Duraslot® Slotted Surface Trench Drain

Slotted surface trench drains for collecting heavy-duty surface runoff

Duraslot Linear Slotted Surface Trench Drains provide you a cost efficient, economical and corrosion-resistant method for intercepting sheet flow, storm water and surface runoff on infrastructure, commercial, residential and sports fields. Duraslot pipe helps solve your horizontal drainage needs by intercepting sheet flows across paved or cleared areas, or as it collects in low spots. It is a cost-effective substitute for corrugated steel-slotted drains, precast trench drains or cast-in-place trench drains.
