Steel wire rockfall protection systems
Maccaferri DT Mesh is a core component of our MacRO rockfall mitigation and natural hazard protection application area. It is one out of a range of mesh systems that are selected according to our analysis of the project site conditions and client requirements.
Used for over 50 years, our DT Mesh is engineered from our double twisted hexagonal woven steel wire and is used as a drapery system to prevent rocks and debris from falling onto roads and railways. Due to the characteristics of the double twist, the steel wire mesh can withstand the punching force of falling rocks and without unraveling in the event of wire breakage.
DT Mesh is made from high quality steel wire, which is heavily galvanised to provide long term corrosion protection. An additional protective polymeric coating is also applied for meshes that are to be used in more aggressive environments, or where a longer design life is required.
Our DT mesh is manufactured in our factories around the world. In selected factories, the mesh is produced in compliance with CPR - Construction Product Regulation 305/2011, having EC marking in compliance with ETA-16/0758. The management and production system is certified in compliance with ISO 9001 and ISO 14001 (related to the environmental management system).

115 MWAC BARAS SOLAR POWER PLANT CHANNEL LINING SOLUTION
Philippines
Located in Pinugay, Baras Rizal, the vast area of the 115 MW Solar Power Plant being developed by Solenergy System Inc. is surrounded by mountainous terrain. Based on the hydrological data available, it is expected that a significant volume of runoff may flow towards the solar farm at peak rainfall conditions. The construction of open channel drainage canals is integral during the development of the facility to assure that peak discharge would be accommodated. For open channels, conventional drainage lining typically includes concrete-lined or earth-lined canals. Common problems with these options are that one could drastically increase project cost while the other could pose open channel instability like erosion, scouring, and undermining. Solenergy System Inc. is seeking a cost-effective alternative solution to traditional concrete lining while providing a structural sound structure.

Active Rockfall Protection in Borongan
Philippines
A slope collapse occurred in the area, creating immediate safety concerns for nearby infrastructure and road users. The instability of the slope increased the risk of falling debris and further soil movement, particularly during periods of rainfall. Without proper intervention, the affected area remained vulnerable to additional erosion and potential rockfall incidents, posing ongoing hazards and possible disruption to surrounding activities.

BEAVERNETTING EVERTSOORD
Netherlands
A thriving beaver population is threatening the stability of the Netherlands' sea defences. The Mammal Society has brought together other wildlife groups to work out how to protect these important water-blocking dykes from the small but potentially destructive semi-aquatic rodents. Beavers play an important ecological role in the Netherlands and were initially brought in to increase biodiversity. The beaver-breeding program began in 1988, and since then the beaver population has grown exponentially. There are now an estimated 700 beavers residing in the country's streams and canals. Triumphant mating habits combined with the beavers' ability to breed so successfully in the Dutch countryside mean they have been moving beyond the southern province of Limburg and entering towns and cities that may not be prepared for the influx. With the Dutch beaver population expected to hit around 7,000 by 2032, the need to take pre-emptive action is now a very important theme.
