NNS ServicesHighway Drainage
Water is the biggest enemy of a road in Nepal. We build roadside drains, culverts and gabion protection that carry monsoon runoff away before it can damage the pavement or the slope.
Our work on the Pokhara–Hemja corridor was carried out under live traffic while keeping the road open.
What we deliver
- Roadside surface drains and cascades
- Box and pipe culverts
- Gabion retaining and slope protection walls
- Sub-surface drainage and dewatering
- Works under live traffic management
