Industrial Facility, Zabaykalsky Krai, Russia
OBJECTIVE
Mitigation of adverse properties of Type II collapsible (subsiding) soils.
TECHNOLOGY
Integrated ground improvement solution combining jet grouting and soil strengthening in controlled hydrofracturing mode using the PolyJET® injection method.
MATERIALS
DESCRIPTION
As part of a facility expansion project, foundations were required for process equipment imposing a design load of 40 tonnes per square meter.
The site was characterized by collapsible soils (loess-type subsiding soils) with a thickness of approximately 16 meters, presenting a high risk of differential settlement under load.
RESULTS
A geotechnical calculation model and engineered design solution were developed.
The solution was implemented in two stages:
As a result, stable foundation performance under operational loads was achieved, and the industrial structures were successfully constructed.

RESULTS
A geotechnical calculation model and engineered design solution were developed.
The solution was implemented in two stages:
- Installation of jet grouting columns (jet piles);
- Soil improvement by injection using the PolyJET® controlled hydrofracturing method.
As a result, stable foundation performance under operational loads was achieved, and the industrial structures were successfully constructed.
