Geotextile Membranes (Woven & Non-Woven)

We stock and sell Geotextile Membranes from top manufacturers such as Terram and Don & Low. We also sell Terram textile in custom sizes for ease.


What exactly are geotextile membranes?

Geotextile membranes are large pieces of fabric that are laid in the ground to act as a protective layer. They have a wide range of applications and functions depending on how and where they’re used – but they’re most commonly used in engineering and drainage projects involving land drains.

Selecting and buying geotextile membranes from EasyMerchant

Our high-quality geotextile membranes solve a range of problems – most commonly relating to the environment or solving ground working ground reinforcement issues. Our products are used by a wide range of customers – from people carrying out DIY projects – to civil engineering firms who buy enormous quantities for large-scale projects.

We can supply a vast array of textiles – each suited to slightly different uses, including:

  • Geocells
  • Woven geotextiles
  • Geocomposites
  • Non-woven geotextiles

Both Woven & Non-Woven types of membranes or fabrics are generally supplied in rolls of 4.5m wide by 100m long. We also sell membranes in custom sizes to make things a little easier for you – or, if you’d like to cut your textiles yourself, we can provide the tools you’ll need to do so quickly, safely, and accurately.

What are the different types of geotextile membranes available on the market?

The properties of white non-woven geotextile make it the perfect fabric for wrapping modular soakaway crates and for lining "French" drain soakaways and land drains. It is also used for ground stabilisation, landscape and building works and for a variety of soil separation & filtration applications.

Modern engineered membranes can go beyond just filtering fine sediment from the area though; within the terram fabric range you’ll find geotextiles specially developed to filter pollutants in the fluids passing through soil particles past the fabric membrane, preventing them from entering the underlying layers and contaminating ground water.

In the right circumstances some of these pollutants can be degraded to secure soil particles by naturally occurring microbes. Geotextile fabrics make it possible to treat drainage and flow filtration as two entirely separate issues.

No matter the need, add a geotextile fabric that's correctly specified according to its hydraulic properties and it will generate a filter zone - preventing small particles passing through causing problems such as siltation.

What are some membrane applications

Of course, our range of membranes is wide and varied – so there’s virtually no requirement we won’t be able to help you with. It’s always worth taking a look at what other customers have used our range of membranes for though – so you can quickly get a feel for whether a textile could help:

  • Permeable pavements and roads
  • Scour control
  • Green roofs
  • Ground stabilisation membrane under grass paved areas
  • Making gravel driveways
  • Separating stone layers in car parks or overflow car park building
  • With permeable paving surfaces
  • Engineering applications, including railway construction
  • Wrapping soakaway crates 
  • Coastal erosion protection & ground reinforcement
  • Providing drainage for horse arenas
  • For gravel-filled plastic paving grids to prevent the gravel intermixing with the larger sub-base stone layers
  • In road and pavement construction
  • Under block paving
  • Land drains
  • Water attenuation & rainwater harvesting

How to lay geotextiles - methods, steps, and helpful tips.

As long as you have the correct tools and follow a consistent procedure, laying a geotextile becomes a relatively simple job. We've broken the process down into 6 easy-to-follow steps:

  • Step 1: Prepare the area that's going to house your textile. This will generally be one of the most labour intensive part of the process as it can involve removing trees, roots, and other obstructions from soils. If you find pockets of soil that are weaker than the surrounding area, you should aim to replace these with a suitable granular fill/aggregate to ensure ground stabilisation.
  • Step 2: The area you're working with should be levelled and smoothed. 
  • Step 3: Your textiles should be rolled out in a suitable preparation area. When moved into position, the textiles should be as flat and as tight as possible.
  • Step 4: As you lay your rolls down, you should overlap according to the overlapping/joining procedure that comes with the product you're using.
  • Step 5: Again, according to the textile instructions, secure the fabric with the recommended materials. In some cases, this will be soil or another fill - although in other cases pins or staples can be used.
  • Step 6: Your fill can now be added to the textile. Layers of 8" to 12" are the norm - but if you're working with a weak subgrade material, this is often increased to 18" soil layers. 

Of course, it's important to follow the instructions that are specific to the fabrics you're using - but if in any doubt, you're welcome to call the EasyMerchant team who can track down the relevant information for you. 

How to join geotextiles - overlapping, taping, and stitching

There are different joining and overlapping methods that allow you to work with more than one sheet of geotextiles over large areas - and those methods will largely depend on the product you're working and the load capacity or 'baring ratio' (CBR) of the soil you're working with.

In some cases, using waterproof tapes will be perfectly adequate - although in other cases, you should seek expert advice to ensure the threading or overlapping method you're going to use will be adequate to protect against moisture and debris creeping through. Again, if you're in any doubt, you're welcome to get in touch with us here and at EasyMerchant - and we'll be able to help, or point you in the right direction for the information you need.

Some geotextile membranes FAQs

EasyMerchant customers often have questions that relate to geotextiles - so we've answered a few here to help you pick a product that's right for you.

"What types of membrane are available?"

Generally, membranes can be broken down into two types:

  • Impermeable geotextile membranes

These don’t allow water to pass through the membrane, meaning that they’re useful in retaining water within a certain space or stopping it from travelling through.

  • Permeable/porous geotextile membranes

These porous fabric pieces allow water to pass through and can be non-woven or woven.

"In which circumstances is it right to use geotextile membranes?"

Geotextile membranes are mostly used for drainage, protection, reinforcement, filtration and separation - where durability is key.

"What dimensions are Available?"

Both types of geotextile membranes are generally supplied in rolls of 100m long by 4.5m wide. For those working on smaller projects both types are also obtainable to buy by the metre.

"Are there geotextile membranes that will stop weed growth but still allow turf to grow?"

Yes, the best solution is a non-woven geotextile as it is a strong, thermally bonded fleece.

"What do the different statistics and numbers for non-woven geotextile membranes mean?"

Here are the common classifications used in the specifications for non-woven geotextiles:

  • CBR Puncture Resistance and Trapezoidal Tear Strength (durability)
  • Apparent Opening Size 
  • Permeability and Permittivity
  • Weight
  • Elongation and Grab Tensile Strength 

Where should you buy your geotextile membranes?

You probably won’t be surprised to discover that we think you should source your geotextiles through us here at EasyMerchant – but we’ve got a number of good reasons why!
