Apparently Insurance companies have used Uretek to endeavour to relevel concrete slabs in Christchurch.  I am aware of situations where the use of Uretek has failed to achieve the required re-level.   Court proceedings are likely to be issued shortly.  Any people that have had bad experiences with insurance companies and Uretek are welcome to contact me and maybe become a part of a group.  You can contact me on 027 434 5489 or
