Erosion phenomenon causing construction works stoppage was fixed thanks to Maccaferri’s BioMac products
Built by the South Korean shipbuilding company Hanjin Heavy Industries, the Subic Shipyard in the Philippines is the biggest shipyard ever built in the Country, and is known to be the fourth largest in the world.
During the construction works, some years ago, in order to make the development of the area possible, the project developers had to proceed with some cutting work of slopes, up to 40m-high, as well as the filling of some areas, which was especially required for the construction of access roads to the shipyard area.
Following heavy rainy seasons, an erosion phenomenon of exposed cut slopes occurred, which consequently resulted in damages to the property and construction works stoppage.
To find a solution to such challenging conditions, E.R. Sibulan Construction, the contractor in charge of the execution of the project, requested the assistance of Maccaferri Philippines Inc. to come up with a specialized recommendation from our part.
After an onsite exploration, we proposed an inexpensive erosion control mat made of 100% coconut fibers, known as BioMac C, combined with a hydro-seeding and adequate surface drainage system. Our BioMac C provided the necessary erosion protection for such application considering high rainfall, exposed slopes, strong water run-off and an erodible soil condition.
Indeed, Maccaferri’s BioMac C is capable of acting as a ground protector, seed protector and a moisture retention tool for vegetation, soil and root insulation and grass reinforcement, as it minimizes rain penetration. It is low-cost, light in weight, very convenient to handle and easy to install.
