Cover-type rock fall prevention nets utilize the friction of the wire mesh and the slope itself and the tension of the wire mesh to restrain rocks that have lost the force binding them to the slope.

Advantages

  • Cover the entire slope and guide falling rocks to the toe of the slope when installed on slope at risk of rock fall.
  • Lightweight components ensure easy installation.
  • Easy to repair.

Cable nets are a construction method that prevent rock falls by controlling the initial movement of rocks that are at risk of slipping by covering the slope in a lattice grid made from wire rope and securing each lattice point with an anchor.

NETIS Registration Number QS-090035-A

Advantages

  • Prevent rock fall by suppressing initial movement of rocks.
  • Clips installed at lattice points allow net to be installed without localized damage to wire ropes.
  • Lightweight components ensure easy installation on steep slopes.
  • Protects natural scenery and environment with little transformation of terrain.

SK thick nets are a construction method that prevents rock falls by suppressing the initial movement of rocks. Installing a thick net makes it harder for debris to escape and encourages natural vegetation.

NETIS Registration Number QS-090035-A

Advantages

  • Prevent rock fall by suppressing initial movement of rocks.
  • Clips installed at lattice points allow net to be installed without localized damage to wire ropes.
  • Lightweight components ensure easy installation on steep slopes.
  • Thick net is installed so that it hugs the slope closely, making it harder for debris to escape and encouraging natural vegetation.Application of vegetation base makes it possible to promote greenery.
