To be a steel woven netting of hexagonal opening, which is used to prevent rocks and debris from falling to roads, railways and other structures.

It is unrolled over the slope and to be secured with anchor bolts, and rocks and debris will fall to the foot of the slope behind the netting drapery, which can be collected in trench of suitable dimensions.

Galvanized rockfall down netting made with high quality low-carbon steel wire to weave, steel wire tensile strength is 38kg/M2. The wire diameter may reach 2.0mm-4.0mm. And the galvanizing layer thickness can be made according to the customer’s request. Max. galvanizing quantity can be 300g/ M2.

PVC coated rockfall down netting made of PVC+ heavily zinc coated wires that offers longer service life and better anticorrosion property.

GABION

To be rectangular baskets fabricated from a hexagonal mesh of heavily galvanized steel wire. The baskets are filled with rock and stacked atop one another to form a gravity- type wall. Gabions depend mainly on the interlocking of the individual stones and rocks within the wire mesh for internal stability, and their mass or weight to resist hydraulic and earth forces. Gabions are a porous type of structure that can sometimes be vegetated. Gabions are considered to be a “hard” structural solution that has minimal habitat and aesthetic value.

Advantages: 

Ease of handling and transportation Speed of construction Flexibility (Gabions tolerate movement) Permeability to water (Good drainage) Gabions offer an easy-to-use method for decreasing water velocity and protecting slopes from erosion.

ROCK- MATTRESSES

The voids in the rockfill become progressively filled with silt, promoting vegetation growth which is essential to the preservation and maintenance of the ecological balance of the surrounding environment. The stone fill allows the water to seep through the structure while retaining the soil, therefore no additional drainage is required to relieve the hydrostatic pressures.
