Slope Protection Structure for Botolan River, Zambales

Botolan in Zambales, Philippines is known for its wide grey sand beaches and proximity to an active stratovolcano, Mount Pinatubo. The eruption of Mount Pinatubo 3 decades ago, resulted in an excessive sediment yield that caused shoreline progradation. The process of progradation greatly silted the river channels which impeded the effectiveness of water flow. During heavy and persistent rainfall, the Bucao River can swell and overflow. This has proven to be detrimental to the communities that are in the area as residential homes, commercial buildings, roads, and vehicles would be rapidly engulfed by the rising waters and immediate emergency evacuation services will need to be enlisted to prevent the loss of lives.

To mitigate such occurrences from repeating themselves in the future, there are intentions to have the Bucao River dredged of the excessive sand sediments from its seabed. However, to ensure that the dredging process does not compromise the current integrity of the shoreline along the Bucao River, MHZ12-1 sheet piles have been deployed extensively to the perimeter of the shoreline. The MHZ12-1 sheet piles are engineered with tighter interlocks which provides greater water tightness. The thickened sections provide exemplary corrosion resistance which makes it perfect for application in seawater environments. It is designed to provide a greater strength-to-weight ratio to commonly used cold form sheet piles in the market. Coming in wider widths than regular sheet piles make it undeniably a more affordable solution and more efficient to implement as it is faster and easier to drive.
