TerraDrain can be of significant assistance in increasing the speed of consolidation of very soft soils.

This ultimately improves the shear strength of the soil so that an engineered structure may be constructed quickly.

TerraDrain is a specially designed polypropylene core extruded into a unique configuration to transmit maximum water flow on both sides of the core.

The core is fully wrapped in a non-woven geotextile filter that is ultrasonically welded to maintain effective filtration. The main design advantage of this core structure is the resistance to pinching off flow when distorted under the effects of ground consolidation.
