Toyo Drainpipes Z
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.
