Uretek is a great way to fill large voids quickly and economically. Historic sites can be sealed or filled against future opportunities to preserve them more fully; access ways can be closed semi-permanently; old pipes and storage chambers can be filled and decomissioned; and erosion in canal walls can be arrested.

Because Uretek can carry immense weights, voids under roads and railways, under ports or in mines are no problem at all, and best of all - as with all Uretek applications, the work can be done unobtrusively, and quickly, either during the day or during off peak hours.
