Bastion Engineering Philippines

BrownN'Greenfield supply and install galvanized steel wire mesh and welded B&GStion Bastion Gabions and Bastion Gabion Mattresses for flood defense - whether within creeks, on riverbank, or for marine and coastal applications.

B&GStion Bastions differ from standard gabions as they can be filled with silt, sand & gravel (if there is a local shortage of boulders).

They are line with special Hi-Ten geotextile as part of the system.

This is a beneficial modification of the gabions 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.

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

Bastion gabion standard sizes are based on cubic meters - for example, 1m x 1m x1m, 2m x 1m x1m.

Bastion Gabion Mattresses are often used in front of flood defenses and underneath them, to provide scour protection and enhance the foundation. They are typically 0.5m to 1m thick and extend-out from the toe by several meters.

B&G conveniently supply and deliver Bastion Gabions flat-packed with tire-wire. Labor can be arranged or training on their fabrication and erection.

B&GStion filling is best done by using a slurry pump and occasionally mechanically-filled using backhoes. Filling by B&G assures the sand & gravel inside the Bastion Gabion is compacted and consolidated to give the maximum structural density, flood defense integrity, and performance.

The best Bastion Gabion and Mattress systems are filled such that the finished wall is straight and aligned, without gaps or bulging from the front face.

To maintain drainage one-in-ten (10%) of Bastion Gabions can be replaced with a traditional Gabion, with Hi-Ten geotextile filter behind.

Therefore, with proper installation of Bastion 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.

Geotechnical design of Bastion Gabion flood defense system includes stability analysis.

Structures up to 50 meters high can be built with Bastion Gabions and their extent can run for many kilometers.

Only a small team of laborers are required.
