SUMMARY
One side of the production building subsided by 20 cm and needed strengthening to prevent further subsidence. The result of subsidence were cracks on the load-bearing walls and foundations. The first 4 meters deep down the ground under the concrete foundations consisted of sand and mud, which tended to self-seal due to the fact that the soils in construction pit were not properly compacted. At 4-8 meters below the foundation level, the ground conditions were more suitable for solutions to strengthen the foundation, since there was more solid clay present. In this area, the contractor URETEK designed a geopolymer and improved the ground conditions (created a mainland support) in order for the polymer columns to reach a good support and safely transmit the stresses from the concrete foundations. The project building stands on 10 concrete foundations (pillars). The ground base was reinforced as a result of the project to eliminate further subsidence and stop further damage to the structure.

TASK
URETEK reinforced the load-bearing structures of concrete foundations with 40cm x 4 m geopolymer columns. The columns were formed directly under the foundation to the depth of the support on a dense base.

APPLIED TECHNOLOGY
Geopolymer columns and Uretek deep injection.

RESULT
The ground was improved (reinforced) with 40 geopolymer columns (4 per foundation) and injections done up to a depth of 4-8 meters. The industrial building was strengthened without stopping operation and eviction.
