Green Inbitex Non-Woven Geotextile Fleece 105gsm

Pollution-Filtering Geotextile For SUDS & Permeable Paving Systems 

Green Inbitex is a specialist non-woven geotextile designed for use in sustainable drainage systems (SUDS), where it filters, separates, and actively aids the biological cleansing of stormwater.

Designed To Filter & Clean Stormwater

Inbitex combines physical filtration with a biological cleaning process. It encourages the growth of naturally occurring microbes that break down pollutants like hydrocarbons and organic material.

Its dual-layer construction – from polypropylene and polyethylene – creates a fibrous structure with microscopic dish-like recesses. These support microbial colonies, even in dry conditions, enhancing long-term performance. Used above or below the sub-base, Inbitex protects lower layers from clogging and boosts water quality entering storage tanks or aquifers.

Key Features

• Filters and cleans stormwater within SUDS installations

• Retains fine particles and prevents clogging of the sub-base

• Encourages microbial breakdown of hydrocarbons

• Dual-layer structure supports microbial activity during dry spells

• Suitable as both upper and lower geotextile layer in permeable systems

• Compatible with rainwater harvesting and infiltration tanks

Typical Applications

• Permeable paving systems (e.g. Formpave Aquaflow)

• Rainwater harvesting systems

• Attenuation and infiltration tanks

• Pollution control in SUDS setups

• Urban drainage and car park installations

FAQs

Where is Inbitex typically installed?

Inbitex can be used as both a top and bottom filter layer within permeable paving systems. The top layer prevents fines entering the base, while the bottom layer filters and treats water before discharge or storage.

What does Inbitex filter out?

It retains fine aggregate, silts, hydrocarbons, and other pollutants. Its structure supports microbes that actively degrade oils and organic waste.

Can Inbitex be used in rainwater harvesting?

Yes. Inbitex helps pre-treat water before it enters storage tanks, improving water quality and reducing maintenance.

Is it UV resistant?

Inbitex is delivered in UV-protective wrapping. For best results, install immediately after unwrapping to prevent degradation during prolonged sunlight exposure.

How does microbial action work?

The unique surface of Inbitex creates micro-environments that support microbial life, even in dry periods. These microbes biodegrade contaminants like oils and organic matter in the stormwater.
