Ashapura Bentonite PILOGEL – Premium Sodium Bentonite for Piling, Drilling & Boring

Ashapura Bentonite PILOGEL is a high-quality sodium bentonite specially developed for demanding piling, drilling, boring, foundation, and civil engineering applications. Produced from naturally occurring bentonite clay with a high content of swelling clay minerals, PILOGEL is designed to provide effective viscosity, suspension, filtration control, and borehole stability during construction and drilling operations.

Bentonite slurry plays an important role in maintaining the stability of excavated boreholes and trenches by forming a protective filter cake along the surrounding soil. This helps reduce fluid loss and supports the integrity of the excavation during piling and foundation construction.

What is Bentonite PILOGEL?

PILOGEL is a specialized bentonite product used to prepare drilling and piling slurry. When properly dispersed in water, sodium bentonite hydrates and swells, producing a viscous suspension.

The resulting bentonite slurry can help stabilize borehole walls, suspend excavated soil particles, and control the movement of groundwater into the excavation. These properties make it particularly useful for bored piling and other deep-foundation construction methods.

The actual performance of bentonite slurry depends on the product grade, water quality, soil conditions, mixing procedure, slurry concentration, hydration time, and project requirements.

Key Features and Benefits

Excellent Swelling and Hydration

Sodium bentonite has a strong ability to absorb water and swell. When properly hydrated, it produces a stable slurry suitable for piling and drilling applications.

Borehole Stabilization

Bentonite slurry helps create hydrostatic pressure within the borehole and can form a protective filter cake on the surrounding soil. This helps reduce the risk of borehole collapse in suitable ground conditions.

Filtration Control

A properly prepared bentonite slurry can reduce fluid loss into permeable formations by forming a relatively low-permeability filter cake along the borehole wall.

Suspension of Soil Particles

The viscosity of bentonite slurry helps keep fine excavated particles suspended, supporting their removal and improving slurry management during drilling operations.

Reliable Piling Performance

Properly selected and prepared bentonite can contribute to stable borehole conditions and efficient foundation construction, particularly in bored piling projects where maintaining excavation stability is critical.

Major Applications

Ashapura Bentonite PILOGEL is suitable for applications including:

• Bored piling
• Deep foundation construction
• Rotary drilling
• Drilling and boring
• Diaphragm wall construction
• Trench excavation
• Soil stabilization
• Geotechnical drilling
• Civil engineering projects
• Foundation investigation
• Selected tunneling and underground construction applications

Application in Bored Piling

Bored piling is one of the most important applications of piling-grade bentonite. During drilling, the excavation may encounter loose, sandy, fractured, or water-bearing soil conditions.

A properly prepared bentonite slurry can be introduced into the borehole to provide support to the excavation walls. The slurry exerts pressure against the surrounding formation and helps reduce the inflow of groundwater.

As drilling progresses, the slurry also helps suspend fine soil particles generated during excavation. Before concreting, the slurry should be properly conditioned and managed according to the approved piling method and project specification.

Slurry Preparation

Proper preparation is essential to achieve the desired performance from PILOGEL.

The bentonite powder should be gradually dispersed into clean water under suitable mixing conditions. Adequate mixing is necessary to prevent lump formation and promote uniform hydration.

After mixing, the slurry may require sufficient hydration time before reaching its desired rheological properties. Water quality, temperature, mixing equipment, concentration, and hydration time can all influence the final slurry performance.

The required dosage should be established through laboratory or field trials based on actual soil and groundwater conditions rather than relying on a single universal dosage.

Important Slurry Properties

For piling and drilling applications, important slurry parameters may include:

• Density
• Marsh funnel viscosity
• pH
• Fluid loss
• Gel strength
• Sand content
• Filter cake characteristics
• Yield and rheological properties

These parameters should be monitored during construction according to the project specification and applicable engineering standards.

Quality and Grade Selection

The appropriate bentonite grade should be selected according to the application and required slurry performance.

For demanding piling and drilling projects, factors such as swelling capacity, viscosity, filtration characteristics, moisture content, particle size, and chemical composition should be considered.

Where required, technical documentation such as TDS, COA, and relevant quality certificates should be reviewed before procurement and use.

Storage and Handling

Ashapura Bentonite PILOGEL should be stored in a dry and covered area away from moisture. Bags should remain properly sealed until use to prevent premature hydration and contamination.

During handling, avoid unnecessary exposure to moisture and excessive dust. Suitable personal protective equipment should be used according to the product’s Safety Data Sheet.

Proper stacking and warehouse management are also important to maintain product quality during long-term storage.

Why Use Piling-Grade Sodium Bentonite?

The use of a suitable piling-grade sodium bentonite can provide several practical advantages during deep-foundation construction. It can help maintain borehole stability, control filtration, suspend soil particles, and support efficient drilling operations.

However, bentonite is only one component of the overall piling system. Successful performance also depends on proper borehole design, slurry preparation, soil conditions, groundwater conditions, drilling technique, desanding, slurry testing, and concreting procedures.

Conclusion

Ashapura Bentonite PILOGEL is a specialized sodium bentonite solution for piling, drilling, boring, and deep-foundation applications. Its swelling, viscosity, suspension, and filtration-control properties make it suitable for preparing bentonite slurry used to support borehole stability and manage excavated material.

For optimum performance, PILOGEL should be prepared and tested according to the specific project requirements, soil conditions, groundwater conditions, and applicable construction standards. Proper storage, mixing, hydration, slurry monitoring, and site management are essential for achieving consistent results in piling and drilling operations.
