Preparing the Trench
You need to get the trench ready for the mesh and cables. Follow these tips to do it right:
| Best Practice | Description |
| Trench Depth | Dig the trench deep enough to allow at least 800mm (32 inches) of cover above the cables. In hard rock, 300mm (12 inches) with extra concrete is acceptable. |
| Trench Width | Make the trench wide enough for the cable and mesh, but not too wide to avoid extra costs. |
| Pilot Holes | Dig pilot holes every 25-30 meters to check for other services. These holes should be at least 150mm deeper and wider than your planned trench. |
| Locate Services | Use cable locators or ground penetration radar to find all existing cables and pipes before you dig. |
| Safety Measures | If the trench is deeper than 1.2 meters, use supports and never work alone in the trench. |
First, mark where you will dig. Use a cable locator to find any wires or pipes. Dig pilot holes to check for other things underground. Make sure the trench is straight and smooth. Take out sharp rocks or trash that could hurt the mesh or cables.
Laying the Mesh
When the trench is ready, you can put down the mesh. This step helps keep cables safe and stops damage.
- Roll out the warning mesh or tapes along the trench.
- Put the mesh 30 to 50 centimeters above the cables or pipes. This gives a warning before someone hits the cables.
- If you use detectable mesh, put it halfway between the service and the ground. This makes it easy to find with tools.
- Use Boddingtons crimps and a crimping tool to join mesh pieces. This keeps the mesh strong and helps with detection.
- Make sure the mesh is flat and covers the whole trench. Do not let it fold or leave gaps.
Note: The mesh should be easy to see and cover all cables. This makes repairs easier and keeps the mesh safe.
Securing and Covering
You must keep the mesh in place so it does not move. If the mesh moves, it can cause problems later.
