Below is woven membrane to the left and non-woven to the right.

woven-vs-non-woven

Non-woven geotextiles

What are they?

Non-woven geotextiles feel a bit like felt. They’re made by thermally bonding polypropylene which is then finished by using needle punching.

What they’re used for?

Although non-woven fabrics have a lower tensile strength than the woven variety, they’re still strong and durable. Their main advantage is that they offer excellent drainage capabilities, making them ideal for use beneath driveways and roads where long-term ground stabilisation and filtration is required.

Advantages vs Disadvantages

Easier to cut, durable and strong, non-woven fabrics provide excellent drainage and filtration without losing strength over time. This type of geotextile does however have lower tensile strength compared to woven.

How easy is it to fit landscaping membrane?

Landscaping membrane is easy to install, provided you buy the right size you need for the job. It’s good to keep overlaps to a minimum, so looking for a roll that’s nearly the same size as your project is a great start.

For paths, choose a narrow, long roll (for example, one that’s 1m wide and 15m long). For a square area such as a patio, look for packs that are wider and shorter, like 2m wide and 10m long, for example. For large surface areas, some maxi rolls can be 100m long and come in widths of up to 4.5m.
