Gabions Philippines

Gabion Engineering Philippines

Brown N' Greenfield supply and install galvanized steel wire mesh and welded gabions and gabion mattresses for flood defense - whether in creeks, on riverbanks, or marine and coastal applications.

This is a traditional and well-documented method of flood defense. It can be fast, and structures can form a regular shape along a river bank whilst still being free-draining. They are easily modified and repaired, and labor is easily trained.

For more severe environments, the gabion baskets can also be supplied with a robust PVC polymer coating.

Gabion standard sizes are based on cubic meters - for example 1m x 1m x 1m, 2m x 1m x 1m.

Gabion mattresses are often used in front of gabion flood defenses and underneath them, to provide scour protection and enhance the foundation. They are typically 0.5 to 1m thick and extend beyond the toe of the main gabion wall by several meters. 

B&G conveniently supply and deliver gabions flat-packed with tire-wire. Our labor can be arranged or we can arrange training on their fabrication and erection.

Gabions can be filled with local or trucked-in boulders and rock. Filling is best done by hand and occasionally assisted with mechanical-filling using backhoes. Filling by B&G assures the boulders inside the gabion are tightly-packed to give the maximum structural density, flood defense integrity, and performance. 

The best gabion and mattress systems are filled such that the finished gabion wall is straight and aligned, without gaps or bulging of the front face. 

Therefore, with proper installation of gabions, this integrity feature is maintained throughout the life of the flood defense. 

Allowance can be made for drainage pipes, sewer outfalls, etc. in the gabion design and construction.

Design of a gabion flood defense system includes geotechnical stability analysis. 

Structures up to 50m high can be with gabions and their extent can run for for many kilometers.

A small team of laborers and equipment are required.

BrownN'Greenfield's Hi-Ten geotextiles are also supplied as filter cloth to provide drainage and separation underneath and behind the gabion system.

If boulders are in short supply , B&G's Bastion Gabions are the perfect alternative, filled with sand or silt.
