- 1. DuPont Typar速 SF The ultimate choice March 16th, 2021
- 3. Typar速 a unique product DuPont Typar速 is manufactured using a unique integrated process in which continuous filaments of polypropylene are spun and immediately formed into a web that is thermally and mechanically bonded at filament crossover points The bonding method gives a unique combination of properties: High initial modulus (stiffness/rigidity) Excellent uniformity High strength 3 INTERNAL USE ONLY
- 4. The ideal combination of properties Mechanical properties Hydraulic properties Typar速 Energy absorption High initial modulus Excellent filter properties Constant permeability 4 INTERNAL USE ONLY
- 5. Mechanical properties a superb all-round performance Combination of initial modulus and elongation High resistance to damage during installation 5 INTERNAL USE ONLY Low elongation low rutting Stabilization allows rutting to be reduced vs. needle-punched materials High initialmodulus
- 6. Hydrophilic properties for effective filtration Effective filtration by creating a natural soil filter 6 INTERNAL USE ONLY Potential clogging of thick filters: no clogging thanks to the thin pre-compressed structure NATURALSOIL FILTRATION LAYER BRIDGING NETWORK TYPAR速 SF WATER FLOW SOIL THICK GEOTEXTILE DRAINAGE LAYER PARTICLES CLOGGING PARTICLES PASSING
- 7. Higher permeability for better filtration Typar速 SF structure similar to natural soil 7 INTERNAL USE ONLY Typar速 SF retains its permeability under in-use loads, contrary to needle-punched geotextile Pre-compression of Typar速 SF ensures that pore size is not reduced or enlarged, resulting in long- term filtration efficiency No complete blocking or blinding due to large number of pores and random pore-size distribution
- 8. A broad range of functions 8
- 9. A broad range of functions Filtration 9 INTERNAL USE ONLY Protection Drainage Stabilisation Separation Typar速
- 10. Efficient separation and stabilisation Aggregate savings Increased compaction Enhanced load-bearing Improved rutting resistance Improved frost resistance Increased bearing capacity of the soil and reduced differential settlements because of energy absorption 10 INTERNAL USE ONLY
- 11. Outstanding in filtration TOPSOIL TYPAR速 SF 11 INTERNAL USE ONLY FREE FLOW OF WATER DRAINAGE LAYER Fines dont migrate: after initial build-up of the natural filter, no further migration of fines Permeability remains constant, even under soil pressure Erosion of topsoil is prevented Long-term filtration is assured
- 12. Protection against puncturing TYPAR速 SF (separation / filtration) 12 INTERNAL USE ONLY WASTE SANDLAYER TYPAR速 SF (protection) DRAINAGE LAYER GEOSYNTHETIC BARRIER (geomembrane) COMPACTED CLAY LAYER NATURALSOIL In landfills, Typar速 SF ensures the protection of geomembranes and geosynthetic systems during installation and over time
- 13. Efficient and durable drainage NEEDLE-PUNCHED GEOTEXTILE TYPAR速 SF NON-COMPRESSIBLE DRAINAGE CORE DRAINAGE CAVITY NON-COMPRESSIBLE DRAINAGE CORE DRAINAGE CAVITY Evacuation of water or leachate 13 INTERNAL USE ONLY Efficient drainage requires a non-compressible core and a robust geotextile filter Typar速 stiffness makes the difference
- 15. Typar速 SF: the ultimate choice 15 INTERNAL USE ONLY High energy absorption Outstanding uniformity High initial modulus Long-term filtration High elongation
- 16. Practical advantages Consistent performance Excellent product uniformity over the entire roll Easy to handle Can be carried by 2 people Simple to cut Ease of installation Pre-compressed Typar速 SF doesnt absorb water so it can be installed in muddy or even winter conditions Simplified logistics Pre-compressed Typar速 SF requires less storage space and fewer truck movements Large choice of roll sizes 16 INTERNAL USE ONLY
