Geotextile Felt is a high-performance technical textile material manufactured from polypropylene (PP) or polyester (PET) fibers, produced in both nonwoven and woven types for construction and infrastructure applications.
It is widely used as a protection, separation, filtration, and drainage layer in waterproofing and civil engineering systems.
PRODUCT STRUCTURE
Geotextile Felts are manufactured as:
- Nonwoven geotextile (needle-punched)
- Woven geotextile
Depending on project requirements, different grammage and strength classes are available.
KEY PERFORMANCE FEATURES
- High puncture resistance
- Excellent tensile strength
- Load distribution capability
- Impact protection for membranes
- Allows structural movements without damage
- Durable and long-lasting performance
Thanks to its mechanical strength, it protects waterproofing membranes against mechanical damage during backfilling and service life.
FUNCTIONAL BENEFITS
Geotextile Felt provides:
- Protection of waterproofing layers
- Separation between different soil layers
- Filtration of water while preventing soil migration
- Load distribution in foundation systems
- Improved drainage system performance
By reducing stress concentration, it minimizes the risk of cracking in foundations and structural elements.
APPLICATION AREAS
Geotextile Felts are commonly used in:
- Building foundations
- Retaining walls
- Terrace systems
- Roof waterproofing systems
- Metro tunnels
- Bridge piers
- Road and infrastructure projects
- Drainage systems
It is an essential complementary material for professional waterproofing systems.
WHY USE GEOTEXTILE FELT IN WATERPROOFING SYSTEMS?
When used together with bituminous membranes and drainage boards, geotextile felt:
- Extends the service life of waterproofing systems
- Prevents mechanical damage
- Improves overall system durability
- Provides safer and more professional application results
