Description

Geotube is a large size of tube shaped bag sewn by high strength of woven geotextile. The size of geotube can be varied according to the project requirement, which the maximum length is up to tens of meters. The primary application is in the construction of diking project. And nowadays, the the application scope are becoming more extensive. For instance: river dredging, lake desilting, environmental protection,etc.

If the required specification is between the neighboring specifications of the data table, interpolation method can be used for calculating the technical parameter. If the specification is beyond the specification scope in the table, the technical data will be determined by negotiation of the two business parties.
