Open-cut (trench) method
Classic construction and repair of external networks with trench excavation — when open-cut is more rational than trenchless.
How the work is carried out
A simplified scheme of the key stages. Scroll to see the sequence.
Typical applications
- New construction on open land without hard surfacing
- Shallow networks with free access to the route
- Gravity sewerage with precise slope control
- Combined work: network + manholes + landscaping restoration
Things to consider
- In dense development, under roads and utilities HDD is usually more rational
- Water-saturated soils require construction dewatering
- Pavement and landscaping restoration is included in the estimate

FAQ
When is open-cut better than HDD?
On open land without surfacing, at shallow depths and when full access to the route is needed — open-cut is cheaper and allows precise slope control.
Do you restore the surface after work?
Yes, pavement and landscaping restoration is part of the design and estimate.
How is installation quality controlled?
We control bedding preparation, trench shoring, layered compacted backfill and test the network.
