PBTEX100 is our new non-woven, permeable geotextile fabric, engineered for superior performance. Manufactured from high quality polypropylene fibres, these fibres are spun-bonded together, with precision punched holes in the material, ensuring optimal functionality and durability. Designed to meet the needs of our customers, it provides reliable protection and performance in a variety of applications.
While offering excellent durability, PBTEX100 is lightweight and easy to cut and handle, making it ideal for low-load areas or where free water flow is crucial. Its permeable structure allows water to pass through while preventing the intermixing of fine particles, such as soil, which helps maintain separation between ground layers.
Generally, you can use it for functions such as filtration, drainage, and separation. Improving water movement and ground stability, it helps protect overlying surfaces and structural layers. You could also use it for applications such as weed control, where it restricts unwanted growth and still allows moisture to pass through.
Whether you’re working on landscaping, roofing, drainage, or filtration systems, PBTEX100 provides a reliable and easy to install solution to enhance the speed and longevity of your projects.
Some of the ways you can use it include paved driveways, permeable paving installations and -of course- resin bound gravel surfaces. The membrane helps to keep aggregates separate from the subgrade while allowing water to drain freely. This improves ground stability and extends the lifespan of your finished surface.
PBTEX100 is improving temporary access tracks and children’s play areas, offering unbeatable performance even on soft or unstable ground. In these situations, the membrane provides separation and support, improving load distribution and reducing the risk of surface deformation.
QuickFact: What studies show
A study cited in a ScienceDirect paper found ~30% reduction in surface rutting when using geotextile at the top of the subgrade.
Another test/simulation reported rutting dropping from ~3.8cm to 2.66cm (~30% reduction) when geotextile was installed at the subgrade/subbase interface.
What that means on a driveway / patio
For installing beneath driveways on soft ground:
ruts/settlement “tracks” form far slower, if at all
bedded layers stay true for longer
less chance of dips that eventually cause block movement and jointing loss
On wet clay, sub-base stone gets pressed into the subgrade under load (especially vehicle turning), resulting in direct stability loss. Geotextile acts as a separator and prevents:
aggregate punching into the subgrade
fines pumping up into the sub-base
One of our key benefits of PBTEX100 is its high tensile strength and resistance to tearing. This ensures the membrane retains its strength during installation and throughout its service life, even when subjected to load or ground movement. This means you can rely on the membrane to continue performing effectively, even under pressure, reducing the need for costly repairs or replacements over time.
Resin bound isn’t flexible like block paving. If the base moves, the resin bound surfacing can:
crack
debond in patches
mirror-settle (dips reflect through)
Using PBTEX100 geotextile as a separator under a granular sub-base helps by:
preventing pumping (fines migration)
keeping water moving through the structure instead of trapped sludge
maintaining the stiffness of the load-bearing layer
Another important benefit is its resistance to rot, chemicals and biological attack. This allows it to perform reliably, even in damp and intensive ground contact environments, where it offers long term durability, as the material will not break down over time even when exposed to harsh conditions.
A further benefit is it is a cost effective solution. This is due to its ease of installation and expected lifespan of over 25 years without the need for material replacement, helping to reduce long term project costs. With the money saved, you could now invest in more of our high-quality products, maximising your value and expanding your project capabilities.
PBTEX100 works by forming a reliable protective layer between the ground and overlying materials like aggregates or paving systems, separating different ground layers. This simple yet powerful function ensures the subgrade soil stays intact and prevents unwanted mixing, maintaining the stability of your surface for the long haul.
PBTEX100 also provides filtration. Its permeable structure allows water to flow through freely while keeping soil and silt where it belongs. By preventing these particles from migrating into drainage or aggregate layers, the membrane helps reduce clogging, ensuring your systems continue to perform as expected.
Moreover, it also supports controlled water flow, helping to manage excess moisture and reduce water buildup beneath surfaces. This is important in areas exposed to heavy rainfall. This added layer not only helps maintain ground stability but also improves long-term performance.
