Installation of 32mm pipe across 15m Tarmac roadway:
| |
Volume Excavated |
Area Reinstated |
Typical Time Taken |
Other Effects |
Potential Saving |
| Open-Cut trench 750 x 150mm x 20m long |
2.25cu.m |
3sq.m |
10man-hrs |
Road closures, visible reinstatement |
None |
| Using a 45mm Mole, two pits 15 metres apart,
750 x 150 x 750mm |
0.17cu.m |
0.2sq.m |
2man-hrs |
Road fully open throughout process |
Approx. 15 times cheaper! |
The example outlined above shows how much more efficient
a Trenchless installation can be.
- Cost savings are made in many areas:
- Less excavation
- Less spoil removal
- Less bought-in backfill materials
- Less surface reinstatement
- Less road closures
- Less time taken
