Easy Installation

Fast and Easy The 9'10" length of the channels and built-in rebar anchors make installation fast and simple. Grates are not required during the pour and alignment clips keep your installation straight.

Extra Heavy Duty

Break, Chemical, Temp-Resistant Zip-Trench has four grate choices with Class C and E load rating options. The polypropylene material is break-resistant, impermeable, and offers more chemical resistance than polyethylene used by competitors. It can also handle temperatures up to 180°F.

Flexible System

Built-in Flexibility With 16 channels (12 sloping and 4 neutral) from a depth of 7-9/16" to 22-9/16", Zip-Trench allows for unparalleled flexibility with channels that can be run as long as needed.

Less Maintenance

Easy Cleaning Zip-Trench’s deep rounded base keeps water moving at optimal efficiency. The faster movement of water keeps debris moving and reduces the frequency of servicing.

Traditional Cast-in-Place Trench vs. Zip-Trench^®

Traditional Cast-in-Place Trench	6" or 12" Zip-Trench® Drains
🛠️ Labor intensive	⏳ 75% less labor*
💰 Inexpensive materials	💵 Overall, 25% savings*
🌊 Uses permeable concrete	🛡️ Polypropylene is 100% impermeable
📐 Requires complicated wood framework	⚡ Easy installation with male/female lap joints for speed

* Based on the costs associated with installing a 100' section of cast-in-place trench drain compared to the same length using Smith 9960 Zip-Trench. Cast-in-place installation requires 48 hours of labor compared to 11.5 hours when installing a Zip-Trench Drain.

Still Want to Use Cast-in-Place?

That’s okay. Zip-Trench^® frames and grates are compatible with cast-in-place installations.
