6 Oz Polypropylene Nonwoven Geotextile 150g M2 Non Woven Drainage Fabrics For Landscape Drain
About the application of PP nonwoven staple fiber geotextile
Civil Engineering Field
Road and Railway Construction
· Roadbed reinforcement: Improve soil strength and stability, reduce uneven settlement, suitable for flexible pavement repair and gravel slope reinforcement.
· Crack repair: Used for asphalt pavement crack repair to enhance the structural deformation resistance.
· Drainage system: Laid around the concealed pipe or gravel drainage ditch to prevent soil particle loss and ensure free flow of water.
Tunnels and underground engineering
· Seepage removal: Used for seepage treatment around tunnels to prevent water pressure from damaging rock and soil structures.
· Composite anti-seepage: Used in combination with HDPE membrane to enhance waterproofing effect.
Dam and slope protection
1. Dam reinforcement
·Isolate different rock and soil materials to prevent water scouring and erosion, and improve overall stability.
·Applicable to water conservancy projects such as reservoirs and flood control embankments.
2. Slope protection
·Prevent soil erosion and landslides, often used in eco-bag slope protection projects.
·Combined with plant growth to achieve environmental protection and greening.
GEOTEXTILE INST ALLATION
To pave by roll with artifical method, the fabric must be level and appropriately leave the margins for
deformation. The inst lation method usually has overlapping, sewing and welding.
The overlapping part is generally more than 0.2m.
It should be welded or stitched for the exposed geotextiles.
AII sewing must be continuously carried out(for example, point-sewing is not allowed),
the geotextiles must be overlapped more than 200mm before overlapping.
The minimum distance between sewing needle and the fabric edge(the edge of exposed material) is at least 25mm.
Notes
·Construction coordination: It needs to be used in conjunction with other materials (such as anti-seepage membrane) to enhance the effect.
·Specification selection: Select the weight (100g/m²~800g/m²) and thickness (0.3mm~20mm) according to the project requirements
