TECHNOLOGY
COLUMN INJECTION

Problem:

During the construction of 25m-long ground-cement columns, the existing pile foundation of the building experienced excessive technological subsidence.

Task:

Increasing the load-bearing capacity of the existing pile foundation in order to compensate for the resulting technological subsidence.

Method:

Deep injection (Column Injection)

Decision:

To solve this problem, the injection of a special deep composition of Uretek was prejected and used. The method of column injection along the side surface of each pile of the column foundation was chosen according to a special scheme. Full control of the injection process was provided throughout the entire length from th very depth levels in the on-line mode. The high adhesion and speed of solidification of the materials used made it possible to perform the task of increasing the load-bearing capacity of the existing pile foundation in a high quality and in a short time.
