MH Group is a bentonite powder supplier in Pakistan for drilling contractors, foundries, piling and civil contractors, electrical contractors and traders. Bentonite is a clay made mostly of montmorillonite, a mineral that soaks up water and swells into a smooth gel that seals, binds and carries solids.
As a bentonite supplier in Karachi, we serve plants and sites across Pakistan, sell wholesale to traders and distributors, and prepare bulk export orders. Bentonite sits with clays, feldspar and silica sand among the minerals we supply for industry.
Bentonite comes in two main types. Sodium bentonite clay swells many times its dry volume in water and forms a thick, low-permeability gel, which is what drilling mud, piling slurry and sealing work need. Calcium bentonite swells far less but binds and absorbs well, so it suits foundry blends, feed binders and bleaching uses.
Some calcium bentonite is treated with soda ash to raise its swelling, and it is sold as activated bentonite. Ask which type an offer is, because the name alone does not tell you how the clay will perform on your job.
In oil, gas and water well drilling, bentonite thickens the mud so it lifts cuttings to the surface and builds a thin cake that seals the hole wall.
Bentonite slurry holds deep trenches and bored piles open until concrete is poured, a common method on large building and infrastructure sites.
Green sand molds are made from silica sand for foundry molds bonded with bentonite and water, which gives the mold strength and the casting a clean surface.
Electrical contractors pack bentonite around earth electrodes. It holds moisture and keeps close contact with the rod, which helps keep earth resistance low.
Bentonite also lines ponds and landfills, binds iron ore pellets, and goes into animal feed and cat litter.
The swelling figure shows how much the clay expands in water. Drilling and sealing work need a high value.
Drilling buyers test how thick the mud gets and how much water it loses through a filter paper.
Earthing, foundry and drilling grades are not interchangeable, so tell us the end use, the fineness and the moisture limit you work to.
The bentonite powder price depends on type, swelling and viscosity grade, fineness, packing and quantity. Drilling and sealing grades usually cost more than general-purpose clay. Retail packs sold online quote a bentonite clay powder price, or a bentonite powder price per kg, far above the bulk rate for a full truckload.
If your project needs sodium bentonite clay in bulk, share the swelling and viscosity figures your engineer has set. Traders and distributors can also stock it for resale in their own areas.
Drilling, piling, foundry and earthing buyers each get a quote for the type and grade their work needs.
We sell to end users, to traders and distributors, and to buyers abroad from our base in Karachi.
MH Group’s logistics division can schedule site deliveries and book export freight, so the clay reaches the site when the work needs it.
Bentonite powder is used in drilling mud, piling and diaphragm wall slurry, foundry green sand, earthing pits, pond and landfill liners, iron ore pelletizing, animal feed and cat litter. Each use needs a different type and grade, so the application decides which bentonite you should buy.
Not usually. Multani mitti is fuller’s earth, a calcium-rich clay based on montmorillonite, the same mineral found in bentonite. It is close to calcium bentonite but is sold mainly for skin care and cleaning. Industrial sodium bentonite swells far more and is graded for drilling and sealing work.
The cost of sodium bentonite depends on its swelling and viscosity grade, whether it is natural or soda-activated, the fineness, the packing and the quantity. Drilling grades cost more than general grades. Ask for a bentonite powder quote with the specification your project or plant uses.
Yes. Bentonite is widely used as an earthing backfill. Packed around the electrode, it holds moisture, swells to keep tight contact with the rod and the soil, and does not corrode copper or galvanized iron. Sodium bentonite mixed with water into a slurry is the usual choice.
Industrial buyers can order bentonite clay in bulk from MH Group in Karachi, which supplies plants and sites across Pakistan and export buyers. Small retail packs for skin care are sold in shops and online, but they are not graded for drilling, foundry or earthing work.
