Product Information

Outline

These pipes consist of a strong, high water-permeable polypropylene filter and ribbed supporting structure. This prevents earth and sand from entering the pipes, while ensuring a smooth water-absorption effect over the entire pipe surface.

Characteristics

• Excellent permeability
  The pipe part uses polypropylene nonwoven fabric, with a large permeable area to display an excellent permeability.
• Blocks any inflow of earth and sand
  Because of the filter effect, no earth or sand can enter through permeation holes like in perforated pipes.
• Excellent initial absorption capacity
  The high-performance nonwoven fabric smoothly absorbs soil water.
• Clogging problem solved
  Because sand is used for backfilling, and the pipe and sand have the same absorption coefficient, no fine-grained soil can penetrate into the pipe, and it is less likely to clog the holes.
• Resistant to soil pressure
  The structure of the pipe, which uses a highly rigid reinforcing rib made of polypropylene, ensures resistance to crushing or breakage caused by soil pressure.
• Light body for excellent workability
  One roll of TDZ-100 (20 m) weighs only 10 kg, allowing speedy handling and excellent workability.
• Matches uneven soil settlement
  The excellent flexibility makes it possible to tailor the piping to the installation site, even when laying it in a curve. The piping will even match the uneven settlement of the installation soil.

Uses
