Typar® Spunbound Geotextiles

Overview
Typar® Spunbound Geotextiles are advanced materials designed to create a separation layer within subgrade soil, enhancing the performance and longevity of civil engineering projects. These geotextiles effectively develop a graded aggregate filter layer that maintains the separation between different soil types, thereby minimizing the risk of soil mixing or 'pumping'—a phenomenon where fine particles migrate under pressure.

How They Work
The unique construction of Typar® Geotextiles involves bonded fibers that form a network resembling a well-graded aggregate filter. This structure facilitates effective drainage and filtration by allowing water to flow freely while retaining soil particles. The high permeability of Typar® remains consistent even under compaction, ensuring that it continues to perform effectively over time.

Benefits of Typar® Spunbound Geotextiles

1. Prevention of Soil Mixing:
   By maintaining a clear separation between valuable base aggregate and underlying subgrade soils, Typar® Geotextiles help to prevent unwanted mixing, which can lead to structural weaknesses.

2. Enhanced Drainage:
   The filtration capabilities of Typar® improve the drainage of subgrade soils, reducing the risk of water accumulation that can lead to erosion or weakening of the foundation.

3. Reduction of Fine Particle Migration:
   The geotextiles effectively minimize the movement of fine soil particles into the base aggregate, preventing 'pumping' and maintaining the integrity of the base layer.

4. Cost Efficiency:
   By reducing the amount of base aggregate required and ensuring long-term durability, Typar® Geotextiles contribute to cost savings in construction and maintenance.

5. Long-Term Base Protection:
   The use of Typar® helps assure the long-term prevention of base deterioration, extending the lifespan of the structure and reducing future repair costs.

In summary, Typar® Spunbound Geotextiles are an essential component in modern civil engineering, offering effective separation, filtration, and drainage solutions that enhance the performance and durability of construction projects.
