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.
Plant fibers retain sediments but allow water to pass without clogging. Bermalonga® may be partially used as a deep drain.
The density of the plant fiber Bermalonga® is 100Kg/m3. It is easily handled, allowing manual transport to relatively inaccessible sites.
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.
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.
