Rehabilitating Soils to Increase the Bearing Capacity Under Milk Storage and Grain Handling Facilities

By Robert Armstead

Silos are storage systems designed to contain massive amounts of weight within a concentrated area and vary in size, ranging from 20-80 feet tall with diameters of 12-30 feet. Some storage facilities have more than one or two silos sitting in a small area.  When the silos are full, the significant weight can impact settlement of the foundation and/or the foundations of nearby structures.

In addition to the consolidated weight of tanks that hold liquid and grain storage bins, the surrounding processing facilities get a lot of traffic as well. There is a constant stream of trucks, mostly loaded with heavy cargo, coming and going from the facility. When there is a rail spur next to the facility, the soils underneath and around the grain bins, silos, and mission critical buildings are taxed with even more weight.  Consequently, there is a lot of weight consolidated into a relatively small area around these crucial, very busy facilities.

After heavy rainfall like…

URETEK Stabilizes Flex Space Footings and Walls

By Robert Armstead

Flex space buildings can run as large as 60,000 square feet, or more.  What makes them unique is the ability to move walls and change the configuration of the space based on a tenant’s needs. When weak bearing soils cause footing and slab settlement, it can create structural problems interfering with the tenant’s operations.

This is what happened at the JLL Townpark warehouse in Kennesaw, GA. When the vinyl composition tile (VCT) began to pop off the floor, causing trip hazards, and the ceiling grid buckled and ceiling tiles began to fall, URETEK Holdings was called in to analyze the cause and propose a repair for the least invasive method for stabilizing the soils supporting the building.

Stabilizing Concrete Slab Settlement

By uretekhr

Recently, URETEK was called in to stabilize one of Brevard County’s lift stations.

The objective was to prevent further movement of the soil and lift the slab to its original position.

The problem was poorly compacted soil and a sodium hydroxide leak, which the station uses to combat odor, that caused the slab that the generator rests on and an exterior concrete slab to settle, which was now compromising the integrity of the building.

The solution was to inject URETEK’s 486STAR material, at various locations and depths, under both the interior and exterior slabs and the compromised exterior walls, in order to stabilize the soils.

URETEK was able to perform all of the work in one day without interfering with the operation of the lift station.
