The Davao City coastal road bypass project aims to alleviate traffic congestion in the city by constructing a road from Roxas Avenue to Bago Aplaya, passing through NHA Kadayawan Homes, Matina Aplaya, and Bolton Isla. Three roundabouts will be installed along the 35 km (21.7 mile) coastal stretch at Roxas Avenue, Times Beach area, and Matina Aplaya.
Due to the region's growing population and ongoing development, traffic congestion on major roads has become a significant problem. The coastal road project aimed to address this issue.
In the Bago-Aplaya Section facing Davao Gulf towards Talomo, an elevated highway with a 90-degree vertical slope on both sides, the contractor needed to stabilize and reinforce the embankments effectively.
For this project, a segmental block wall reinforced with MIRAGRID® GX geogrid was chosen. This design offers fast, durable construction. MIRAGRID GX geogrid possesses the necessary properties for long-term reinforcement, including high tensile strength at low elongation, minimal creep, and low installation damage. Its superior interlocking mechanism and connection capacity to block wall systems make it an ideal choice.
Construction:
The reinforced segmental block wall system involved the use of precast concrete blocks arranged to form the wall facing. The soil/sand backfill behind the wall was reinforced with MIRAGRID GX geogrid. The blocks were designed with an interlocking mechanism that securely connected them. The geogrid reinforcement was placed horizontally on the soil backfill and connected to the concrete blocks at specific design heights of the wall.
Performance:
By utilizing MIRAGRID GX, the construction of the reinforced segmental block wall system resulted in a relatively flexible structure capable of accommodating differential settlement without causing damage. The project successfully achieved the goals of stabilization and reinforcement, while also being completed within the designated time and cost parameters.

Subgrade stabilization in Santa Ana parking lot with MIRAFI RSi
MIRAFI® RS380i was used in a Santa Ana College parking lot expansion to reduce pavement thickness, avoid utility conflicts, accelerate construction, and improve long-term pavement durability.
Utilizing MIRAFI HP570 and MIRAGRID 7XT for efficient development
Rock County, Minnesota, replaced a closed timber bridge using the GRS-IBS system with MIRAFI® 7XT and MIRAFI HP570. These provided reinforcement, enabling rapid, cost-effective construction without deep foundations.
