Construction & Civil Engineering

Bentonite in civil engineering applications is traditionally used as a thixotropic, support and lubricant agent in diaphragm walls and foundations, in tunnelling, in horizontal directional drilling (HDD) and pipe jacking. Bentonite, due to its viscosity and plasticity, is also used in Portland cement and mortars.

The recognition of bentonite as a vital construction element is still in its latent stage, since a hefty percentage of foundations and other civil engineering activities are still carried out without using bentonite and are incurring much higher expenditure through use of cast iron of steel liners. The awareness regarding the use of bentonite in the civil engineering industry has yet to go a long way.

Bentonite finds its use construction mostly in a fluidic (commonly called as bentonite slurry) form because of its rheological characteristics (i.e. their behavior as bentonite slurries when mixed with water).

Advantages of Our Products

  • Attains optimum green strength in minimum time.
  • Gives clean finish to castings.
  • Due to thermal stability less destruction in bentonite i.e less consumption.

Civil & Construction Bentonites

bentonite for land fill applications

BW-Pilling

BW-PILLING is widely accepted by civil construction industries for stabilization of slopes during excavation in unstable grounds as well as land fill applications.

  • BW-PILLING is a Natural Sodium Bentonite.
  • Extensively used in stabilizing excavation.
  • Fine particle size penetrates deep into cleavages and cracks to clog pores.
  • Thixotropic properties retained even in highly saline soil.
