SEDIMENT RETAINERS

Bermalonga
Bermalonga® was developed by Deflor and has been successfully used in engineering works. It is composed of pressed dehydrated plant fibers forming an extremely strong and flexible cylinder.

Technical specification:

Drainability
Plant fibers retain sediments but allow water to pass without clogging. Bermalonga® may be partially used as a deep drain.

Light
The density of the plant fiber Bermalonga® is 100Kg/m3. It is easily handled, allowing manual transport to relatively inaccessible sites.

Moisture retaining
Bermalonga® can greatly retain moisture, absorbing about five times its weight in water. A typical 40 cm-diameter, 1.60 meter-length Bermalonga® weighing 20 kg absorbs up to 100 liters of water.

Flexible
Easily molded on the site, allowing bending and curves. Volume is reduced when pressed.

Bermalonga® is manufactured in 20, 30, 40 and 50 cm diameters. The standard length is 1.60m, extensible to 10m with no loss of its characteristics.
