Micro Tunnelling Bentonite

Bentonite has excellent thixotropic /suspension properties with low filtrate loss which makes it ideal for piling & drilling applications. Thixotropic nature of Bentonite allows slurry to penetrate deep into cleavages cracks and clogs the pores and develops good suspensions and friction agent stabilizing the excavations.

We manufacture High yield Bentonite as per Indian Standards (IS), American Petroleum Institute (API) and Oil Companies Material Association (OCMA) Standards.

Benefits

• Slurry Formation: Bentonite is used to create a stable slurry for micro- tunnelling, providing support and lubrication during excavation.
• Excavation Support: The bentonite slurry exerts hydrostatic pressure, preventing collapse of the tunnel face and stabilizing the excavation.
• Cuttings Suspension: It helps suspend and transport drill cuttings away from the cutting face, maintaining a clear path for the tunnel boring machine.
• Sealing Properties: Bentonite's swelling ability forms a seal around the tunnel walls, preventing water ingress and maintaining stability.
• Lubrication: It reduces friction between the tunnel boring machine and the surrounding soil, facilitating smooth advancement of the tunnel.
• Density Control: Bentonite assists in controlling the density of the slurry, ensuring it provides adequate support and stability for the micro tunnelling operation.
• Packaging – 25 kg, 50 kg, 1mt Bags or customized packing as per requirement.
