Wallbarn can supply a very large range of geotextiles, made from different materials in a whole host of densities and weights. We can select the exact product for the needs of the client and provide both the best technical performance and the most cost effective solution.
Geotextile fabrics are available manufactured in polypropylene or recycled polyester. The material is supplied packed into tight rolls and we can supply material in a variety of roll sizes, from 1 metre wide up to 6 metres wide for very large-scale projects. These super-jumbo rolls make installation much faster and easier as there will be less individual rolls to sew or seal together – ideal for applications such as landfills.
Flexible and Permeable Solution
The prime material supplied by Wallbarn is a high tenacity polypropylene fabric (PPS). This has been designed to be flexible and permeable but has increased tensile and puncture strength, making it suitable for hard wearing applications such as landfills and reservoirs.
Its soft, cushioning properties mean it can be placed onto rough areas to prevent sharp objects from passing through into the system above but still allow the passage of water. This means sealing and waterproofing sheet membranes can be installed above them without the risk of ground settlement causing any damage above.
This material is also ideal for road and rail construction, as it can withstand the forces of heavy traffic over the long term. The high tenacity PPS grade polypropylene fabric has also been used as an effective protection layer for waterproofing membranes including single ply sheet membranes. The cushioning effect is seen as a major advantage.
It has been used successfully as a separation layer in inverted waterproofing systems, protecting the insulation from damage caused by the ballast. It can be used between layers of asphalt, in tunnels, foundations and airport runways.
High Performance Materials
The properties exceed those of the leading brands on the market and very high performance can be achieved using these fabrics in a wide manner of applications.
A second grade of polypropylene fabric is available called PPX. This is manufactured in a similar way to the high tenacity product, but it has slightly lower mechanical properties.
The PPEX offers a more cost effective option for simple filtration or erosion control. Where there is not the requirement for such high tensile strength, a whole range of fabrics are available which still match the performance of many of the leading geotextiles in the market in a wide range of densities and roll sizes.
