Project Context
This project addressed localized slope instability and surface runoff concentration along the Corredor Norte highway.
The objective was to control erosion, safely convey stormwater, and protect the roadway infrastructure through a coordinated system of concrete drainage elements.
We contributed to the engineering definition, constructability review, and technical execution of the proposed solutions.
Engineering Scope
The intervention combined multiple rigid concrete hydraulic structures, each responding to a specific hydraulic or geotechnical condition along the slope:
Contracunetas (Intercepting Channels)
Trapezoidal concrete channels designed to intercept surface runoff at the top and intermediate levels of the slope, preventing uncontrolled flow and soil erosion.Canaletas en Banqueta (Bench Channels)
Secondary channels integrated into slope benches to safely guide water toward controlled discharge points.Derramaderos (Energy Dissipation Spillways)
Concrete spill structures designed to reduce flow velocity and safely transfer water between elevation changes without inducing scour or structural damage.
All elements were defined consistent with highway drainage durability requirements and maintenance expectations.
Design Logic & System Integration
Rather than treating each structure in isolation, the project was conceived as an integrated drainage system, where:
- Surface water is intercepted early
- Flow paths are clearly defined
- Energy is dissipated progressively
- Discharge points are controlled and reinforced
Our role focused on ensuring hydraulic continuity, geometric consistency, and constructability, particularly given the constrained access, steep terrain, and active roadway environment.
Technical Consulting Role
As consulting subcontractor, Tembok provided:
- Review and refinement of drainage geometry and sections
- Validation of concrete structural details and transitions
- Constructability input based on site conditions
- Technical coordination with the executing subcontractor
- Alignment with highway authority criteria and specifications
The emphasis was on reducing execution risk, avoiding ad-hoc solutions, and ensuring long-term performance of the drainage works.
Outcome
The resulting system provided effective slope drainage control, mitigating erosion risks and protecting roadway assets.
This project reflects Tembok’s ability to operate as a technical partner, contributing engineering clarity and execution-ready design within multi-party infrastructure projects.
