Pileman®: bentonite powder for piling and diaphragm walls
High-yield sodium bentonite for slurry support in fresh water. No polymer in it, and made to work with one.
Description
Pileman® is a high-yield sodium-activated bentonite, made by extrusion, for bored piling, diaphragm walls and similar vertical drilling. Mixed in fresh water it gives a thixotropic slurry that holds the wall of the bore, lays a thin filter cake for low fluid loss and holds the cuttings when pumping stops. Hard water is treated with soda ash first. Brackish water takes Pileman® BH.
Used for: Piling · Diaphragm walls
Other Pileman® grades: Pileman® BH · Pileman® Trenchless · Pileman® SDF
What goes wrong on site
What you see on site
What this does about it
- The bore wall starts to cave.
- The slurry presses on the wall and a thin filter cake keeps the water in the bore.
- Cuttings settle when pumping stops.
- The slurry sets to a gel and holds them; stir it and it flows again.
- The ground changes partway down the pile.
- Add our polymer or additives instead of changing the bentonite.
- The site water is hard.
- Treat it with soda ash first, then Pileman® goes in as usual.

Frequently Asked Questions
What is Pileman® used for?
Pileman® is a high-yield sodium-activated bentonite, made by extrusion, for bored piling, diaphragm walls and similar vertical drilling in fresh water. Its slurry holds the wall of the bore.
How much Pileman® goes into one m³ of slurry?
50 kg in 1,000 litres of fresh water. No ageing is needed: the slurry is ready to use within 20 minutes of mixing.
Why price bentonite per m³ of slurry and not per tonne?
Because your pile pays for slurry, not for bags. A good bentonite needs a lower dose, and it seeps less into the ground, so the bore makes fewer cuttings and needs less slurry to finish. A cleaner bore also takes less concrete to fill. That total, not the bag price, is your real cost.
What if my site water is brackish?
Pileman® BH is specially designed for drilling where the water is saline. With soda ash pre-mixed into the water, mix it straight into brackish water up to 5,000 ppm. Drills in up to 16,000 ppm conditions when hydrated in fresh water. Above that, send us a water analysis. Hard water: pre-mix soda ash (light) into the water, then use Pileman®.
Does Pileman® contain polymer?
No. Pileman® contains no polymer but is designed to work with one: if the ground changes, add our polymers and additives instead of changing the bentonite.
How is Pileman® supplied?
In 25 kg bags, stretch-wrapped on wooden pallets, or in 1,300 kg jumbo bags. For pricing, lead time and shipping to your port, ask for a quotation.
Does Pileman® meet API 13A and OCMA DFCP-4?
Yes. Pileman® has been tested to API 13A and OCMA DFCP-4 specifications, and it is made under an ISO 9001:2015 quality system.
Who supplies Pileman®?
Amrfeo Private Limited, a manufacturer since 1994, makes and exports Pileman®, supplying buyers across the Gulf, Europe and Asia. The bentonite is mined and processed at our plant at Bhuj, Kutch, Gujarat, under ISO 9001:2015.
