Universal Foundation Company utilizes dynamic compaction, which entails strategically dropping a 2-tonne crane-hoisted weight in a predetermined grid pattern to enhance loose, granular, and mixed soils and fills.

​

Common uses

​

• Enhance bearing capacity.

• Minimize settlement.

• Address liquefaction risks effectively.

• Opt for solutions that bypass significant below-ground obstacles.

​

Process

​

Universal Foundation Company employs dynamic compaction as a method for enhancing ground stability. This technique involves utilizing a heavy steel and concrete weight, typically weighing between 10 and 12 tonnes, which is dropped from heights of up to 5 meters in free fall. The ground is repeatedly compacted through surface tamping in a grid pattern over the site, forming a pass. Depending on soil type and condition, two or three passes may be necessary. Granular material is used to fill in the imprints left at each drop position after each pass.

​

Advantages

​

• Proficient in consolidating diverse types of fragile soils

• Enhanced load-bearing capabilities

• Diminished settling tendencies

• Sustainable approach minimizing reliance on imported materials

• Universal Foundation Company has enhanced soil conditions on marginal sites to enable the utilization of shallow foundations without the need for deep excavation or piling.

Quality assurance

​

Universal Foundation Company typically conducts in situ testing using boreholes or static cone penetrometers, coupled with measurement of print volume and site surface settlement, during dynamic deep compaction operations. The treatment approach, energy level, pass count, and sequencing must be tailored considering soil conditions, development type, and desired bearing capacity and settlement characteristics. A comprehensive understanding of soil conditions before treatment and meticulous control throughout all phases of work is crucial. Universal Foundation Company also typically integrates in situ testing via boreholes or static cone penetrometers, along with print volume measurement and site surface settlement monitoring, within the dynamic deep compaction contract.
