Stopping the subsidence of the road surface on the rise of Tallinn Song Field, filling voids and stabilizing the soil

IN BRIEF

Pipeline was installed under a busy road in Tallinn, but the soil surrounding it was not sufficiently compacted, which caused subsidence of road surface. Subsidence has reached the point where it started to disturb traffic and after two to three attempts to fix it, the client contacted URETEK team.

TECHNOLOGY USED

Filling voids by using traditional excavation method would have caused stopping traffic for four days. Considering that it is a busy street, such a solution would have been extremely disturbing for road users. By using URETEK method, this problem was solved by closing one lane for just four hours.

RESULT

In the course of this task, special geopolymer was injected directly in problem area and filled voids. After filling voids, the client replaced topmost soil layer with asphalt and street was reopened for traffic. Client saved both time and money by using URETEK technology.
