Bentonite Suppliers, Saudi Arabia
Bentonite is a swelling clay mineral used in drilling fluids, civil engineering slurry walls, foundry sand bonding, iron ore pelletizing, and environmental liner systems. The GCC's oil and gas drilling and infrastructure sectors consume substantial volumes of both sodium and calcium bentonite. Buyers specify bentonite by swelling index, viscosity yield, filtrate loss, and moisture content to match demanding API and construction application standards.

Bentonite is a clay mineral composed predominantly of montmorillonite, prized for its ability to swell when hydrated, form thixotropic gels, and provide sealing and binding properties. Sodium bentonite (naturally occurring or sodium-activated calcium bentonite) is the primary type used in drilling fluids, civil engineering diaphragm walls, and environmental containment liners. Calcium bentonite serves foundry, pelletizing, and agricultural applications. Specialty grades include organoclays for oil-based drilling muds, polymer-enhanced bentonite for horizontal directional drilling (HDD), and granular bentonite for geosynthetic clay liners.
In the UAE and Saudi Arabia, bentonite is consumed in enormous quantities by the oil and gas drilling sector (meeting API 13A specifications for viscosity, yield point, and filtrate loss), by civil engineering contractors for bored pile and slurry wall construction, by foundry operations for sand mould binding, and by environmental projects for landfill and pond liner systems. Procurement managers should specify bentonite by swelling index, apparent viscosity, yield point, gel strength, filtrate loss, moisture content, and methylene blue index depending on the application.
The GCC imports bentonite primarily from India, Greece, Turkey, and the United States. Regional processing facilities in Sharjah, Ras Al Khaimah, and Dammam blend, activate, and package bentonite for the local market. Buyers should verify API certification for drilling grades, evaluate the supplier's blending consistency, and assess inventory management for high-consumption applications. Given the bulk nature of bentonite (typical consumption of 20 to 50 tonnes per oil well), logistics efficiency and proximity of supply to the rig or construction site significantly impact delivered cost.
