Channel Features & Benefits

Pre-Sloped Radius Channels

Standard PolyDrain channels have a built-in 0.6% slope , a smooth interior finish, a radius bottom, and a narrow cross-section. These features, which can produce a flow velocity of up to 10 times that of a standard hand-formed trench drain. This higher velocity provide excellent hydraulic efficiency and helps keep the channels clean.

Interlocking Joints

PolyDrain channels have interlocking "tongue & groove" joints that serve two important functions. First, they aid in maintaining proper channel alignment during installation. Second, they help prevent concrete migration into the system during the pour. ABT maintains a full line of joint sealants that can be applied to joints and connections when a sealed system is required.

Anchoring Ribs

PolyDrain channels are formed with full-length anchoring ribs, one each on either side of the channel at the base of the side wall. These anchoring ribs provide a positive mechanical lock with surrounding concrete.

Red Dot and Green Dot Inserts

All standard PolyDyn PolyDrain channels come with our polyethylene Red Dot inserts. The PolyChampion Channel have polypropylene Green Dot inserts. These patented inserts , together with grate locking devices, comprise the PolyLock Grate Lockdown System. Using this unique system, grates are blind locked without the need of special tools. Both Red Dot and Green Dot inserts provide vibration dampening that helps keep grates secure under the most severe traffic conditions.

Vertical Outlet Plate Adaptors

Vertical outlet details are cast into every fifth sloping PolyDrain channel or on every meter long non-sloping channel. These details are to facilitate secure outlet pipe connections. Vertical Outlet Adapters are also available to make pipe connections even more convenient.
