BIODEGRADABLE EROSION MATS |
JUTE MAT
100% biodegradable organic jute fibres needle punched onto a hessian backing to form a blanket of mulch. Jutemat is recommended as a weed barrier, by preventing vegetation growth. It allows water and air to pass through allowing the soil to breathe which promotes the grow of desired plants. It also reduces water evaporation and has a light brown colour which blends in to most environments. |

JUTE MESH
100% biodegradable jute netting ideal for basic erosion protection but allowing growth of vegetation through its 20-30mm apertures. It is ideal for spray seed and spray bituminous applications such as slopes and swale drains |
|
COCONUT FIBRE MAT
100% coconut fibre matting suitable for preventing erosion but still allowing vegetation to grow through its matrix of needle punched fibres. It allows water and air to pass through allowing the soil to breathe which promotes the grow of all vegetation. It is brown in colour and blends in to most environments |

PERMANENT EROSION MATS |
TENAX MULTIMAT
The three-dimensional “gripping” TENAX MULTIMAT and TENAX MULTIMAT R geomats are purposely designed for the protection and planting of slopes subjected to surface erosion whenever a suitable vegetative substrate soil already exists. They have a thickness of about 20 mm and are manufactured by assembling and stitching together several layers of polypropylene (PP), extruded bioriented geogrids.
The process of molecular stretching, both in the longitudinal and transversal directions, considerably enhances the mechanical properties of the base polymer, thus providing a high tensile strength (minimum of 8 kN/m).
Geomats of this kind are composed of two layers of geogrid placed above and below a single central layer, mechanically folded so to give thickness and three-dimensionality to the geomat. The two flat geogrid layers confer a high tensile strength and allow for minimal elongation of the geomats. The dense folding of the central core limits the deformation of the geomat when filling with topsoil conferring it with optimal bearing strength.
The layers are held in place by mechanically stitching them together with a highly resistant polypropylene yarn during the manufacturing process. |

TERRAMAT 3D
TerraMat 3D is a synthetic turf reinforcement mat, which protects underlying soil from erosion and provides a reinforcing matrix for vegetative root growth. Its multi layered 3 dimensional structure and its flat, high modulus base layers, provides the following benefits:
1. Good contact with the existing surface
2. Tensite strength
3. Stiffness and dimensional stability to the soil surface
In addition the upper cuspated pockets provide the following benefits:
1. Reduces the impact of raindrops
2. Minimise the dislocation of soil particles
3. Reinforces the root system. |

GEOCELLS |
TENAX TENWEB geocells
TENAX TENWEB geocells are honeycomb shaped structures with a cell height ranging from 75 to 100 mm, made by the continuous extrusion of polyethylene (PE) and without any welding. The structure opens like an accordion and therefore can be transported and stored with minimal space and successively opened during installation, thus creating a series of completely interconnected, regular ovoid cells (diameter ranging from 100 to 300 mm).
Once expanded to its maximum extension and filled in with soil (or pea gravel, concrete, etc.) the structure becomes inextensible and monolithic, providing an effective means of confinement for unconsolidated materials lying within single cells and preventing their movement even on steep slopes, or also from substantial dragging forces such as those exerted by hydraulic currents. |
 |
The cellular structure is therefore particularly useful on arid, rocky or impermeable soils where vegetation is almost or totally lacking.
The structure’s junctions have a central opening through which water can pass so that effectively, all the cells are hydraulically interconnected: the geocells/soil composite structure attains good permeability, facilitates the absorption of water during precipitation, diminishes surface runoff and consequentially, erosion of meteorological origin.
Utilizing TENAX TENWEB geocells, it’s possible to confine on steep slopes a topsoil layer (up to 150 mm) allowing planting of the escarpment with high degree of confidence and success.
1. TENAX TENWEB geocells collapsed panels.
2. TENAX TENWEB geocells expanded panels.
3. The geocells filled with soil.
4. The cells are hydraulically connected; the structure facilitates water infiltration into the soil, thus reducing run-off and decreasing erosion.

BUNKERLINER |
BUNKERLINER
Bunkerliner is a three dimensional geogynthetic confinement system designed to reduce erosion of thin layers of sand on steep inclines and to allow the free passage of water while filtering fines. Constructed from UV Stable Black Polypropylene fibre needle punched on a reinforcing scrim. The scrin provides the stabiity to the Bunkerliner while the open matrix of the fibre placment, trap and stabilise the granules. |

TERRASTOP GABIONS |
TERRASTOP / PRODAC GABIONS & MATTRESSES
TerraStop / Prodac Gabions and Mattresses are heavily galvanized, hexagonally woven, steel-wire mesh boxes. Units are either zinc-galvanized or PVC-coated to ensure durability within the surrounding environment. Terrastop / Prodac Gabions and Mattresses create flexible, durable structures that resist erosive forces.
In addition, a more superior coating is also available in severe corrosive conditions such as in marine environments. The development of a Zinc - 5% Aluminium alloy known as Aluzinco® or Bezinal® is the next step in the fight against steel corrosion. This can also have an additional PVC-coating on the Aluzinco®/Bezinal® alloy for Ultimate Durability. |
