Dear Sir or Madam,

This month we've added a new new Virtual Construction Site to the UNITRACC-Area "Learning" !

The new Virtual Construction Site gives a detailed description and explanation of the renovation of a defective sewer section consisting of concrete pipes DN 400 with a section length of 60 m by means of lining with spirally wound pipes. Even beneath the ground surface you won't miss a single detail of the process - thanks to the magnifier option and 3D-animation.*

Enjoy exploring the underground with UNITRACC.

Kind regards,

Dr.-Ing. Robert Stein
(UNITRACC Editor)

* From today the new Virtual Construction Site will be available for one week to logged-in users with at least a free-of-charge Guest-Package. Afterwards, you will need a Complete Package, for which you will be charged. You don't have a UNITRACC-log-in yet? Register here.
