Bidim® Green is a premium nonwoven geotextile made from Australian recycled polymers, designed to provide an effective and economical solution to a multitude of engineering applications.
Bidim® Green nonwoven geotextiles provide an effective, economical and sustainable solution to a range of engineering problems including weak soil, rutted and cracked roads and liquid and gas leaks from landfill sites. All Bidim® Green nonwoven geotextiles are manufactured in Australia to ISO 9001 standards and are supported by a rigorous MQA process as well as being designed to meet the requirements of Australian and New Zealand road authorities.
Bidim® Green nonwoven geotextiles provide excellent filtration and feature a strong three-dimensional structure with high elongation. Bidim® Green nonwoven geotextiles also have a high melting point and high UV resistance.
Geofabrics is a proud member of the Infrastructure Sustainability Council of Australia (ISCA). Bidim® Green is now available on ISupply.
Bidim®Green nonwoven geotextiles have a three-dimensional structure designed to improve drainage performance. Ideal for use in subsoil drainage systems, Bidim® Green will assist in the removal of water from road and railway works, sports fields and behind retaining walls.
Bidim® Green nonwoven geotextiles can be used in the construction of roads, railways and embankments where the ground is soft and unstable. Using a layer of geotextile to separate the soft ground from the fill material will reduce the amount of fill required, increase the life span of the road or rail structure and cut long-term maintenance costs.
Bidim® Green nonwoven geotextiles are highly porous, allowing water to pass through while preventing soil migration. When used in revetment and subsoil drainage projects, Bidim® Green geotextiles are more cost-effective than natural filters.
Using heavyweight bidim® Green nonwoven geotextiles in landfills extends the life of the lining system by protecting it from punctures and excessive deformation. The geotextile acts as a cushioning and stress relieving layer, minimising the chances of leakage in the long term. Needle-free geotextiles are commonly specified in landfill and containment applications to prevent damage to the underlying liner.
Nearly every road built today uses a nonwoven geotextile such as Bidim® Green, to provide separation and filtration under the road formation. The ingress of water into road pavements poses the most significant damage potential to any road; therefore rapid removal of this water is of the utmost importance. Bidim® is the only bidimensional geotextile on the market today - meaning it has the same strength properties in both directions.
Standard road construction practice requires the inclusion of road edge drainage systems which incorporate geotextiles; in order to optimise the performance of these drains a geotextile with high flow rates is desirable. The three-dimensional structure of the nonwoven geotextile provides numerous flow paths, with the result that Bidim® Green geotextiles allow water to flow at rates which exceed most natural materials it is placed in contact with.
Geotextiles are commonly used in the rail sector to separate the capping layer form the ballast layer, providing separation and filtration.
The high-quality fill material can become contaminated when it is placed directly in contact with a soft or poor quality ground; the result being a loss of performance of the fill material. To limit the contamination and subsequent strength loss, geotextiles are used to separate the two distinct elements. Construction in this environment can place the geotextile separator under high stress with forces from rock placement and equipment loads needing to be transferred into the poor quality material. bidim Green geotextiles are ideal for this application as it combines high elongation with high strength to provide unsurpassed toughness and survivability characteristics.
Heavy-duty geotextiles are used to prevent damage to impermeable liners designed to contain harmful liquors in landfill and mining applications; the design of the liner system needs to limit the chance of punctures during installation and reduce the risk of long term stress cracking of the geomembrane. Needle-free geotextiles are commonly specified in liner protection applications to help prevent damage to the liner.
