bidim® is a nonwoven, needlepunched geotextile used in civil and infrastructure applications for separation, filtration and drainage. It is manufactured to provide consistent hydraulic performance and mechanical durability in earthworks, pavement structures and drainage systems.
For smaller-scale and domestic applications, bidim® is also available in convenient bidim® Flashpack® formats. Flashpacks provide the same core geotextile functionality in pre-cut, easy-to-handle sizes suitable for household, landscaping and garden use.
Installed as a filtration interface in subsoil drains, trench drains, and behind structures to prevent soil ingress while maintaining hydraulic performance.
Used between dissimilar materials to limit intermixing, supporting improved load distribution and long-term pavement performance.
Functions as a filtration layer beneath erosion control measures, allowing pore water pressure dissipation while retaining underlying soils.
