Bentonite for Trench Cut-Off Walls and Containment Barriers
Trench cut-off walls and pond linings are essential in seepage control, groundwater protection, and containment applications. These systems create low-permeability barriers that prevent water migration in dams, canals, landfills, and containment ponds.
VodaSeal SCB’s exceptional swelling and sealing properties make it ideal for forming impermeable barriers in soil.
Natural Hydraulic Barrier Bentonite
High-swelling natural bentonite, free of synthetic polymer, that forms a semi-solid gel-like mass on contact with water — for cut-off wall, dam and pond-lining barriers.

Sourced and Processed for Export-Grade Consistency
VodaSeal™ SCB is processed from Amrfeo’s own Kutch, Gujarat bentonite reserves under ISO 9001:2015 quality systems, with Star Export House-backed logistics from Mundra and Kandla ports. For geotechnical contractors and cut-off wall specifiers sourcing hydraulic-barrier bentonite internationally, that means a traceable, quality-controlled supply chain rather than a variable commodity spot-buy.
Frequently Asked Questions
VodaSeal™ SCB is a natural, polymer-free bentonite used to form the hydraulic barrier in soil-cement-bentonite (SCB) trench mixes — for cut-off walls, dam lining and pond lining wherever seepage control is required.
The granule (graded lump) form is easier to dose and mixes with less dust on trenching rigs, settling to a permeability as low as 4.9×10⁻¹⁰ m/sec; the powder form disperses and hydrates faster (99% min passing 100 mesh) for plants set up for fine bentonite handling. Choice depends on your mixing plant, not the barrier performance target.
As low as 4.9×10⁻¹⁰ m/sec in granule form after settling — among the tightest hydraulic barriers achievable with an unmodified natural bentonite.
No. VodaSeal™ SCB is a natural, polymer-free bentonite, so the finished barrier is a purely mineral montmorillonite seal — relevant where a project specification excludes synthetic additives.
Free swelling of 24–30 ml and methylene blue adsorption of 390–400 mg/g, indicating high montmorillonite content and reliable gel-forming performance in both fresh and moderately hard water.
