Surface Ducting Installation

Ducting channels are installed in a continuous trench run, and are usually fully encased in concrete.

1. Excavate greater than the overall dimensions of the ducting channel.

2. Lay out ducting channels near the trench.

3. Ducting channels need to be supported at the correct height and held securely in place during the concrete pour.

4. To finish installation, pour concrete evenly either side of the trench. The top of the adjacent pavement should be above the lid level by approximately 3mm.
