Glossary of Terms

Capacity - Tube capacity is measured in volume, not weight like tons. Use the tube capacity chart to determine capacity of gallons or CY per linear foot.

Bags - Tubes

Diameter - There is no diameter measurement used with tubes.

Dredging Job - An application that uses a dredge and tube for dewatering. The specifications are written on the dredging, not the tubes. This is more common and much easier than a tube job. The tubes are replacing an open settling pond or a mechanical dewatering process. The spec that is sometimes hard to meet on these jobs is the ppm suspended solids on run off water from the tubes (TSS).

Fill Ports - The openings in the tube with sleeves attached for inserting the fill pipe.

Final Gross Capacity - The final fill capacity of the tube after the shrinkage of the fill material and multiple pumpings and dewaterings will be very different from the in situ measurements of the job. The more times the tube is filled and the more time that is allowed, the more the tube will hold.

Hanging Bag - A small (feed sack size) geotextile bag open on the top with seat belt handles sewn on for hanging. This bag is used to determine the shrinkage and some of the dewatering characteristics of the fill material.

Height - The measurement of the tube from the ground it is resting on to the top of the tube. This measurement is important to determine capacity and the pressure load on the tube.

Polyester - The white tubes. Very strong and durable. Used mostly for structure.

Polypropylene - The black tubes. Used mostly for dewatering. Less expensive and release water better than polyester.

Socks - Tubes

TSS - Total Suspended Solids

Tube - Geotextile fabric sewn into a closed shape to receive slurry, contain the solids and release the water.

Tube Job - An application that uses tubes in a structural manner. The tubes stay in place and the specifications are written on the placing and size and shape of the tubes.
