steel-plastic flexible permeable hose
Advantages:
1, Due to the different pressure underground,the water always flow from the high pressure area to low pressure area where drain hose been buried.the underground water,surrounding the drain hose,will be continuous movement will lower the level of underground water effectively without any soil collapse and chemical contamination..
2,Drain hose is able to lower the level of underground water,drain the surface and penetrating water out perforation area will decrease the soft soil and avoid soil collapse.
3, The aenetrable area of conventional HDPE is limited to the perforated area only,but raising up the perforation area will decrease the resistance of pipe against pressure.Pretty lion’s soft drain hose provide more advantages in both penetration and pressure resistance than HDPE and other perforated pipes.
4,Prettylion drain hose contains two parts:
Hose wall:it provide superior filtration,drainage and more penetration area.
Support:hose is suported by high tenacity steel wire to keep drainage effective.
