Geotextile fabrics for drainage, filtration and soil stabilisation

Polypropylene Geotextile Fabrics 1Wallbarn distributes a wide variety of top quality nonwoven geotextile fabrics in different densities, roll sizes and type to suit any application.

These top quality high strength fabrics are manufactured from virgin fibre polypropylene, designed to give the highest mechanical properties for heavy duty construction projects.

Wallbarn has the largest range of geotextile thickness, weight and roll size of any UK supplier.

Geotextile fabrics are permeable, water can pass through the fibres but the particles remain in place. The soil and other particles will remain in place, avoiding waterlogging, erosion and subsidence; giving a dryer, stronger and more stable ground base for construction.

Our non-woven, high tensile fabrics are made from the best quality raw materials and manufactured to the highest standards, which provide uniform and consistent strength throughout the roll, so no weak spots will appear.

The fabrics are manufactured in a large amount of different thicknesses. This allows water flow at different speeds, depending on the density of the fleece.


Polypropylene Geotextile FabricsWallbarn can supply geotextile fabrics in a large variety of roll sizes, from 1 metre wide for small or restricted access areas (particularly roofs); up to 6 metre wide Jumbo rolls for very large projects.

These large rolls make installation faster and easier, since less individual rolls mean fewer joints to seal and less overlap at the joints is required, leading to less material wastage. Fewer joints also lead to a stronger overall system.

Polypropylene Geotextile FabricsWallbarn geotextile fabrics have been used successfully in the following applications:-

  • Filtration and separation for landfills and reservoirs
  • Protection layers beneath pondliner membranes

  • Soil stabilistation beneath building construction
  • Separation and stabilistation in road and rail construction
  • Separation and stabilistation in airport runway construction
  • Erosion control for embankments and cuttings
  • Soil stabilisation and separation in watercourses
  • Filtration and protection for tunnels and bridges
  • Roof gardens and green roofs
  • Protection layers in inverted waterproofing systems



Polypropylene Geotextile Fabrics 7Wallbarn virgin fibre polypropylene fabrics are used to give an effective separation between soil and foundation layer of larger particles whilst still allowing the flow of moisture.

The larger stones and finer particles do not get mixed together meaning there is far less risk of clogging. This improves the stability, strength and the drainage of the ground.

The geotextile fabrics can act as a strong barrier to particles whilst still allowing free drainage. This prevents soil from slumping in constructions such as artificial islands, embankments and cuttings.

Geotextile fabrics also preventing the ingress of fines into drains and outlet pipes. Often underground permeable pipes will be wrapped in geotextile to prevent them becoming clogged up over time.

Polypropylene Geotextile Fabrics 10Another popular application for these fabrics is for roofing and inverted waterproofing systems, being an ideal separation, filtration and protection layer beneath paving slabs or other coverings.

Higher density geotextile fabrics are also used as a temporary protection layer on top of waterproofing membranes to prevent them being damaged during the construction process.

It can be rolled out and taken up as a temporary protection, or fixed permanently.

Strong enough to tolerate vehicular traffic, and with special types that can withstand high temperatures, Wallbarn can supply geotextiles fabrics which can tolerate direct contact with asphalt.

Polypropylene Geotextile Fabrics 13It is essential that very high strength fabrics are used, manufactured from virgin fibre.

Wallbarn’s range of high tenacity fabrics match and exceed the tensile strength and puncture resistance of other brands on the market and purchasers benefit from being able to use lower weight fabrics to achieve the same mechanical strength.
