Project Overview
The Van Ninh–Cam Lo section of the Ho Chi Minh Highway is a critical infrastructure development in central Vietnam, forming part of the country’s strategic north–south transport corridor. Linking Van Ninh in Quang Binh Province to Cam Lo District in Quang Tri Province, this expressway enhances regional connectivity and supports economic growth across the eastern corridor.

The Challenge
Constructing this route presented significant geotechnical challenges. The alignment traverses soft soils, high embankments, and multiple cut slopes requiring reliable stabilization. In addition, central Vietnam’s intense rainfall and flood-prone conditions demand robust drainage and erosion control solutions.

Several sections feature steep cut slopes where surface instability poses risks to long-term performance and uninterrupted traffic flow. Effective surface strengthening was essential to ensure safety, durability, and resilience against environmental conditions.

The Solution
To address these challenges, a combined slope protection system using Steelgrid HR30 and MacMat HS100 was implemented along critical cut slope sections.

This integrated solution delivers both:

• Structural surface stabilization, and
• Erosion control with ecological restoration

The system combines a high-strength steel mesh (Steelgrid HR30) with a reinforced geomat (MacMat HS100), forming a flexible and durable facing solution. Typically used alongside soil nailing or anchoring systems:

• The steel mesh provides mechanical reinforcement and surface restraint,
• The geomat protects against erosion while promoting vegetation growth

Together, they ensure long-term slope stability while supporting sustainable, green infrastructure development.
