Abweb TRP - Geocells

The Abweb TRP system is a no dig solution preventing damage to the tree root structure during the installation process. Abweb TRP is quick and easy to install, reduces construction time and in many instances greatly reduces the depth of imported stone required saving time and money and reducing the environmental impact of the project.

Abweb TRP is geocell mattress which is expanded on site and then filled with a clean no-fines stone; the strength of the system comes from the containment of the stone within the structure although unlike traditional construction this is achieved without compacting the stone and the subsequent loss of permeability. It is manufactured from strips of high density polyethylene HDPE cross welded to form cells, the strips can be perforated if required to allow the lateral movement of air and water through the structure.

The porous surface also ensures water and air can carry essential nutrients to the tree roots. Beneath the Abweb TRP is a non-woven geotextile positioned to prevent any fines washing through and ultimately clogging the system thereby preventing the water and air from reaching the roots over the life time of the tree.

Many pavement finishes are suitable for use over Abweb TRP including porous asphalt and porous block paving. In temporary applications there is usually no requirement for a pavement finish, the fill of the Abweb TRP acting as the surface.Abweb TRP can be used in both permanent and temporary pavement constructions. In temporary constructions the system can be removed without damaging the roots once operations on site are complete.
