One-piece unit - provides both grate
openings and trench drain combined. No
removable or loose parts that could be
lost, stolen or create a hazard to fast
moving vehicles. Simple installation requires
no bracing and no grates to install. |
 |
Abrasion resistance - testing showed
0.01” depth of wear after 30 minutes
of continuous abrasion - ASTM C779
(Procedure A - revolving disks). This is
comparable to Portland cement concrete. |
 |
Neutral or sloped depth system -
sloping (0.6%) 4-foot channel units provide
100’ continuous slope. This equates to
1/16" fall per linear foot. Neutral units can
be used to extend run lengths. |
|
 |
Large, high capacity inlet slots - provide
30% open area which equates to
36.20 sq. in. per linear foot. Openings
are tapered to allow large debris items to
fall through and prevent slots becoming
blocked. Slots can be used to suspend
parts in hanging installation method. |
 |
 |
4-bolt ductile iron access grate -
provides access to the drainage system
and underground pipe work for maintenance.
Supplied on access and outlet channels
only. Grate provides 38% open area which
equates to 43.24 sq. in. per linear foot. |
 |
 |
Polymer concrete construction - offers
high durability and is resistant to road
salts and other common road chemicals.
Polymer concrete is manufactured from
polyester resins reinforced with mineral
aggregates and fillers. It provides up to
four times the compressive strength of
cement concrete. Minimal water absorption
properties prevent freeze-thaw breakdown. |
 |
 |
Profiled side-wall pockets -
to increase
strength, reduce weight and hold unit
securely into concrete haunch. |
 |
Direction arrows - indicate flow direction
and ensure channels are installed correctly. |
|
 |
Male/female interconnecting end
details - help ensure correct height
alignment of units for easy installation and
aesthetic finish. |
|
 |
Flume outlets - offer high capacity outlets
for connection into a collector line or
catch basin. Fits to the base of the outlet
channels. Available as 8” or 12” Schedule
40 vertical or horizontal outlet. |
|
 |
8” (200mm) internal width - offers
excellent drainage capacity for any road
catchment area. |
