Enhance weak soils through the installation of compacted columns.

Utilize drop hammer compaction method to strengthen the soil.

Identify and utilize nearby granular soils for the process.

At Universal Foundation Company, we employ a method to enhance weak soils by installing densely compacted columns crafted from gravel or similar materials. Through this displacement process, we reinforce all soils within the treatment zone while also densifying surrounding granular soils.

​

Common uses

​

• It helps to reduce  foundation settlement

• Enhance bearing capacity to enable downsizing of footings.

• Boost stiffness for improved structural stability.

• Strengthen shear resistance.

• Lower permeability for better water resistance.

• Minimize liquefaction risks.

• Enable shallow footing installation in treated fills.

• Highly effective for sand compaction and land reclamation projects.

​

Process - The Top feed process

​

• Utilizing the drop hammer's weight, we compact the ground as the temporary casing tube reaches the intended depth.

• Stone is poured at ground level, surrounding the casing tube.

• The stone descends through the gap, filling the void around the casing tube.

• Lowering the drop hammer displaces the underlying stone, forming a dense column. This procedure repeats until a solid stone column is constructed to the surface level.

Advantages

Cheap

• Cost-effective solution.

• Versatile process adaptable to diverse soil and foundation needs.

• Depth capability up to 15 meters.

• Rapid execution facilitating swift progression to subsequent construction phases.

• Facilitation of standard shallow foundations, fostering cost efficiency.

• Utilization of recycled materials for environmental sustainability.

• Minimal noise and vibration for enhanced tranquility during construction.

Quality assurance

Our proprietary in-house quality production management software facilitates real-time data capture and analysis, validating the performance of ground improvement activities. Various production parameters are routinely recorded, such as depth, current, pull-down force, uplift/pull-down sequence, timestamp, and element number. Field trials supplement column production parameters verification, alongside static load tests, individual or group, compressive strength tests on column material, and diameter verification.
