Rockfall Netting Protection Philippines

B&G Offers High Quality Rockfall Netting In The Philippines

​

Rockfall Netting and Debri Netting are highly specialized and precise engineered solutions.

You need a real partner for this - one who supplies high quality geotechnical systems and installs them using our own equipment and labor.

BrownN'Greenfield have installed many geotechnical systems using Rockfall and Debris Netting, from small-scale emergency repairs to whole stretches of highways in the mountains.

Rockfall Netting (RFM) is placed on geohazard slopes and vertical rock faces, holding-back passively or actively threats from falling boulders and rocks. They are an open-mesh structure, allowing free drainage and vegetation establishment. They can cover the whole rock surface under threat or just portions of it. The geohazard is reduced economically and for long periods of time.

Debris Ring Netting (DRN) is a vertical barrier installed in creeks and channels, usually up in the mountains, and looks like a tennis or badminton net, but actively traps boulders and rocks that get washed downstream during flash floods and typhoons. If you allow these boulders to move down the creek or river channel, they will scour and erode the banks and beds making problems downstream even more severe. These boulders and rocks need to be stopped and held-up in the mountains, so they cannot do severe damage below.

Manufactured from high-tensile galvanized steel, the RFN and DRN systems are anchored to the rock face or inside a creek or channel using Hilti-type anchor bolts and washers, using a precise drilling pattern into the rock face.

The rockfall netting hugs the rock surface, whereas the Debri Netting can also be removed and relocated, once the creek is full or choked- up -- making it especially economical compared to gabion walls or hollow block walls (which cannot be moved). 

Our Erosion Control Systems (for example ECOTex ECB) can be used with all the rockfall systems to make the slope green and in combination with hydro seeding directly on top.

Our specialized labor use cranes, hoist and ropes with harnesses to access the rock face and then drill directly for the anchor system.
