Ashapura Bentonite PILOGEL – Premium Sodium Bentonite for Piling & Drilling

Ashapura Bentonite PILOGEL is a specialized sodium bentonite product designed for piling, drilling, boring, diaphragm wall construction, and other demanding geotechnical and civil engineering applications. Bentonite is a naturally occurring clay material with a high content of swelling minerals, particularly montmorillonite. When mixed with water, sodium bentonite hydrates and expands to form a viscous suspension that can provide borehole stabilization, filtration control, and suspension of excavated soil particles.

PILOGEL is particularly suitable for projects where maintaining the stability of excavated boreholes is important, including deep foundation and bored piling operations.

What is Ashapura Bentonite PILOGEL?

Ashapura Bentonite PILOGEL is a sodium bentonite-based drilling and piling material supplied in powder form for preparation of bentonite slurry. Its principal functional mineral is montmorillonite, a swelling clay mineral that gives sodium bentonite its characteristic hydration and rheological properties.

When dispersed properly in clean water, the bentonite particles hydrate and form a stable slurry. This slurry can help maintain pressure against the walls of an excavation and create a filter cake on permeable soil formations, thereby helping reduce fluid loss.

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

Key Features and Benefits

Excellent Swelling Properties

Sodium bentonite has a strong affinity for water. When properly hydrated, it swells and produces a viscous slurry suitable for a variety of drilling and foundation applications.

Borehole Stabilization

During bored piling and drilling, bentonite slurry can provide support to the sides of the excavation. The hydrostatic pressure generated by the slurry can help reduce the risk of borehole instability under suitable ground conditions.

Filtration Control

Bentonite slurry can form a thin, relatively low-permeability filter cake along permeable borehole walls. This can help control fluid loss into surrounding soil and groundwater-bearing formations.

Soil Particle Suspension

The viscosity and gel characteristics of properly prepared bentonite slurry can help suspend fine excavated particles, supporting efficient removal and management of drilling spoil.

Suitable for Deep Foundation Work

Piling-grade bentonite is commonly used in bored pile construction, where stable borehole conditions are essential before reinforcement cage installation and concrete placement.

Major Applications

Ashapura Bentonite PILOGEL can be used in suitable applications including:

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

Application in Bored Piling

Bored piling is one of the most important applications for piling-grade bentonite. During drilling, boreholes may pass through loose soil, sand, gravel, fractured formations, or water-bearing layers. Such conditions can create challenges in maintaining borehole stability.

Bentonite slurry is introduced into the borehole to provide support to the excavation walls. The slurry can exert hydrostatic pressure and form a protective filter cake against the surrounding soil.

During drilling, the slurry can also help suspend fine soil particles generated by excavation. Before concreting, the slurry should be properly managed and tested according to the approved construction method and applicable project specifications.

Bentonite Slurry Preparation

Correct slurry preparation is essential for achieving the desired performance.

PILOGEL powder should be gradually added to clean water under suitable mixing conditions. Controlled addition and adequate mixing help prevent the formation of lumps and promote uniform hydration.

After mixing, the slurry may require sufficient hydration time to develop its required viscosity and other rheological properties. Hydration time can vary depending on water quality, temperature, mixing efficiency, bentonite concentration, and product characteristics.

The required dosage should not be assumed to be identical for every project. It should be established through laboratory testing, field trials, or the project’s approved slurry management procedure.

Important Slurry Parameters

For piling and drilling operations, the following parameters may be monitored:

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

Regular testing helps determine whether the slurry remains suitable for the relevant stage of construction.

Technical Quality Considerations

When selecting Ashapura Bentonite PILOGEL or another piling-grade bentonite, buyers may consider:

• Montmorillonite content
• Swelling capacity
• Viscosity
• Fluid-loss characteristics
• Moisture content
• Particle size
• Yield
• Gel strength
• Chemical composition
• Slurry performance

For commercial projects, technical documentation such as Technical Data Sheet (TDS), Certificate of Analysis (COA), and applicable quality certificates should be reviewed where required.

Storage and Handling

PILOGEL should be stored in a dry, covered, and clean warehouse. Bags should remain sealed and protected from moisture until use because premature hydration can affect handling and product quality.

The product should be protected from contamination and excessive humidity. During handling and mixing, suitable personal protective equipment should be used in accordance with the manufacturer’s Safety Data Sheet.

Proper stacking and stock rotation are recommended to maintain consistent product quality.

Why Use Ashapura Bentonite PILOGEL?

A suitable piling-grade sodium bentonite can support efficient borehole management by providing swelling, viscosity, filtration control, and suspension characteristics required for many drilling and foundation applications.

However, bentonite performance is influenced by the entire slurry system and construction process. Soil conditions, groundwater, drilling technique, slurry concentration, mixing, hydration, desanding, slurry testing, reinforcement installation, and concreting procedures all play important roles in successful piling operations.
