Bidum Non Woven Geotextiles

Non woven geotextile designed to provide effective and economic engineering solutions.

Description

bidim® is a nonwoven geotextile designed to provide effective and economic solutions to a multitude of engineering applications. Introduced into Australia in 1978, bidim® geotextiles have a proven track record, which is unsurpassed. bidim® nonwoven geotextile is manufactured to the highest international standards and has ISO 9001:2008 accreditation.

As a result you can rely on the fact that, when you use bidim® geotextiles for your construction project, you receive the same high quality from the first to the last metre on the roll. Geofabrics is the only geotextile manufacturer in Australia, with plants in Albury and Southern Queensland.

As Australia’s geotextile supplier of choice we pride ourselves in providing the best service to customers throughout the country. The knowledge gained over the past 35 years allows our technical staff to provide relevant support based on local conditions and sound experience.

Applications

REVETMENTS

The loss of soil from behind a revetment will have an adverse effect on the stability and effectiveness of any revetment. Due to their ease of construction and low cost, geotextiles have replaced granular filters in revetment applications; with the nonwoven geotextile acting as a natural graded filter. bidim® geotextiles are designed to resist impact damage and to retain soil particles without significantly reducing the permeability requirements of the revetment.

ROADS

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. Standard road construction practice requires the inclusion of road edge drainage systems which incorporate geotextiles; in order to optimise 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® geotextiles allow water to flow at rates which exceed most natural materials it is placed in contact with.

EMBANKMENTS

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. In order to limit the contamination and subsequent strength loss, geotextiles are used to separate the two distinct materials. 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® geotextiles are ideal for this application as it combines high elongation with high strength to provide unsurpassed toughness and survivability characteristics.

LINER PROTECTION

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. Research has shown that bidim® geotextiles can significantly reduce forces placed on the impermeable liners, protecting them in both the short and long term.
