Drilling Grade Bentonite for Infrastructure and Foundation Engineering
Product Code: IM-BDG
Industrial Minerals manufactures IM-BDG Drilling Grade Bentonite, a high montmorillonite Sodium Bentonite selectively mined and processed to deliver consistent rheological performance for civil engineering and foundation applications.
Engineered for diaphragm walling, bored piling, slurry trench cut off walls and tunneling support, IM-BDG ensures reliable slurry stability and structural performance under demanding site conditions.
Product Description
IM-BDG is designed to provide superior swelling capacity and thixotropic behavior, delivering:
- Strong borehole wall support
- Reduced permeability
- Improved slurry stability
- Minimal collapse risk in challenging soil strata
