Maccaferri® Mineral Terramesh® wire mesh is a modular soil reinforcement system used to form a steep soil structure with a rock-face finish, facing at angles of up to 87 degrees. It consists of prefabricated units of Galmac® and PoliMac® coated double-twist "DT" wire mesh to form an inclined front face and an extended integral base referred to as the reinforced tail section.
The system is ideal for use where a contemporary, clean-faced aesthetic finish is preferred, the inclusion of galvanised steel mesh frame delivers clean uniform lines with selected stone fill forming a thin layer as the facade.
Mineral Terramesh provides an effective solution for reinstating slips and dropouts, steep slopes and bridge approach ramp.

WHY CHOOSE MACCAFERRI MINERAL TERRAMESH?
- Durable structure coated with Galmac and PoliMac provides a design life of 120 years under most severe environmental conditions
- Used for structures up to 3m high without geogrid reinforcement and over 70m high with geogrid
- Improved performance compared to welded mesh facings due to the greater connection capacity provided by its integral mesh tail which avoids the need to provide a geogrid wrap to the facing unit
- Quick and simple installation with no connection required between geogrid and the assembled unit
- Savings in material costs by reducing the amount of imported material required due to less facing stone which does not require ongoing maintenance and using site-won fill as backfill for <70° structures
- Independently verified and tested with BBA-HAPAS certification
- Design support including access to an advanced suite of software free to our clients and on-going in-house training or via seminars
- Supported with specialist installation tools for hire including pneumatic lacing tools or you can purchase "C" rings, lacing wire and preformed bracing wires that help to halve assembly time

FUNCTION
Erosion & Sediment Control
The use of a geosynthetic to prevent soil or other particle movements on the surface slope. Acts to reduce soil erosion caused by wind forces, rainfall impact and surface water runoff. The use of geosynthetics in erosion control is to maintain soil cover either as a temporary measure offering protection from soil loss whilst vegetation is established or as a permanent control measure, typically on steeper slopes or high-water velocity situations.
Reinforcement
Geosynthetics provides additional strength to soils and aggregate. Used to reinforce steep slopes, and to stabilise road or rail construction over weak and variable soils. Enables embankments to be constructed over very soft foundations and to build slopes at steeper angles than would be possible with unreinforced soil. Geosynthetics (or geogrids) are also used to bridge over voids that may develop below load bearing granular layers (roads and railways) or below cover systems in landfill applications.
Retaining
Geosynthetic or geogrid acts to support soil laterally so that the structure can be retained at different levels on the two sides. Retain (holds back) any material (usually earth) and prevents it from sliding or eroding away. Gravity retaining and reinforced soil retaining walls are designed to resist the material pressure of the material that it is holding back.
