We would like to introduce our back drainage materials for retaining walls, "Pat Filter/TM Filter." The "Pat Filter" was developed with the aim of achieving reliable drainage effects with simple installation. The maintenance of retaining walls and irrigation channels depends on the quality of the back drainage. The "TM Filter" is suitable for cases where the back of the retaining wall is fully backfilled with stones or gravel, as well as for block and stone masonry retaining walls. 【Pat Filter Features】 ■ Increases drainage effectiveness from drainage holes ■ Prevents damage from uplift or frost heave in irrigation channels ■ Prevents the outflow of backfill soil and is less prone to clogging ■ Easy to install *For more details, please download the PDF or feel free to contact us.
