MacMat HS
Reinforced geomat for slope stabilization
MacMat HS is the next-generation of high performance geomats, combining a three-dimensional matrix polymeric geomat reinforced with Maccaferri’s Steelgrid system. It is used for demanding slope face stabilisation applications which require a combination of erosion protection and superficial stabilisation.
The reinforcing hexagonal steel wire mesh has mechanical performance characteristics that exceed those recommended in EN 10223-3. The wire is heavily galvanised with Zn-Al5% in accordance with 10244-2, Class A.
The galvanised wire and reinforcing cables are also available with an additional polymeric coating. Mechanical performance of the product (tensile strength, puncture resistance) is the same as Maccaferri Steelgrid.

NANJUNG TUNNEL EROSION CONTROL
Indonesia
Nanjung Tunnel Project is located in Bandung, West Java, Indonesia. This tunnel is built to facilitate the flow of the Citarum River, so that it can overcome the flooding in Bandung. The operation of the Tunnel is intended to reduce the flooded area from the initial 490 hectares to 80 hectares. The surrounding slopes around the tunnel need to be protected from the potential erosion. The slope which is mainly composed of fine-grained soil required protection from erosion created by rain and surface water flow. The selection of the right solution is necessary in order to prevent failure by the presence of water. Erosion Control Solution by Maccaferri Indonesia was selected considering its ability to allow surface seepage and to grow vegetation (LCC – Legume Cover Crop).

RIVER BANK PROTECTION AT CITRAGRAN CIBUBUR
Indonesia
Ciputra, one of the biggest property developers in Indonesia, faced erosion issues for one of their new projects in Cibubur, West Java. Located not so far from the river, Ciputra wanted to protect the access road from erosion and build the slope protection before the landslide come off and harm the area due to the combined action of the water flow causing the erosion of the slope and the heavy rainfalls saturating the clay soil of the slope, furthermore progressive road failure was occurring. Rapid countermeasures to guarantee the safety of the housing area were mandatory.

SINDANGHEULA DAM
Indonesia
Sindangheula Dam Project is located in Serang, Banten, Indonesia. The dam with a capacity of 9. 26 million m3 is a National Strategic Project (PSN) which was built to anticipate the increasing demand for domestic and industrial raw water in Serang District, Serang City and Cilegon City by supplying 800 liters / second raw water. The surrounding slopes around the dam need to be protected from potential erosion. The slope which has the sandy-clay type of soil required protection from erosion created by rain and surface water flow. The selection of the right solution is necessary in order to prevent failure by the presence of water. Erosion Control Solution by Maccaferri Indonesia was selected considering its ability to allow surface seepage and to grow vegetation (LCC – Legume Cover Crop).
